Hi,
Anyone had problems with the shifting on an islabikes beinn (20s version fwiw)?
This bike’s shifting has always been an utter time sink (more than the 4 other bikes in the family combined)… I think the problem is that the derailieur can only *just* do as little range across the sprockets that 7 speed requires, so the top limit screw actually limits at the bottom, too (I have photos, but can’t post them). This means it’s *very* sensitive to the hanger’s straightness and cable adjustment, and the stops can’t really be adjusted (good times with the way kids treat bikes…).
I tried a brand new derailieur and it has exactly the same range issue, hence the conclusion it’s only just, if at all, made for 7sp (and/or this spacing). As it is I’ve had to ‘tune’ (bend) the hanger to get it all to work for now, which feels… unsatisfactory, and probably will be temporary.
Anyone had any experience or have any tips?
Islabikes themselves were unhelpful, unfortunately.
