Good evening All,
I am looking to get a bit more oomph from my new On One Whippet and am considering a more road orientated cassette (11- 30ish) but cannot work out if the GX mech will allow it. I have changed the front ring for a 34 but it is still running out on the flat.
Any ideas or sage advice?
Cheers

Changing to an 11-anything cassette won't give you any more top end.
Simon,
I was actually after a 12 speed cassette with a 10 tooth wee cog but can't find anything.
And also something that would give me more use of the cassette as currently as I live in a pretty flat area the 50 tooth is absolutely pristine! Not sure if I am restricted to MTB cassettes or if a road one would give me more options.

Put a bigger 36t front chainring on ?
Sorry, if I missed the point.
Binman,
I have squeezed a 34 on there but I don't think it will take a 36.

All you'll gain is a closer ratio, which will be better, at the cost of climbing. What's your cadence like as surely you aren't running out on a 34 x 11 other than down hill.
34 x 11 is a 3.1 ratio which isn't far off a 53 x 17 on a road bike (excusing tyres). I certainly don't run out of speed on my road bikes in that gear on the flat, and I'd be pushing a good 23-25mph in that gear.
No idea on compatibility, but would the Deore M6100 10-51 work with Sram GX?

With 2.3" tyres, https://www.sheldonbrown.com/gear-calc.html says with a 34T chainring, that increases your top gear from 89.5 to 98.4 gear inches, roughly equivalent to 50/14 on my road bike on 32mm tyres.
Change the freehub to Sram XD or Shimano Microspline and get a 10 to 50 cassette.
Loads about.
