The threshold guardian reimagined.
GRL Series’ Asymmetric Evolution Platform – born from our RA lineage – wields widened inner widths (24mm mini-hook /25mm hookless) like a cartographer redrawing terrain maps. Three decisive profiles (30/40/50mm) cut through the schizophrenic demands of modern riding, where gravel’s grit collides with road’s vanity.
Here’s where brands weaponize choice: the V2-V3 layup duality offers precision instruments for weight-critical adventurers and aero-obsessed tarmac hunters, while our value-engineered V1 foundation (explored in BASIC RIMS) anchors high-volume OEM dreams.
No bead sermons – just cold, clean carbon options whispering to tire anarchists.

Rim Height
In cycling, rim height significantly impacts the aerodynamics, agility and weight of the wheel. The general principle is the higher the profile of the rim, the greater the aerodynamic advantage; the lower the profile of the rim, the greater the response and better the handling when cornering and changing speed.
