    New cassette for the road

    I want to use an 11-21 or 11-23 cassette on my hardtail to ride on the road. This would replace an 11-32 cassette. Would the derailleur work with this smaller cassette or will I need a road derailleur? Currently using medium cage derailleur and shimano 9 speed drivetrain. Thanks.

    I apologize for the late reply as you may have already figured it out, but no, you don't need a road derailleur to use this setup. The only case that would require a new derailleur is if you were to a wider range cassette with a triple ring crankset. As long as it can take up the slack of the chain in small ring-small cog and allow for use in big ring-big cog, you are fine. But that issue shouldn't exist with the new cassette if it didn't exist with the wider range one you are replacing.

    And for what it's worth, I would strongly recommend using a Shimano cassette (look for an older model Ultegra) rather than a SRAM. They shift much better in my experience.

    Thanks. I took your advice and ordered a 11-21 ultegra 6500 cassette, sram 991 chain and splurged on a close-out xtr 970 crankset. Hope to get my trek elite 9.8 capable of holding its own on B rides.

    an 11-21 is a really tight range cassette. You pretty much never see those used outside of dedicated TT bikes, or people that live in Kansas.

    Those Elite hardtails are such awesome bikes... Definitely a favorite of mine.

    I hope a 44 x 11 is a big enough gear, and always have the 22 for extreme hills. By the way does anyone know if the trek elite 9.8 has a 68 or 73mm bb?
