• Does anyone do a 12 or even 13 or 14-40T cassette?

    Trying to get some easier gears on a Tiagra 4700 groupset with a GS rear mech. 50-34 front so a 11-40 (with road link) would put it at 45T when the capacity is 41T.

    Will it work ok past capacity or if not, is there a cassette out there that starts at 12 or higher? Top end speed is not an issue and it's not my bike so I really don't want to have a situation where is a risk in certain gears.

  • Be easier to use a praxis Alba 48/32 chainset.

    Gears will shift cleaner, not huge jumps on the gears etc

    I use 48/32 with an 11/32 and find it good, will go 11/34 when this cassette wears out - didn’t originally because 105 spec 11-34t wasn’t out, just ultegra so more than I wanted to spend

    • edit, you can get the 4700gs to work with 36t happily in my experience.
  • i have a 48/32 with 11/30 and its pretty good tbh. 32t would be great too.

  • It would be ideal to change both, but budget wise and £ for gear ratio, putting a 40 on the back would get an easier gear than a 32 at the front. Actually 34-40 is even easier than 30-34.
