I’ve been doing this for a while. I run a 34t ring with a Gamut P20 on my Prophet. I can ride up most things fine. The only real problem is occasionally running out of gears on the flat-out descents.

If only the roller on the Gamut was a bit softer. The constant rumbling noise gets on your nerves after a while…

I ride everywhere with the 36 front ring on my Alpine.. partly because I havent fitted a front mech yet.. partly because I have the legs to push a 36!

it’s definetly do-able. I live in Colorado where most of our trails are “climb for an hour, descend for 15 minutes”. After a few years of steady riding in this state – I almost never use my 22t… all my climbing is in the 32. the 42 ring on my bike is also too big… so if you have the legs it certainly makes sense to push a single ring like a 36t or 38t (adam craig will sometimes push a 40t). Around here – I’m riding a 34t these days and occassionally go down to a 32 for long climbing days).

The new Sram xx with a 36t cassette also makes a big difference in the single ring scenario.

yeah – i certainly wouldn’t want to run 1 x 9 on my XC bike… but then again my legs don’t look anything like that fellas in the pic!

I guess it’d be great for a nice little hack bike for local rides – maybe a light weight DJ/4X build or something?

Those guys must have strong legs – you’d not want to consider climbing around here without a 22t ring up front. What does this chap run up front? 32 or 36t? Interesting development though.
