Trying to build up a light hardtail bike for my 11 year old (4' 6" and 65 pound) son using the frame his sister has outgrown. Son rides a variety of trails that include rocks and roots. One of the wheelsets available at the lbs is WTB Laserdisc XC with Shimano XT hubs. (Another wheelset they have they can offer a deal on is Bontrager Rhythm Pro 26 TLR in the rear with Bontrager Race Lite 26 TLR in the front) On the side of the WTB rim it says it 25mm wide. We are hoping to pay $200-300 and this set, and the Bontrager set fits in that budget. Considering going tubeless. I think the set is under 2000 grams.

What do you think of these wheelsets? Are there other wheelsets we should consider?
