• Turns out that the "shop soiled" 2017 Arkose 4 with Mavic rear wheel I bought still had a 10sp cassette on it, explaining why the gears have always been a bit dodge and also weird how they didn't mention it when I bought it or took it for the 6 week service. You'd think the mechanic would say, "do you realise that this bike has a 10sp cassette on it?"

    Anyway, it's in at Cycle Republic in Canary Wharf because I'm a lazy bastard and they're ordering me in an 11sp but what's the biggest cassette I can fit with my derailleur?

  • What’s your derailleur?

  • 11-32, I recommend sticking with the spec, the new 105 R7000 cassette should be out soon and are a lots cheaper, don’t forget to Price Match too.

    I would also write a polite email to Evans about how the mechanic didn’t spot the 10 speed cassette despite the fact it’s clearly not working, did you get the Workmanship card? Technically they shouldn’t have complete the service when something isn’t working and need further inspection.
