Challenge Grifo TLR folding tyre

The gravel and cyclo-cross tyres, top quality, now available in a tubeless-ready version. The multiple world champion tyre in cyclo-cross: specially developed tread pattern. The right choice for professionals and frequent riders. Incredible grip with very low rolling resistance.

The Gravel Grinder Race is the all-round gravel tyre. It is therefore particularly at home on long stretches of unpaved trails. But this durable tyre with puncture protection insert also performs well in everyday use. The flat tread keeps rolling resistance low, whilst the higher side knobs provide the necessary grip in corners. The folding tyre features a 120 TPI nylon carcass and aramid puncture protection, an additional layer of high-strength fabric between the carcass and the tyre to reduce the risk of punctures.

• Road bike tyre 33 mm x 622, foldable
• Casing: 120 TPI Superlight nylon
• Aramid puncture protection
• Tubeless ready
• Tyre pressure: 3.5–5 bar

TLR Series Vulcanised Tubeless Ready with Nylon Superlight casing

• Vulcanised tyres made from natural rubber offer excellent value for money and high durability, albeit at the expense of comfort and performance.
• Nylon is a carcass braid available in three main thread counts – 33, 60 and 120 TPI – and is wound around a steel or aramid bead. The nylon mesh is dipped in a bath of butyl rubber and then calendered between large steel rollers, compressed to produce the finished carcass. In bicycle tyres, nylon offers a first-class cost-benefit ratio thanks to its low price and comparatively simple processing.

Tubeless-Ready

• Perfectly suited for use with tubeless systems: no inner tube, strong puncture protection and high efficiency.

Vulcanised synthetic rubber

• To combine a long service life with good riding characteristics, synthetic rubber is boiled and hardened. The result is Challenge’s Vulcanized Clincher range: smooth-rolling tyres with high grip and good comfort at an affordable price.
