BACKGROUND – CRANKARM LENGTH Over the past 18 months, I have collected crank arm length data from my bike fit clients. During the bike fit interview process, most of my clients volunteer that they have had prior bike fits, but they are still in pain. Many have had refits and even been to Chiropractors, but they are still experiencing knee pain. Most of the issues I have resolved focus on the following (a) wrong cleat placement, (b) wrong saddle position and (c) wrong crankarm length. Both (a) and (b) above can be fixed by an experienced bike fitter, (c) can be fixed by bicycle and component manufacturers placing shorter cranksets [crankarms] on most bicycles. But first, a background story. Two and a half years ago, 3 best friends, all in their 70’s, started cycling. They have known each other for decades and did everything together. After retiring, they started cycling. First were the shiny new bikes followed by what they thought was a good bike fit. After riding for several months, they all developed severe knee pain. They initially...

LAKE SHOES & NITE IZE mini-reviews

Posted on Feb 8, 2018

A) LAKE CYCLING SHOES Pictured above are the NEW LAKE CX 241 in WIDE (MSRP $349.99) LAKE CX 332 in EXTRA Wide (MSRP $429.99) Both shoes now include the following sizes CX 241 – Built on the COMPETITION last, this shoe is designed for any competitive event.  This is seen by its increased toe pitch and heel lift and a slightly tighter (and heat moldable) heel cup plus wider forefoot (ball of the foot area) which allows the foot to expand from high pedaling pressures. The outsole is the industry’s widest full 100% carbon fiber. The upper is made from abrasion resistant full grain leather. The new closure system is dual push/pull IP1 BOA lacing. CX 332 – Built on a narrow RACE last, but, be warned that even though this shoe is called “Extra-Wide,” it is actually narrower than the CX 241 Wide. This shoe is designed for cyclists with an average E-width foot where the CX 241 is for those up to EE width. The CX 332’s last is full 100% carbon fiber while the upper is...

EXTENDED GEARING FOR THE ROAD BIKE EXTENDED GEARING FOR THE ROAD BIKE PUTTING IT ALL TOGETHER In Part II, we had just about convinced ourselves to build a 1X. We analyzed different gearing options and evaluated the pros & cons of each. We looked at different gearing solutions from both Shimano and SRAM. We also looked at potential rear derailleurs. Lots of data, lots of analysis, lots of decisions to be made. Since posting Part II, I had several long discussions with Brendan at WolfTooth. A very knowledgeable person when it comes to anything MTB, Cross, Gravel and especially running cross-platforms on a single bike. I also want to give a shout out to my mechanic Mark Strohman of R5ciclismo. Summarizing our conversations, WolfTooth Components manufactures numerous rear derailleur optimizations so that it is possible to efficiently run the following; a) Shimano 11-speed MTB shifters & derailleurs with a SRAM 11-speed 10-42T cassette (GoatLink11), b) Larger cassette MTB gearing using a road ‘GS’ Rear Derailleur (RoadLink), c) 11-49T (and larger) cassettes using an extended rear derailleur cage (WolfCage Derailleur...

WOLFTOOTH Extended Gearing for the Road Bike In Part I, we discussed bigger gearing, why use it and how to achieve it. We also discussed the derailleurs total (or maximum) capacity. For those that haven’t read the article, please click here first before reading this one. After publishing the article, I had quite a few emails that said either “Great job, I had been wanting to do this but thought my only option was a triple [3-chainrings in front]” or, I have a question revolving around capacity. So, I went back to the drawing board and mapped out several more gear combinations and my first thought was “Maybe Gerard Vroomen is onto something.” That something is 1X for road bikes…in other words, no front derailleur. In fact, for 2018, the Aqua Blue Professional Cycling Team will be riding this 1×12 bike on the World Pro Tour. What?  1×12?  On the World Pro Tour?  But really, is this so farfetched? Gerard mentioned that the pros are either doing mountain stages or flatter sprint stages. On mountain stages they are either...

THE TRICK TO PAIR A ROTOR POWER METER I see a lot more ROTOR Power Meters lately. From my experience, the new INPOWER and 2INPOWER work flawlessly. But, I have heard from many cyclists that they can’t get them paired to their head unit. So, here’s the trick to pair a ROTOR power meter. Currently, ROTOR makes 2 Power Meters. INPOWER, which is a single sided power meter, and 2INPOWER, which is a dual-sided power meter. These power meters are offered only with a 30mm crank spindle. The reason is that more room is available inside a 30mm spindle than a BB86 (24mm) spindle. Inside the spindle is where ROTOR inserts the electronics. But, for those that have a BB86 bottom bracket (example GIANT TCR ADVANCED), don’t worry, Wheels Manufacturing/Enduro Bearings makes bottom bracket bearings that will insert into your BB86 bb shell and allow you to run a BB30-type crank (SKU BB86-30-BB). See pictures. So, back to the original concern … Why is it so hard to get the ROTOR power meter paired to a head unit? It’s actually...

WOLFTOOTH COMPONENTS ROADLINK REAR DERAILLEUR HANGER EXTENSION aka how to run a wider-range of mountain bike gearing on a road bike. SPINNING IS WINNING How to spin more efficiently is a function of (a) smaller gear inches and (b) high cadence workouts. I recently heard one of Lance Armstrong’s Stages podcasts ( where Lance said “Chris Froome’s gearing up le Mont du Chat [9.2% average grade for 13.5km or 8.4 miles] was 38T in front and 32T in the back. That’s like mountain bike gearing. If you would have rolled up with 38/32 in 1974, the last time they did this in the Tour de France, they would have laughed you right out of the peloton.” To prove this, look at the following video ( which shows what happens if you spin even faster than Lance Armstrong up Mont Ventoux. This video pits Lance vs Pantani at the 2000 Tour de France and Chris Froome against Quintana at the 2013 Tour de France. Ultimately it was Lance & Pantani against Chris Froome. Chris Froome beat Lance and Pantani by...
