Hello I just bought a ltwoo groupset on ebay because I want to go cheap for my first ride since I'm not sure if I will be riding a lot. I went on the ltwoo website later on and found on that their max cog for their rear derailleur is 50t and I got a 52t will that make any difference?

    Are you referring to a rear derailleur or a front derailleur? 52T is enormous for a cassette's lowest gear, but not impossible.

    @Criggie SRAM released their 10-52t 12s cassette (I suppose to outdo Shimano’s 10-51) and a bunch of overseas companies followed suit.

It’s a 4% increase in diameter. I reckon you’ll be fine. The genuine SRAM systems may be more sensitive, but this one will be just fine.

  • Second that. If your derailleur can take 50 cogs, it should be OK with 52. OEM may disagree. But try it and see. Jul 8 at 11:42
