What length for triple chainset
01 Nov 2023
I need a 43.5mm chainline and my chain set is a shimano Octolink V2 FC-M431. Is the 113mm BB the correct length. The BB shell is 68mm. Thanks.
113mm axle will get you the closest to your required chain line, the crank set is designed around a 50mm chain line using a 118mm axle. SK 02/11/23
