What to do if i need wider crank???
How i can make wider crank???
Regular bike shops can supply bottom brackets (the shaft and bearing your crank arms attach to) up to 127.5mm. Sick Bike Parts has bottom brackets in 131.5mm, 153mm, and 206mm.

I installed one of the 131.5 units on a customer's bike the other day, and I can attest that they are high quality parts and very fairly priced.

If you have a 3-piece crank you might be able to just get by with pedal arms that bend out. If is the 1-piece crank you will need to replace the whole assembly as mentioned above.

Three piece crank tend to be aluminum. I would not advise bending aluminum.
