Help!! Cranks!!!
 

does anyone know where i can find 145mm cranks? What company makes them? this is for a track bike. thank you

Bulletproof makes 145mm cranks - can't find a website to verify this, but I am 99% sure

Is this for tatoo, the wizzard (hope somebody remember the tv show) or is a surprise for one of the Humpa Loompas???

ED: umpa lumpa, thats better? :p

uh... humpa loompa?

sheldon only has bulletproofs in 140 and 150, no 145's
not sure if bulletproof even make 145's

here are some 145's for your midgetbike

its not for a midget bike. i have pedal overlaps(like in this picture) and i think the only way to fix that is to get shorter crank arms.

Thats a crazy amount of overlap, but 145s will make your pedal stroke pretty weak. You'll lose about 15% of your power (assuming you have 170mm cranks now)

hehehe... u r trying to find a solution to something that virtually do not have a solution, because it is that way. Looks like your frame it is quite small, I would say 52? maybe smaller? More over u are using large clips that makes the situation even worse.

Sincerelly U r trying to find the answer to something that will be like that ever, I know of a guy that can cut the cranks for u if u want to, but u'll end with a set of cranks too shorts for u... Small frames have that problem and if u have a feet size 13 there is no way u know...

Let me tell u this... In track bikes (have no clue what bike do u have) from 49 throught out to 56/55 all the bikes have problem with overlaping. My advice? do not spend money in stuff, and learn to ride like that, isnt hard at all u have to sync your pedaling and the driving, thats all... as a patch solution u can cut your feets just in the midlle u know, that would work...

good luck :)

dude, i ride a 60cm frame with eggbeaters and i still have toe overlap. in an ideal world, there is no reason for you to ever have to worry about toe overlap anyway. front wheel movement is pretty minimal.

Start with some 67.5mm cranks with the right shaped end and Mark should be able to shorten them to 145 for you. I know him personally and he is an excellent craftsman.

Says who? Some sources would disagree with you. Lennard Zinn (who is 6'6" and sort of an expert on bikes for tall people) ended up outputting the most power with a 150mm crank. Who knows, at the lower cadences of street riding, a really short crank might end up being perfect.

looks like they didn't adjust the saddle fore-aft when they swapped cranks.
which, if true, kinda makes those results pretty useless
