Adjustable Carbon Cranks

Regrettably I no longer make these cranks.

This post is kept here for interest only.

Thank you, Graeme

The first ever fully adjustable carbon fibre cranks Features Price: Please enquire Weight: 450 - 465 gms. depending on type Range of adjustment: 160 - 183 mm infinite Types: Shimano square and splined drive (road only); Campagnolo square drive Triple adaptors available at extra US$25 Aerodynamically superior to conventional cranks Tremendous strength to weight ratio and stiffness. Converts all energy into forward motion. Adjust to suit leg length and conditions in seconds Why adjustable cranks? The short answer is 'Performance' Would you buy the same frame size as someone 30 cms taller or shorter than you? Obviously you wouldn't, but most cyclists accept the cranks that came with the bike without question. The leg has an optimum or ideal range through which it should travel during the pedalling cycle in order to attain optimum perormance. If the crank is too long or short the leg cannot go through its optimum range and performance will suffer. Enter the Murray TourDeForce Adjustable Cranks These ultra-light (450 gms) ultra-stiff carbon cranks have an infinite adjustment range of between 160 and 183 mms which can be set or changed in seconds without having to buy new cranks and remove the old ones as well as the chain rings and swop them over. This ignores the cost of the new components and the fact that proprietary cranks are only available in increments of 2.5 mms. 150gms lighter than the best hollow forged aluminium cranks, the Murray TourDeForce Competition Cranks can be adjusted infinitely over a range of 23mms in seconds: to exactly match leg length (see table) to accommodate different cycling disciplines - time trial, climbing, triathlon... to accommodate leg length discrepancies Here's what users of Murray TourDeForce Cranks are saying: Graeme, The Murray Adjustable Cranks are the most beautiful component I have ever purchased for the bike. Not only are the cranks a work of art they are the perfect example of precision design and function at its best. There is NO other crank set available with infinite adjustment from 160 - 180 mm. Combined with a lightweight sleek aero design, and superior strength of carbon fibre, the cranks are unbeatable. A truly amazing component. You are a genius Graeme. Alan Ariail, HPV racer, Palatine, IL USA Alan Dear Graeme. I received the most wonderful surprise when your cranks arrived. They look spectacular and I am certainly not a rider whose ability justifies such exquisite componentry. I will take them to the frame builder over the weekend and when the bike is finished, send you a photo. If all works well they will be put to the test in Paris - Brest - Paris next year. I haven't checked my account but if there are any difficulties in extracting payment please let me know. Best Wishes Paul Huard Graeme, I just posted this info on on the message board of one of the most viewed recumbent sites in the US. I hope this brings some business your way. Best Wishes, Alan Bryan, You should post a link for the Murray adjustable carbon cranks. Its a beautifully designed component backed up with excellent customer service. I just tried them on the Jester and they are very light and stiff and they offer infinite adjustment from 160-80 mm. I know that Gerrit once posted a comment on the cranks. With enough interest, Graeme Murray may consider a triple crank desgin. Currently the cranks are only available in a double.
