Laurence--Trials Posted October 11, 2010 Report Share Posted October 11, 2010 Without your chainring (im sorry im not sure what one of these is) you can use a spacer in there. Quote Link to comment Share on other sites More sharing options...
Mark W Posted October 11, 2010 Report Share Posted October 11, 2010 not sure what length to be honest Then measure it what is a suitable length Longer than your answer to the previous bit But seriously, you're probably going to struggle to get that setup to work...

tdubz Posted October 11, 2010 Author Report Share Posted October 11, 2010 Then measure it Longer than your answer to the previous bit But seriously, you're probably going to struggle to get that setup to work... maybe another set of cranks with a smaller chainring might be the only solution then Then measure it Longer than your answer to the previous bit But seriously, you're probably going to struggle to get that setup to work... but this guy seems to be running a simlar set up http://i847.photobucket.com/albums/ab32/mrmad4uk69/ac7d38fe.jpg Quote Link to comment Share on other sites More sharing options...
