Why We Like The TR 309/289 XC 29in Boost Wheelset

With the aggressive cross-country courses riders are seeing today the Reynolds TR 309/289 XC 29in Super Boost Wheelset is built to define the ride. More often than not we find ourselves needing more grip and less rolling resistance on these ultra-tough XC courses. The Reynolds is tailor-made and designed, with a wider front rim for traction purposes paired to a narrower rear to keep rolling speeds high. TSS PR3 material on both the front and rear rim also improves impact strength and durability for those of us who are hard on our wheelsets.


  • Aggressive XC rims hold up race and training abuse
  • TSS PR3 material on the front and rear rim improves strength, durability
  • Front 30mm internal channel and low profile for precision steering
  • Rear 28mm internal channel and low profile for increased comfort
  • Reynolds TR MTN hubs feature 10-degree engagement, 3 pawl
  • Item #REYE00Q
