Upgrade your ride with the Ibis Send 1 and 2 bicycle rims, a refined evolution of the acclaimed S35 model. The Send 1 rims feature a sleek, box-shaped bead wall design, while the Send 2 rims take it a step further with reinforcing ribs beneath the bead seat, adding just 45 grams per rim—lighter than many tire inserts.
This innovative bead shape ensures a broad, stable contact point with the tire, effectively preventing pinch flats without slicing the tire sidewalls or adding unnecessary weight. Constructed from 6061 aluminum, both rims offer a minimalist section height of 17mm, providing an ideal balance of strength and lightness. The 5mm spoke offset enhances wheel strength and alignment, and the rims are rated for a maximum pressure of 40 psi. Backed by a seven-year warranty, the Ibis Send 1 and 2 rims deliver durability and reliability for all your cycling adventures.
