The creation of the XLR8 Sentinel saw us mix a high performance BMX racing tread with a hybrid/city tyre. We wanted the very best tread possible for grip on all surfaces and also with the ability to disperse water that was second to none! The XLR8 Sentinel grips fantastically well on tarmac, concrete, gravel tracks and compact dirt all year round (although not suitable for snow or compact ice). The tread also wraps around to the shoulders of the tyre giving excellent grip even while cornering. This gives our hybrid/city customers the peace of mind to ride on most surfaces all year round. The XLR8 Sentinel also has an amazing 5mm puncture defence layer (PD) under the tread (4mm on the 25C version) which is specially designed to keep nearly all sharp objects out stopping potential punctures. The 32C/35C & 38C sizes come with our reinforced sidewall defence (RSD) and the 28C size comes with extra puncture proof layer that wraps bead to bead (RB2). The carcass of the tyre is 60tpi giving is good flexibility and grip, plus, for extra visibility all XL8R Sentinel’s come with a reflective stripe on the sidewall.
