On the contrary, 2x10 bike setups are getting more common these days even for MTB, all the manufacturers offer 2x10 setups.
One big advantage is that all combinations on a 2x10 are usable, whereas with a classic 3x9 you have to avoid being at high gear up front and low gear at the back, or you will be crossing the chain and damaging components / dropping chain.
- patchorang 5y agoI think they were referencing mountain bikes. They are nearly all 1x now.
- PaulDavisThe1st 5y ago.. and i still don't understand how we're all just supposed to ignore the monster chain crossing that this setup implies.
- Kluny 5y agoIt doesn't seem to be much of a problem on my 1x mountain bike.
- discreteevent 5y agoIt's less crossing than 2x at the extremes
- semi-extrinsic 5y agoI run a 1x10, and there is no problem with chain crossing. The 10/11/12 speed cassettes are basically not any wider than the regular 9 speed ones, so there is no more chain crossing than what you get for the middle ring on a 3x9. The optimization is all in narrower chains and sprockets. That being said, I do run an upper chain guide to reduce probability of the chain falling off the chainring when the rear derailleur gets clogged with mud etc.
