Hi I’m waiting on an Elite Suito in the mail and I’m trying to get prepared. My road bike has a 9-speed cassette on the back, I think it’s an 11-30, so I’ll need to replace the 11-speed cassette that is coming on the Suito. I have been shopping online and it’s tough to find a 9-speed Shimano Ultegra or 105 anywhere.
Can I just as well go with ANY style of 9-speed cassette, mountain OR road? There are for example some 9-speed Shimano Alivios and Altus available in 11-28, 11-32 and 11-34, as well as SRAM PG-950 in 11-28. It’s not clear to me whether the SRAM is mountain or road but I think I can put either on. There are some SRAM PG970 (Road) but they are 30-40$ more and they are 11-23s.
So a few questions: Can I do the mtb cassettes? Can I get away with spending $50 as opposed to $90? Also will I notice a big difference between 11-23 as opposed to 11-34?
