    Bought some Halo Combat’s off eBay, and the rear is single speed. Any idea if I can convert it to take a cassette with something like this?

    Or will it not work?

    Hi,

    Juding from the photo’s which you put up in the main section i am afraid to say that that is a single cog hub only.

    The width between the flanges is too wide for it to beable to take a cassette and looking at the DMR website there is no option to convert it. Had it of been the free hub version then you would see quite a bit of a spacer either side of the sproket.

    Hope this helps. if anything you could use this wheel as a great winter training rim. you can get chain tensioners from ‘On-One’ and just run single speed. no more mud to worry about.

    Thanks for the reply mate. I think I may break down the wheel, get a different hub, re-assemble then pay for it to be trued, which should be cheaper than paying for a wheel build.

    Any problems with this idea?

    I am no wheel builder but cant see why you cant do that, dont think that there is any diffrence in the flange to rim lenth on a spoke apart from the obvious 24″26″ 700 etc.

    A mate of mine was going to have a go at building one there are a lot of youtube video’s on how to lace them up.

    The only problem would be having a some kind of jig to spin it on to see if it’s true or not, I’ve seen How to’s for wheel building and jig building on the net, I just don’t have the resources at my house (it’s a student house, and my tools extend as far as a shoddy toolbox).

    I’ll welcome the day when I have my own house with a shed full of manly things…like tools and drills, not Chipendales!

    The hub probably won’t convert. If the measurement between the flats which would sit inside each dropout is 135mm the DMR thing looks like it would extend this further.

    Worth dropping DMR a line to make sure.

    As for rebuilding I wouldn’t bother. The spokes will more than likely be the wrong length and for the cost of a cheap hub (say deore) someone like Merlin/Chain reaction will sell you an ok wheel for not much more.

    Or run it singlespeed (seriously) :0)

    I was planning on getting the cassette version of the DMR revolver. Would that take the same spoke length do you think?

    This hub’s in relatively good nick so I should get a fair bit for it on eBay, to part fund the new hub.

    Probably not as the dish on the drive side of the hub will make the spoke length shorter.

    The Flange diameter needs to be the same too. You might find the data on the DMR site or they will be able to tell you.

    I’ve emailed their tech dept to ask about it. You’re more than likely right though. Emailed the LBS too, see if spokes are included in a wheel build, though I doubt it. The wheel build only costs 20 quid though, so not too bad.

    Do it yourself. You don’t need much although the proper tools are much easier to use all you really need is a spoke key.

    look on sheldonbrown.com for wheelbuilding. It is relatively easy if you take your time and if it all goes pear shaped take it to the bike shop.
