I recently purchased a set of these wheels and so far I am impressed. I put on a set of WTB Mutanoraptors and set them up tubleless and I am riding faster on the climbs and faster on the downhills. My only complaint is that when I put sideways stress on the wheels on say a corner, the wheels flex and rub against the V-brake pad. I have let out some of the brake cable and it still rubs. When I grab the wheel in my hand and give sideways preasure it flexes more than I would like. So, can I tighten the spokes and get a stiffer wheel? How much is too much as I don't want to break my new wheels? Anyone have a similar experience with Crossmax wheels?
