i have a specialized allez frame that i want to make into a fixed!

i know its easy to change it to a single speed, just use spacers on the cassette, but is it possible to make it into a "proper" fixed?

wont the spacing at the back be too big to put in a fixed wheel?

thanks

    What dropouts does it have? If vertical, then you;re not going to be able to do it
    Carlsberg don't make cycle clothing, but if they did it would probably still not be as good as Assos

    Eccentric BB or hub, will do it, won't it?

    Most modern frames have vertical drop outs, but you can convert it to fixed using a White Bros ENO eccentric hub - try Sideways Cycles, Hubjub or Charlie the Bike Monger. I run one on my fixed conversion - a full carbon Battaglin race frame. It's a well-made pice of kit, but pricey at £125 for the hub.

    I run an ENO too. It works well.

    You have to be aware that the axle moves on a circular arc, so you may have to adjust your brakes when you set the chain tension. I found that down and slightly back was right for my chainstays and selected gears, so I needed to swap the back brake for a deeper drop version to reach. Some people report problems keeping the chain tight - maybe they have the hub set so that pothole impacts tend of loosen the chain?

    The current production ENO hub also uses a bolt on sprocket. That means that if you want a replacement or different sprocket, you are tied to the same stockists that sell the hub and what they have in stock at the time. Either that or plan in advance and keep your own spares.

    Yes, it is a dedicated sprocket but uses a unique spline pattern machined directly onto the body and held in place with a conventional lockring - pricey at £35 but it is an extremely well-made and likely to last many years. I have mine adjusted with the eccentric down and to the rear - any downward force will only increase chain tension.
