1x10 conversion from 3x10.
Gains, some weight loss, simplicity of shift operation, quick snap into 42 on steep climb vs dropping to granny then shifting down so not spinning madly. No risk of chain drop shifting to granny under pressure.
Losses: big ring up front for pumping descents, will now spin out at 40 kph vs around 55-60 kph with triple - , no granny help when legs are truly stuffed.
Why he no go 1x11? weight of 1x11 vs 11-36 XT cassette, my training bike is 1x10 so I always recycle parts down to that, 1x11 got tricky cost wise, new cranks? Or a 1x11 after market ring with 1x11 cassette, then I would need new 1x11 shifter - which would mean the training bike would need new shifter as well, ,
How's it ride so far? I already know from training bike how 34- into 11 feels, its fine for 99% of mtbing, climbing with 42-34 is the main question .... so far the mega steep climbs I've tried it out on are fine, not a bad gear to maintain good cadence on 15%-20%. If you're a new rider and you don't have either the endurance or strength on climbs then the 42 might tip you over the edge fatigue wise. The granny has its merits to bring you home without walking the climbs.
Set up Tips: will need narrower chain ring bolts - lock tight them in, preset B screw (had to screw nearly all the way in) & low/high screws before putting on chain, if using clutch on rear derailleur, shifting is pretty stiff - haven't
'dropped chain yet' (with clutch off!) get new chain sizing right as you would normally.
Chain Line?: hmmm if I run a straight edge from front ring to rear it ends up around middle of rear cassette, so that's where most of your riding is? either side of middle cassette. Wait and see if there's rapid wear on front ring/chain.
Chain Slap? on rocky descents didn't expect it to be so quiet so far.
Bling, 42 tooth looks nasty on rear. yells bang me on and climb stuff dude.
