Bent rim

If the brake surface is damaged I recommend tossing it. Last year I bent mine on that same curb in the same race, repaired it, and a couple months later BAM the brake surface exploded off the side of the rim.

I had a blast at Cross Crusade today. Unfortunately, my rear wheel didn't. Biffed one of the curb hops and managed to bend my new OpenPro. >= ( Anyone know of a shop that can fix this kind of thing? Can it be repaired or is the rim hosed? Please tell me it's not...

I have done some re-straightening of rims. Some shops may have a rim puller thingy... I have seen some before somewhere. They pull the hop out of rim. But this is very hard if not impossible to do. There is not much reference to go on while you do it... You can kind of do it by mark carefully on the rim, then loosen the spokes in the hop area and try to pull / permanently re-bend the rim back out. and then re-tighten the spokes and check how you did. Its typically much easier to simply tape a new rim to the wheel and transfer the spokes over. Now i have been sort of successful using wood blocks and just the right amount of bending to get rim pretty close to straight again... But the problem is, its always hard to know where you are at until you start building the wheel. I have used such a rim in a track or front or single speed wheel where one doesn't need to worry about the low tension on the left spokes for the dish. that is, with symmetric wheels you
have more tension to play with and so can simply use the spokes to get the wheel true. No you can NOT use a Tensionmeter to build this wheel, you just have to true the wheel, some spokes might be lowly tensioned, some highly tensioned. Despite what "experts" may tell this is ok and the wheel will hold true as long as the lowest tensioned spokes are tight enough to not go slack (when the spoke goes slack the nipples tend to loosen and then the wheel goes out of true... This why some wheels (depending...) kind of need thread lock on left spokes on a 9 or 10 speed wheel...) and the tightest spokes are not so tight as to pull out of the spoke bed / eyelet... BUT regardless the wheel will never be perfect. Now it will probably be more then fine enough to ride with, the out of true or hop will be perceptible if you look, but not while you ride. so this might be a great wheel for the rest of cross season !
