The Reserve 48 GR front rim runs a 48mm profile, shallow enough to keep steering input predictable when crosswinds hit at gravel racing speed. Hollow Hook construction achieves the 30mm internal and 44mm external profile without adding rim weight, so tire support and aero shaping don't cost strength or add heft. The 24-hole rim uses external nipples and standard 12x100mm spacing, a straightforward build for anyone lacing up a custom front wheel.
What Our Gearhead® Experts Are Saying:
"The shallower 48mm profile earns its keep on exposed gravel sectors, where a deeper front rim starts fighting crosswind gusts for the steering line. I trust this rim to stay put through washboard and switchbacks alike, without needing to wrestle the wheel back on line."
