Flat Pedal Upgrade?

I am so old school that I run flat pedals on all my bikes including my road bike.  Been pedaling bikes for 45 years and spent a significant number of years riding and racing motorcycles and never have my feet been mechanically attached to my pedals of foot pegs.  I also own a closet full of 5-10 shoes to keep my feet firmly attached to my pedals. 

This blog post is not about “Flats vs. Clip in” pedals and I feel pedal choice is a personal one and my choice is flats.  This blog post is just about my personal search for a better flat pedal and nothing more.

For the past 5 years my go to pedal set up was some light, durable, fairly thin, and inexpensive Welgo B103 and B118 flat pedals.  I would replace the original soft aluminum pins with some steel ones made by Xpedo and the pedals would wind up costing about $60 a pair.

I liked the platform size and shape and the high pin count which led to great grip and control.  Life expectancy ran about 2 years per pair until I smashed enough rocks to damage the pedal body or wore out the non-serviceable inboard bushings.  

Life has been pretty good with those pedals but I started following the movement towards ultra thin flat pedals and wanted to give them a try.  There are claimed benefits to improvement in eliminating the dead spot at the bottom of the pedal stroke by moving your foot closer to the pedal spindle centerline.  The claims the thinner pedal body will improve ground clearance to minimize pedal strikes on rocks and roots seems very logical but the noticeable impact would seem to be proportional to the thickness of your current pedals.

But there were barriers; some pedals have rider weight limits that prohibit my 220lb carcass from safely riding them.  And, the costs of these ultra thin pedals seem to start around $150 with some approaching $300.  My mind had trouble justifying such a price tag when my go to pedal setup worked great and could be had for a mere $60.

So, for the 2015 racing season I decided to bite the bullet and jump head first into the ultra thin lifestyle.  After doing research and reading all the on-line dribble, reviews, rants, and keyboard jockey wisdom I decided on the Canfield Brothers Crampon Ultimate Pedal.

Still being cautions and somewhat tight with my money I chose try the 342 gram aluminum version over the even lighter 280 gram (but $50 more expensive) Magnesium version.  But honestly, the decision also came down to the fact I could match the accent colors on my bike better with the Anodized colors on the aluminum vs. the painted colors on the magnesium pedals.   And who doesn't enjoy throwing back a cold brew while admiring their bike after a ride and saying to them self, “damn that is one nice looking bike”.  Now, style is in the eye of the beholder but I just had to have orange pedals on my Tallboy LTc and red ones on my Nomad for personal style points.  You go faster when you look good right?  So I contacted Canfield Brothers and ordered some up.

Note:  the pedal body thickness that is less than the pedal spindle diameter.

One of the problems I have had since I began racing 4 years ago is high speed crashes caused by pedal strikes.  Pedal strikes frequently occur while trying to get those precious few additional pedal strokes in to shave a few seconds off my race times.  These pedal strikes unfortunately have led to some serious crashes/injuries and this is the primary reason I want the ultra thin pedals.

The ultra low bottom bracket on my new Santa Cruz Nomad 3.0 also prompted me to recently switch out the 175mm crank arms for some 165mm ones.  This made a noticeable reduction in pedal strikes so I doubt I will notice too much additional improvement directly from the pedals but I will welcome a little additional clearance none the less.  I still run 175mm crank arms on my Santa Cruz Tallboy LTc so I should be able to readily assess the reduction in pedal strikes due to pedals alone on this bike.

Stay Tuned for the next installment of this blog after I have spent some pedal time on these beautiful Crampons and competed in a few races.

Wolf Tooth Chainrings and Cassette Conversions

In 2014 I had a 4 bike quiver:

26” wheel Santa Cruz Blur LTc for general riding using a 30t Wolf Tooth GPX Direct Mount Drop Stop Chain Ring, a Shimano XT 11-36t 10sp rear cassette, and 2013 Shimano XT 10sp Shadow Plus Med Cage derailleur.

29” wheel Specialized Crave SL for cross country and cyclocross racing using a 32t or a 34t Wolf Tooth GXP Direct Mount Drop Stop Chain Ring with Shimano XT 11-36t 10sp rear cassette converted with a Wolf Tooth 42t Giant Cog, Wolf Tooth 16t cog, and Sram X9 10sp Med Cage Type 2 derailleur.

