I need to replace my cassette but assortment is restricted atm.

Can I use the following cassette on my bike?

https://www.sram.com/en/sram/models/cs-pg-950-a1

It's an SRAM PG-950, 9 speed, 11-32T. With regard to those numbers it should be fine on my trekking bike. But what confuses me is that it is explicitely promoted for MTBs. Is that a deal-breaker or irrelevant?

All common 9 speed cassettes use the same freehub body. Also, trekking bikes normally use MTB parts, so there is no problem there. The Acera line is an MTB line. The manufacturers normally only distinguish (with some exceptions) road/MTB/urban and other bikes like hybrid, trekking, gravel, cyclocross take many components from those lines with only a few specifics.

Just check that your Acera rear derailleur actually allows this 11/32 range, but it should. All should be OK.

  • Okay, that's why I only find racing bike and MTB as categories. Good to know. – Raffael Mar 21 at 22:16
  • Gravel is emerging as a third category, with technologies pulled from both road and MTB (see e.g. Shimano’s GRX line, which is a road-like groupset with wider gear ranges and MTB-based features like the rear derailleur chain stabilizer, although that also features in some road groupsets now). – Stephen Kitt Mar 22 at 9:27
  • @StephenKitt I did mention the exceptions. Many gravel bikes, including my own, still take most of the components from the road lines. You will still find Ultegra or Dura Ace instead of GRX even among professional racers. – Vladimir F Mar 22 at 9:31
  • @VladimirF sorry, I was responding to Raffael’s comment, not your answer. And yes, I noticed a lot of non-GRX setups in this year’s cyclocross and gravel races! – Stephen Kitt Mar 22 at 9:46
