I have been chatting to Kernow about cassette option's, for a second set of wheels that are to be used on tarmac, the only Cassette available, as far as I can find, is the, XG 899 E Block 11-48 8 speed. It's a fair chunk of change and its spread of ratio's is just too wide for the road. If anyone has any insight's on alternatives that might work, or has actually done it :D I would be keen to hear from them. :)

As I understand it :confused: EX1 uses an 10 speed chain, with eight cog's that have, ten speed spacing, with a single click, ten speed shifter that is limited to eight shifts o_O

It can't be as simple as just buying a 10 speed cassette and only being able to use the top eight can it :unsure:

Maybe use spacers from 10spd cassette with 8 gears?
Don't think you will be able to get a higher gear via cassette without either going 11/12spd SRAM using the XD driver or one of the exotic gear sets out there. 11T is the smallest on a Shimano hub as far as I am aware. Easier to change a front ring to increase gearing. Doesn't help with a second set of wheels......

Hey Ecky

Don't really want two spend any more out on XD driver, if I can help it......found this.......it's cheap at the moment...and the top eight ratio's would be

11-13-15-17-19-21-24-28-(32-36)T

Alternatively, offload that ghastly SRAM stuff on someone like me and get yourself a nice reliable Shimano 11spd setup, you will have lots of nice close gears then?

TBH I already have everything I need to convert it to XT M8000, but I am really hoping that the EX1 is the way to go, makes so much sense.

Especially if someone makes an 11-42 for it, just to tighten up the gaps a smidge, I think that would be perfect :p

You can change the big ring on SRAM 11 & 12 spd cassettes, you may be able to do the same on EX1.
I'm pretty sure the big four gears are machined from one piece of hardened tool steel, it's the four smaller ones that are replaceable individually :rolleyes:

But I will check :D

I don't know how this works with other motors, but if you have a a bosch motor, I think you need to update your software if you change your cassett and the biggest or smallest cog changes more than 10%.

FYI, take the EX1 cassette off and grease it.

The B adjustment is critical for smooth shifting.

Spines are a good idea in general, but specifically there is a floating spacer inside the cassette that will squeek in certain gears if not properly lubricated.