29” wheel Santa Cruz Tallboy LTc for enduro racing using a 28t or a 30t Wolf Tooth GXP Direct Mount Drop Stop Chain Ring in combination with a Sram X01 11sp derailleur, and 10-42t 11sp cassette.

27.5” wheel Santa Cruz Nomad for riding bike parks, enduro racing, and downhill racing using a 34t Wolf Tooth GXP Direct Mount Drop Stop Chain Ring in combination with a Sram XX1 derailleur, and 10-42t 11sp cassette.

You will replace front chain rings more frequently on a 1x drive train vs. a 2x or 3x front chainring set up and there is no way around that.  Also front chain rings with smaller teeth count will wear faster than ones with larger teeth count due to concentrating the wear on a smaller number of teeth while pedaling.  I have found that Wolf tooth Drop Stop Chain Ring wear has been excellent even though wear is concentrated on one chaining all the time and I tend to run smaller front chainrings to make climbing easier on my arthritic 49 year old knees.  I am getting the same amount of life out of the Wolf Tooth Drop Stop chain rings as the much more expensive Sram 11sp chain rings I replaced on the Tallboy LTc and Nomad. 

The GXP direct mount chain rings offer a cleaner look and they are significantly lighter than the “Spider” style Sram chainring setup that came stock.  Sram has recently announced a direct mount chainring option but they are not American made and still more expensive than those offered by Wolf Tooth.

There are several other companies making similar wide/narrow tooth chainrings and wide range rear cassette conversions but only Wolf Tooth products are made 100% in America and to me that is very important.  I buy direct and my order ships from Minnesota by the next business day and arrives at my door no later than 3 business days from order placement and free shipping on orders over $50.

I personally think the Wolf Tooth Drop Stop Chain Rings look awesome, they save me money and weight, and I never suffered a dropped chain or drive train failure in 2014 during any rides or the 42 races I competed in (including several really good crashes). Note: I am using the correct 10/11 speed chains and clutch type derailleurs as recommended by Wolf Tooth.


My 1st Drop Stop Chainring was installed on 1 1x9 drivetrain with pretty good results

When I got my first Drop Stop Chain Ring and added it to an older 9 speed bike with no clutch type derailleur against the recommendation from Wolf Tooth I would occasionally drop a chain on DH terrain when using smallest 3 cogs on rear cassette.  However, an MRP Top Guide was all it took to solve that problem.


Who needs 1x11 when you have this awesome 11-42 1x10 drivetrain!

From my experience the 42t Giant Cog and 16t cog rear cassette conversion works flawless with a Sram X9 10sp Med Cage Type 2 derailleur and a Drop Stop GXP Direct Mount front chainring. I used this set up on my Crave SL 29r for Cyclocross and XC racing and suffered zero dropped chains in 18 months of hard racing without the use of a chain retention device. I enjoy a completely quiet drive train free of chain slap, and a full range of race gearing using 34t front chaining for Cyclocross and a 32t for XC Racing.   It is hard to tell I am not riding one of my XX1 or X01 1x11 equipped bikes.  I was able to buy the X9 shifter and derailleur, a 10sp XT cassette, the Wolf Tooth 42t Giant Cog, and Wolf Tooth 16t cog for less than the cost of a Sram XX1 or X01 cassette.  Yes, it weighs a few grams more than the Sram 11sp drive train, but it performs nearly as well.  On a price to performance ratio I think the full Sram 11 speed drivetrain is the loser in this comparison. The only real world performance advantage of the Sram 11sp drive train is the 10t rear cog.  That 1 tooth smaller cog transmits into several MPH greater top speed but that only really matters in highly competitive racing.

I however had a different experience trying to do the conversion on my Blur LTc a bike equipped with a 2013 Shimano XT 10sp Shadow Plus Med Cage derailleur.  The derailleur was not compatible with the 42t Giant Cog even using the extra long B Screw purchased from Wolf Tooth.  The arm that secures the cable would rub against the 42t cog in almost every gear and that conversion attempt never made it past the repair stand.

Wolf Tooth does have a solution for Shimano derailleur issues like I experienced in the form of the Goat Link.

