I still like to change a front crank set FC-M101. This a simple, square hole, 48/38/28 tooths, 170mm. I search a lot of time to change it. It is not possible to get the same.
How can I know the if the size is OK what I think to buy. (See link)When I write "size" I mean the the horizontal distance from the bike, size of the bottom bracket. (I tried one but it was 5-6 more near to the bike what was to big and also the tooth wheel was not good) I think to buy this in the link in the ebay. Is there any document that shows the sizes (measurements) of the crank set and the bottom bracket?
