Bontrager Galbraith RSL SE TLR MTB Tyre

Galbraith RSL SE is an aggressive trail tyre that boasts incredible tread, sidewall and pinch cut protection into a package that's ready to roam the loam.

RSL SE Construction provides a durable 60TPI casing that's paired with sidewall, bead-to-bead and apex puncture protection. A trail triple-compound delivers the ultimate combination of grip and speed with a firm and supportive base compound to maintain rolling speed, a softer centre tread for braking and climbing traction, and even softer side knobs for ultimate bite in corners.

Named for Bellingham, Washington's iconic Galbraith Mountain, Bontrager Galbraith tyres pack in serious traction and protection for staying planted on rock walls, balanced on wooden features and ripping through challenging, variable terrain.

Galbraith's aggressive tread pattern keeps your grip locked in and packed with protection for loose, soft and techy conditions.

A robust 60 TPI casing features squarewoven nylon puncture protection from bead-to-bead, additional sidewall inserts, as well as butyl apex inserts for superior flat resistance from cuts, slashes and pinch flats.

A medium-firm centre rubber provides braking and climbing traction while soft shoulder rubber adds cornering confidence. An ultra-supportive base helps maintain a fast-rolling tyre.

A properly set up tubeless system lets you run lower tyre pressure for better traction, added confidence and a smoother, faster ride.

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.