My Year With ChainBrew

My Year with Chain Brew:

In the summer of 2013 I was introduced to the company Chain Brew at the Oregon Enduro Series race in Hood River, Oregon.  I obtained a few of their sample size bottles of chain lube as they were tossed into the crowd during the awards and raffle after the race.

https://www.facebook.com/ChainBrew

http://terraincontrol.com/chain-brew.html

Two things interested me right away; this chain lube was locally made by some of my fellow racers and it smelled good.  Yes, chain lube that you actually enjoy smelling.  I am not sure exactly how they do it but the lube smells like root beer and does not have any chemical odor to it at all. 

At the Bend Oregon Enduro stop the Chain Brew folks were set up and selling larger bottles of the lube and several of my EPIC Racing Cycling Team members and I bought a few bottles.

I began using Chain Brew throughout the remainder of the dry summer months.  I was impressed on how clean the lube was and after the first ride only a minimal amount of dirt collected on my drive train. With a rag you could just wipe the chain, cogs, chain rings, and derailleur pulleys clean and the drivetrain would remain clean ride after ride. 

Old habits are hard to break and growing up on the “wet” side of the Cascade mountains had taught me to re-lube my chain after every wet and muddy ride otherwise even the highest quality chain would turn “orange” by the next day even using thick and sticky “wet” lubes from various companies.   What I discovered with Chain Brew was the mud and water would bead up and drip off my chain resulting in a cleaner drive train during these mucky rides.  I also noted less of the dreaded “orange” chain whenever a bike was put away without cleaning and drying immediately after a wet and muddy ride.


2014 Spring XC Racing in the PNW - Mud was not sticking to my single speed chain today!


I do not use any electronic devices when I ride or race so I cannot give you exact figures on how long my chains, chainrings, and cogs last in miles, hours, or feet of elevation gained before I replace them.  But, from January 2013 to January 2014 I entered and finished 42 races that were a balanced mix of cross country, enduro, downhill, and cyclocross.  I also ride an average of 4 days a week year round and in Western Washington the majority of those rides are in wet and muddy conditions.

I have a 4 bike quiver: A Santa Cruz Blur LTc for general riding, a Specialized Crave SL for cross country and cyclocross racing, a Santa Cruz Tallboy LTc for enduro racing, and a Santa Cruz Nomad for riding bike parks, enduro and downhill racing.  I run Wolf Tooth Drop Stop single chain rings on all 4 bikes and either a Sram 11sp or Wolf Tooth Giant Cog converted wide range 10sp rear cassettes.  I am meticulous in my maintenance regiment and I measure my chains with a Park Tools chain gauge regularly and replace them once they reach 5% stretch.  I also replace the front chain ring after the 2nd chain is replaced.  Doing this has eliminated the need to replace the expensive rear cassettes for several seasons and I have not suffered any drive train failures during competition.

In 2014, on the Tallboy LTc, I replaced the chain twice and the Wolf Tooth front chain ring once but at the same time I replaced the Sram GXP bottom bracket twice to give you a sense of the use and abuse that bike took.  On the Crave, I replaced one chain in 2014.  The Nomad and the Blur LTc don’t see near the miles of the other bikes and still have not reached 5% chain stretch nor needed any other drive train part replacements. 

So, in summary, my 2014 riding/racing was spread out over four bikes and I replaced 3 chains, 1 chain ring, and 2 bottom bracket bearing sets due to wear.  It may be worth noting I am 6’ tall and weigh 220lbs so I do put a lot of stress on my bike components.

In 2013 prior to my sole reliance on Chain Brew Chain Lube and Wolf Tooth Chain Rings I used 3 bikes and they were set up with 2x9 drive trains.  My amount of riding and racing in 2013 was less than in 2014 (no Down Hill or Cyclocross racing).  In 2013 I wore out 2 bottom bracket bearing sets, 5 chains, and 2 sets of 2x chain rings.  Note: Chain ring wear is not directly comparable between 2013 and 2014 due to spreading the wear over multiple front chain rings on the 2x set up’s versus the dedicated 1x set up’s used in 2014.

I fully admit that there no way I could claim this is a scientific test of how Chain Brew reduced drive train wear because I never kept track of my miles, hours, or feet of elevation gained.  The only thing that I can vouch to is; I put a lot fewer miles on my drive trains in 2013 using another company’s wet lube vs. 2014 when I used Chain Brew exclusively.  So, the anecdotal evidence is I wore out fewer chains and chain rings even while increasing the amount of riding and racing significantly the year I used Chain Brew exclusively.

