Needed to pop the 42 on at short notice and don't have a duo/triple spider
What with having to find either a different, less sexy mech or chain guide, plus permanent modification of either crank or ring, at some point effort exceeds reward. Simplest solution is to get a road double and front mech for the matching shifter, for which I'm rewarded with the right range, no chain drop issues and reduced Q factor. I could get a Duo combo for the Middleburn but is much expoonse and I could put it on my new MTBeater instead

Can't, most triples (AFAIK, but definitely this one) have a slightly larger shoulder diameter on the middle position to stop you doing this. Fuck knows why
