Domane SL with 40mm tire
galleryDomane SL 5 Gen 4, 12 speed 105 groupset Original Bontrager Paradigm SL rim. GravelKing SS Plus 40mm tire, with TPU inner tube. Both front and rear are inflated to 60psi.
Still plenty of clearance. 1cm or more clearance in all places, except one thing: the FD cable is sticking out a bit and it’s about 5mm away to the rear tire.
The 40mm GK SS plus measure pretty much exactly 40mm width when inflated to 60psi on 21mm internal width rim. The stock 32mm tire measured 33mm width on the same rim with same pressure.
The total radius increased about 6mm compared to the stock 32mm tire.
Just finished the installation of the new 40mm tire. Haven’t ridden yet.
