Bontrager's Rhythm Comp TLR Wheels are a serious upgrade for any trail bike. The tough, tubeless-ready 6061-aluminum rims, sealed-bearing hubs, stainless-steel spokes and locking aluminum nipples mean that these wheels ride great and last through more than their fair share of big epics. The 28mm-wide rims provide a nice tire profile for more contact with the ground with less squirm and better bite.
