I got a chance to race my singlecross today. The course was not very technical, having said that the bike handled well. I ran the bike completely stock, heavy wheels and tires and all without any problems. When I got home I noticed that the rear wheel was rubbing and needs to be trued. I wonder how long I was racing with the brake rubbing?
Here are some more random thoughts...
With some race wheels and tires the bike would be significantly lighter. I don't have another rear wheel with a singlespeed freewheel. I was gonna put on a different front wheel on to race but I was too lazy to mess with the brake last night so I decided to leave the stock front wheel on. Then I figured why change the rear tire either.
I weighed the front wheel, 1005g with rimstrip and without the skewer. The skewer was 94g and the tire was 437g. Just swapping the front wheel you could easily save more than 400g (almost one pound).
It's a solid bike, I'm happy with it. I talked to a couple of other guys with the same bike and they're happy with them. I noticed that they have swapped brakes and gearing. I'm not close to the fastest guy out there and the stock 42x18 gearing was a little tall for me. A 42x20 would have been better, especially on the last few laps.
Overrall I'd give it a thumbs up, though I'd like to get some lighter wheels.
