Problems can arise when using modern wheels because they are factory-fitted with QR (quick-release) skewers. While on geared bikes quick release fewer wheels would be a good thing on a fixed cog or singlespeed bike they're just not strong enough to hold the wheel in place under pressure. I didn't know this for a long time, and therefore spend at least two years constantly pulling my back wheel tight, more often than not in the middle of a commute.
Another reason some people prefer not to have QR skewers is that in theory your bike wheel is a lot more nickable with QR. I understand this logic - why would you make life easy for a thief?
I did some research into how to replace a QR with a straight bolt and a lot of the answers came back suggesting removing the axle, changing the cone bearings, and many other complex things I didn't want to have to get involved with.
Eventually I found the Halo hex-nut skewers, and that's more or less where this blog posts ends. The old quick release skewers slid out, and the replacement Halo skewers slid in. The conversation was ridiculously easy. I was particularly impressed that the Halo replacements even had a recommend torque setting. Nice! Now my wheels will stay in place and no bugger can nick 'em!
You can buy Halo QR replacement skewers at Chain Reaction Cycles...
I've included some photos of the conversion to give you an idea of what the new wheel nuts look like.
