Product features
Ultimate trail traction
XR5 blends an aggressive tread and lightweight construction, making it perfect for the rider who prioritises traction in a lightweight trail tyre.
Inner Strength
The XR5’s Inner Strength casing is made of a lightweight nylon insert that provides strong, supple sidewall protection for added tyre durability.
Aggressive tread
A robust centre tread delivers great braking and all-around traction while the more aggressive side knobs add cornering bite for when you really lean the bike over.
TM-Grip compound
Our proprietary TM-Grip compound is designed for traction. Soft dual-compound bites into corners and with added durability on the centre tread. 120 TPI construction gives you great tyre feel.
Tubeless-ready
A properly set up tubeless system lets you run lower tyre pressure for better traction, added confidence and a smoother, faster ride.
30-Day Unconditional Guarantee
If for any reason you’re not satisfied with a Bontrager or Trek aftermarket purchase, return the item, along with the original sales receipt to the original place of purchase within 30 days for an exchange or refund. Think of it as a 30-day test ride.
