>>1364776>A Jtek Shiftmate 1 will take care of the compat issueThat's true but they cost at least £30.
>Miche Primato M cassettes are compatible with Exa-Drive and are pretty cheap, though.They're also around £30 at least from what I've seen. Compare that to a brand new Shimano Claris 8 speed cassette which I've found for as little as £10.95 on Amazon (pic). That's a fucking third of the price, plus you have way more gearing options, since that Claris cassette comes in 11-28, 11-30, 11-32, and even 11-34. The biggest range you can get with the Miche is 13-28 I believe.
>>1364785Yeah I think this post pretty much sums it up. Mixing is not a bad idea due to "aesthetics" or whatever dumb shit reason - it's only a bad idea because Campag rear hubs give you fewer, and more expensive, options for rear cassettes, and because it will be incompatible with Shimano-indexed shifters, unless you spend £30 on a Jtek Shiftmate.
