Crazy Town Build

one piece crank

So I’m about to convert my favorite bike from SS to 1x. I originally built it with leftover 24” DH tires & rims, well before plus bikes became a thing. I’d swap DJ tires on it for the Alexandria Pump Track and also hit the Flemington indoor skatepark. Well, no more pump track, or skatepark, and although SS kept me fit for the past 10 years, it kinda kicks my butt these days. Modern clutch deraileurs and gear ratios have really changed things for the better, and can help me keep this beast as my do-everything bike.

Glory shot:

The rear end is currently 14x135, but can also take 10mm-bolt-on/10mm-thru, or bore the adaptors for 12mm thru. I’m kind leaning toward a 10mm thru with a Saint solid axle.

My big dilemma is what 1x kit to put on? I was looking at SRAM 1x11 (NX/GX) to get that 42T cog, but are there any advantages to going with an older 1x10 or 1x9?

Any suggestions?

how does the derailleur get hung?
Is there a kit specific to that frame or is it generic?

i just put the 1x11gx on the fatbike. 42t is available in 9sp (got one on the old fatbike) - in case you have parts around to repurpose.
otherwise the cost jump isn't that much.

That set up on the 456 you bought from me was ace. Run one like that. I put xt 1x 11 on the Knolly and love that, but im not sure i would have bothered with that on the hardtail.
