Distance between the dropouts is 135mm (this measurement)
BB Width = 68mm
Crank Arm Length required = 170mm
Tyre Size = 26x1.50
I want to go for a 42T chainring with a 16T cog at the back. Do I need to know any other measurements to ensure I buy the right chainset/BB?
I've read somewhere that with 135mm rear dropout spacing a BB length of 113mm would be suitable but is that right? How would I know?
I was thinking about going for this deal
: Stronglight 42T chainring with a 113mm (length) BB for a total of £34.99
I'm also gonna buy a SRAM chain
Any help/advice appreciated, thanks.
