|   Disc hub question | RL
Jan 7, 2004 6:42 PM | | I have a question that hopefully someone could answer here. I am currently about to purchase a new disc wheelset, and I am going to use my other for road training. My question is, on my Bontrager Racelites, I believe those are Hugi 240s, and what I am wanting to do is easily change wheelsets, from a set with road tires, to a set with knobbies. On the new set that I have built do I have to use the same type of hubs so that my disc rotor is not off when it sets in the pistons. Id like to get some Kings, but I am worried that if the rotor is off just a couple of millimeters that it will rub. Thanks in advance. |

I suggest you pick what ever hubs catch your fancy without regard for what you're riding now. Get a handful of shims, which can be as thin as 0.2mm thick, and shim out the rotor on one of the hubs to match the offset of that on the other. Wheel changes will be easy as pie. |

Here is the kind I have in my shop;

It may seem a little extreme, but you can't even imagine how many time this stuff has came in handy. |
