was that with xx njee as you seem to like to remind us?
I don't do much reminding actually, in fact in the numerous threads about doubles that crop up I talk about my 9 speed set up rather than bleating on about XX, but yep it was. I suspect the culprit is more the frame than the chainset, as I've been running doubles on previous bikes for years. On the plus side the cassette didn't clog at all, and the shifting was still spot on! The jockey wheels are totally worn out now though, which isn't particularly impressive considering the laughable price of OEM replacements.
You weren't descending slowly on the STW Surrey Hills ride Nick!
Aaw, thanks! It does help that I know those trails rather well. That puncture was very odd, a true 'pinch' flat!
