I have lost 3 bolts which hold the gears together
24 Apr 2020
I think these are called the crank bolts, they are from an alpha drive fsa unit
Hi, this is the bolt that holds the crank arm onto the bottom bracket axle. I think you are looking for chainring bolts if you need three. Thanks 28/04/2020
I Am After A Chainring Bolt. The One That Goes On The Inside Behind The Crankarm.

I stupidly over tightened mine and the head of the bolt tore off. luckily I have managed to exert the rest of the bolt.
I have tried looking everywhere online and cant find one for my chainset. Miche Microtech compact 50/34. I have managed to find plenty of the male/female bolts but no such look with the single bolt that goes behind the crank arm.
Having come across your website I see you have plenty of spare parts but unsure if any would be compatible for my chainset.
Hoping you can help and have such a bolt in stock or can point me in the right direction in finding one.

Unfortunately we have got no way of knowing exactly what bolt is is that you require for your chainset as we have never sold them. The best suggestion we have is that it may be an inner chainring bolt used, as these normally thread straight into the crank arm, all we can recommend is trying an inner chainring bolt and seeing if that fits.
