- shimano road bike wheels why do they have a max capacity of 30t
because thats the biggest cassette they sell for road bikes. When the biggest road cassette they sold was 27/28 their rear mechs were only rated to 27/28, as soon as they introduced a bigger cassette the limits changed, and I assume they did the same with their wheels. Shimano have always had a rep for being conservative with limits, if you google it theres forum threads/posts for years with people discussing running bigger cassettes than rear mechs were rated for with no problems whatsoever (I did a lot of such googling when I was setting up bikes for the Ronde Van Calderdale which is famous for its 20% gradient climbs!).Posted 3 years agosimondbarnesMember
Oh yes it was……… (when those wheels were designed).
Fine with that caveat I guess as they’re not the newest of wheels 🙂
Claris, Sora, Tiagra, 105 & Ultegra all have mechs rated to work with a 32t cassette these days and there are 8,9,10 & 11spd Shimano cassettes available with a 32t large sprocket that you will find specced on various road bikes.Posted 3 years ago
