I'm thinking of buying one of these for road use not CX:-

http://www.genesisbikes.co.uk/bikes/cross/day-one/day-one-disc

They come with an 18t freewheel and I wondered if it would be possible to change this to a 16t? My concern is the rear disc brake caliper might need adjusting if the wheel has to be moved further back to allow for the smaller freewheel?

Any knowledgeable advice would be appreciated.

    I don't have any experience with disc brakes but can't see it being a problem.

    You'll need to adjust the position of the wheel in the horizontal dropouts anyway, as the chain stretches over time, to maintain sufficient tension.

    If anything you may need to shorten the chain slightly with a smaller sprocket.

    Personally I'd ask the shop I was buying it from to do the swap - might work out cheaper than doing it separately after purchase.

    The disc brake mount will be adjustable as you need to be able to adjust for chain wear / different sprocket sizes etc. Simply slacken 2x 5mm Allen screws, reposition brake and retighten. You may need to take a link out the chain.
    Make mine an Italian, with Campagnolo on the side..
  • Thanks both for your replies. That is what I thought but just wanted to be sure before purchasing.

    Does anyone out there own a Day One Disc and if so how do you like it? I was planning to fit road tyres (probably 25s rather than 23s) with SKS Chromoplastic mudguards and wondered if anyone had done this? One concern is that with say 25 road tyres on rather than 35 nobbly's there will be a large gap between the tyre and mudguard?
  • It definitely needs a 16t. I can sort most stuff out but since this is essentially a BMX type job I got the shop to stick the 16t on and take out the link.

    Mine was a Day One Cross rather than disc. The brakes were hugely irritating on mine so this will be so much better.

    As stated, BB7's adjust very easily. Worst case is you'll end up removing or adding a few washer spacers.

    Not if you choose the right ones. So get the type that allow up to 28c.

    Wut?
    The chain wears, but unless you've got rubber links, it won't stretch.

    The chain gets longer. "Chain stretch" is a common enough term and we know what it means.

    "Stretch": defn. To become lengthened, widened, or distended.

    You only need two tools: WD40 and Duck Tape.
    If it doesn't move and should, use the WD40.
    If it shouldn't move and does, use the tape.
