Two new knobby WTB gravel tires bring large volume and plenty of grip to Road Plus, and the ever-expanding crop of 650B gravel bikes. Blurring the lines between gravel & proper mountain bike tires, the new WTB Venture and especially the new Sendero offer more confidence-inspiring grip to head further off-road on your dropbar gravel bike.
WTB expands Road Plus with Sendero & Venture gravel treads
I might argue that WTB is the reason for so many great 650B gravel bikes on the market, because their high-volume 47mm tubeless Road Plus tires made it possible to roll fast and still get grip for mixed surface road, gravel & dirt riding. But if you wanted to really leave hard surfaces behind Road Plus had still been deferring to the proper tread off wider 27.5″ mountain bike tires.
I’ve been a huge fan of WTB’s 650B x 47mm Road Plus tires since I rode through the winter on a set of Horizons. In the meantime WTB added a bit more grip in the 47mm Byways. But in my mind it was unfortunate that they dialed the width back to 42mm for the proper knobby Resolute in the interest of fitting muddy tires in gravel road bikes.
WTB Sendero 47 full knobby gravel Road Plus tire
The new Sendero fully leaves the idea of riding pavement in the rearview mirror. Developed to take on the tough gravel events like the Grinduro that mix gravel with technical trail sections, the Sendero is the tire for riders that want to push the limits of their 650B gravel bike. the perfect tire to send it for riders who think that anything with fat tires & disc brakes is a mountain bike.
WTB says the new tire still mixes drop bar efficiency and mountain bike levels of control. With Dual DNA rubber compound harder ramped center knobs keep rolling resistance under control, while more grippy openly spaced outer knobs dig into wet & loose terrain. Sticking with the bigger 650B x 47mm Road Plus casing, this tire might be a tight fit in some gravel bikes if the trails start to get muddy, but I personally welcome the extra volume.
