But the larger sprockets will weigh a few grams more so it'll never catch on!!


That sounds sensible to me. Are there any out there for shimano 11 speed with a 13-32 or similar range?

Miche custom cassettes are available, if a bit pricey (£60 for 13-32).

Otherwise I think you'd have to combine 2 cassettes as I suggest above.

I'm still using 7/8-speed so perhaps not in 10/11-speed (due to the wider range of the cassettes)!

In the past I've used 9-speed and just left off the smallest and largest sprockets (rivets drilled out to separate, but not possible if multiple sprockets are mounted on spiders) to get what I need, but the smallest sprocket is supposed to have serrations to engage with the lockring and stop it loosening. I think you can get away with using the lockring against the next biggest sprocket by tightening it well and maybe using Loctite threadlock, however.

Don't forget to change the jockey wheels to 13T from 11T (less articulation) as well then as even though they are on the low tension side they still have the sprung tension from the derailleur. :wink:
