11 Speed, Single Chainring MTB - Won't It Cross Chain?

[woodbine]

Was wandering around Halfords earlier and thought I would have a look at the bikes on sale. Noticed a MTB with 11 rear sprockets and single chainring. So, won't a setup like this cross? Or, does it have a special chain, etc? Have I missed something?

The single front ring sits closer to the centre line on the rear cassette meaning you only go 5 or so cogs either way from the centre one.

Note that SRAM advertise all gear combinations (including big/big little/little if that's what you want) as being useable on their compact double groupsets.

User33236>>>>>>> Thanks. That makes sense, but I would imagine that if the chainring was mounted in line with the centre rear sprocket, ranging between 6 sprockets either way must be on the limit.

And they totally are

The majority of 1x users aren't really going to care much for a little extra chain wear(if there is any?) Considering most of the systems appear on MTB, CX and gravel bikes a bit of crosschaining is probably the least of the stresses it will endure

I have 11 speed mtb..
you only really use the extremes for short periods..
plus your on narrow wide front sprocket and a thinner chain so not that much twist.
it works beautifuly as it happens

Thanks for all the info. I run a 30 year old MTB with 18 gears (Uniglide/Biopace). Suddenly I don't feel quite so guilty for occasionally running in large outer front ring and large inner rear sprocket occasionally.

I'm considering getting a modern hack for everyday use so the 'retro' can have an easier life in old age (some drivetrain parts are getting rare too, so lowering wear would help). Poss new or nearly new, but not big money. A MTB mainly for road, but preferably with no more than 18 gears - as I'm too lazy to swap through more. Definitely want Shimano, etc quality drivetrain - but lots of new 18 gear bike seem to have cheap gears.

Single speed?

Single speed?

Just bought a cross bike with SRAM rival 1 and so far, it works fine. What you have is alternating thick/thin teeth on the chainring (and I believe jockey wheels) that help to keep the chain in the right place.
