I've enjoyed the conversion to drop bars on my Litespeed MTB, but I haven't got the shifting to where I like it - it's finicky. But I'm definitely pushing the frankenbike approach here. I have a 11 sp Microshift bar end shifter, a 11-40 10 sp Sunrace cassette, and an 11 sp Shimano XT rear derailleur. The 11 sp rd is what's needed to clear a 40T cog, and the 11 sp Microshift is made to have the right pull for the 11 sp rd. The cog pitch on the 10 sp cassette is 0.05mm different from the cog pitch on the 11 sp cassettes - so 0.5 mm or 0.020", over the whole cassette. I doubt this is the issue. But I have three components from three manufacturers and trying to get them to play nice.
Meanwhile, what I really wanted was a top of bar thumbshifter set-up, and I have a set of the VO thumbies coming - but the Microshift won't fit those. I have a set of Shimano 10 sp bar end shifters, which fit the VO thumbies, but would need a Wolf Tooth Tanpan to adapt the road shifter cable pull to what the rd needs (Wolf Tooth says this would work with the 11 sp rd, BTW). Before I throw yet another $40 at this project, which started as a parts bin conversion, I'm trying to decide if the smart thing is to bag the 1x10, and go back to a 2x9, which gets back to a 34T big cog and an 9 sp XTR rd I have, with 9 sp barcons I have and which will fit on the VO thumbies.
Last thing is, I have been using a 105 crankset with a 39T single chainring which is not a narrow-wide, chainline is perfect, and yet coming down a dirt road a couple of days ago I threw the chain despite the rd being a clutch model, and it really got wound up in the crank :-( So at the moment i have the XT fd back on the bike as a chain guide - it's not a very far step to give it a shifter :-) and I know the 9 sp stuff shifts bombproof.
Thoughts appreciated...