I do know for a fact that Chain Brew has significantly reduced my drive train maintenance.  I have not needed to break out brushes and degreaser to remove any build up of greasy gunk from my chain, chainring, cassette, or derailleur pulleys.  I do not miss the greasy chain tattoos on my right leg or clothes when I brush up against the bike.  And, I can lube my chain in the house or a motel room without stinking up the place with chemical odors.


 Just finished a CX Double Header in Dec 2014 - good and muddy it was!

Other uses:

I was having difficulty with the free hub pawls sticking on my Easton Haven wheelset so I began using chain brew as the lubricant.  I have enjoyed a year and a half of reduced drag and consistent and positive pawl engagement.  I also begun using it on my Crank Brothers free hub pawls and have felt improved performance on them as well.

It seems to make a clean and effective cable lube and has extended the life of some derailleur cables that were getting sticky and affecting shift performance.

I used it on some door hinge pins in my home but the dogs keep smelling and trying to lick them.  I attribute that to the root beer smell and Chain Brew even places a large warning on the bottle to keep away from children.  

More details on Chain Brew formulation:

While Chain Brew holds their exact formula a close secret, the following information was researched on the main ingredient found in Chain Brew and how it works to reduce friction and provide the excellent drivetrain performance I have experienced. 
   
The main Ingredient in Chain Brew is a high concentration of polytetrafluoroethylene (PTFE) most commonly known as the DuPont trademarked material Teflon.  PTFE’s coefficient of friction is the third-lowest of any known solid material and is the only known surface to which a Gecko cannot stick (actual fact).  Chain Brew’s formula seals out moisture, inhibits corrosion, and is highly resistant to dust and dirt build-up.

Chain Brew is considered a dry film solid lubricant and is an aqueous dispersion of finely divided PTFE particles that are less than 10 microns in size.  It goes on wet but will air cure leaving the PTFE solids bonded to the chain surfaces providing a durable, dry, colorless coating with excellent lubricating properties, a low coefficient of friction, good corrosion protection, and excellent mud shedding characteristics.

Dry film solid lubricants are useful for conditions when conventional lubricants are inadequate, such as sliding or reciprocating motion that requires lubrication to minimize wear in gear and chain applications. Dry film solid lubricants offer protection beyond the normal properties of most mineral and synthetic oil-based fluid lubricants.  Mineral and synthetic oil-based fluid lubricants will squeeze out and quickly lose their lubrication and wear protection ability plus they attract dirt and contaminants to your drive train that will require frequent degreasing.  Dry film solid lubricants do not squeeze out and they prevent corrosion while offering greater friction protection for longer periods of time.  Dry film solid lubricants do all this without attracting dirt and contaminates to your drive train like mineral and synthetic oil-based fluid lubricants do.

For optimal results Chain Brew should be applied to a clean, dry chain by applying a single drop at each chain roller location.  Turn crank several times to aid in wicking lube into the chain rollers.  Let stand and then wipe chain off with clean rag.

Re-lube intervals depend on your mileage and riding conditions.  In dry weather conditions, periodic wiping off of the slight amount of surface dirt should be all that is necessary.  Chain will appear clean and dry but the dry film of PTFE is providing the required friction and wear protection.  Reapply Chain Brew as soon as the chain is beginning to “sound” dry and is making some slight noise.

In wet weather, it is recommended to apply Chain Brew much more frequently for corrosion protection.  I have found that in the very wet winter months in the Pacific Northwest I need to reapply Chain Brew after about 2 rides or if I washed the bike off with a hose.  You will notice during muddy ride the water and mud literally beads up and drips right off the chain.  This reduces drive train wear by reducing the amount of “grit” that tries to grind away at you chain, chainrings, and cogs.  It also minimizes any mud buildup that will cause shifting problems during rides and races.


Early Spring 2015 The XC Racing has been a bet wet!

Since the PTFE particles settle in the aqueous solution during storage, agitation is required to maintain a uniform dispersion.   Make sure you shake bottle vigorously prior to removing the cap and applying to your chain.
