    Drop to a 16t on the back, you will be fine.


    i used to mess about a lot changing from 17-18-19-20T.

    then i looked at a cassette and saw 2T jumps are normal 3T not unusual.

    I hardly bother anymore…


    The sums say it’ll be about 6% harder if you drop a tooth. It’ll only cost you one cog to try.


    I even get an answer that includes maths! Well impressed!
    My main concern is that 32 16 would be equivalent to something like a 32 14 on 26er and I’m pretty sure that running in that gear all the time would be quite gruelling…..
    But then taking on board the cassette comment I agree that the change could/ should/ would be minimal(ish)


    I run 32:16 (52″ gear) on a 26″ bike with large hills (yes sometimes I have to walk)
    I also run 35:17 (60″ gear) at work where it is flat with some shallow climbs or short steep stuff. I run (fast shuffle) the short steep stuff when I can’t climb it but that’s deliberate. Essentially the 60″ gear is great for this area and I don’t spin out. While it had cross tyres on making the effective gear smaller it got a bit too spinny in places as there are quite a few bits of tarmac I use.
    Play with this

    I’d say go one tooth at a time and accept the extra costs. Although ask your friends and they might have cogs you can borrow.

    I’d change to a 33 on the front personally – also Midlands based. I run 32-16 on a 650 and can climb everything locally except Bardon Hill.


    We are all different, just depends on your riding areas and compromise to suit. Otherwise you back to a geardangular.


    I need the advice of any die- hard singlespeeders!
    I’m currently running 32-18 on a 29er for Midlands based riding.
    TBH the gearing is generally ok but can feel a bit ‘spinny’ on the flat, so far for my riding the gearing has not been an issue climbing
    As I don’t want to buy lots of rear sprockets how much increase of effort is there by dropping 1 or two teeth from the rear cog?
    I.e. if I drop one tooth to a 17 will I really notice or would 2 teeth mean my legs fall off?

    I prefer to have to smash up hills and collapse at the top or dismount and run up them, than the frustration of spinning out on the flat.
    I’ve found 36/16 excellent on my hardcore hardtail and find that if it’s too steep to ride then generally my geared mates have dismounted before me anyway.

    QTF. I use 38:15 on a 26″ cos I live in the (mostly) flatlands, I’ve ridden NyA 32:17 and I nearly died 🙂 Got round pretty quick though.

    My rule of thumb is you can always find a few more revs out of your legs but never an extra ounce of grunt when you need it.

    So I gear low.

    I’m just getting into it and have two gears on a 26″. Ride around Bham. 35 x 17 for local rolling routes and 35 x 19 for Wyre, Cannock etc. 35 x 17 is perfect for my local rides but would probably kill me at this moment in places like the Wyre.
