Tufo Flexus Dry Plus is a cyclocrosstube intended for dry, hard surfaces. You can also use the Flexus Dry Plus on frozen ground.
The tread is equipped with low, small studs to keep the rolling resistance as low as possible. On the shoulders of this tube are a number of higher studs placed, for extra grip in fast corners.
The Flexus Dry Plus has the same tread as the normal Dry Plus, but the carcass of the Flexus version is a lot smoother, which makes the tire roll better and gives it more feeling. The carcass of this crosstube is made up of a very smooth 315 TPI section under the tread, while the 210 TPI walls are just a bit stiffer, which ensures more firmness of the tire at an impact.
Tufo Flexus Dry Plus is a light, smooth crosstube with very good puncture protection.
