ethirteen Grappler Race Alloy e*spec Enduro Rim Info
Grappler Race Alloy e*spec Enduro Rim is engineered specifically for the demands of full-power e-bike riding, where higher speeds, greater system weight, and repeated impacts place extra stress on wheels. Built around a reinforced e*spec design, this rim delivers the strength and stability aggressive trail and enduro e-MTB riders rely on—without sacrificing ride quality.
The rim is constructed from 6069 alloy with welded joints, creating a durable foundation that resists deformation under heavy loads. A 30mm internal width supports modern tire profiles from 2.3” to 2.6”, improving sidewall support, cornering confidence, and traction across varied terrain. The result is a wheel that holds speed, tracks precisely, and stays composed when the trail gets rough.
A low-profile rim height contributes to a more lively, responsive ride feel by increasing compliance and reducing trail chatter. Compared to standard analog rims, the e*spec version features targeted reinforcement to handle the added forces of full-power e-bikes, with only a modest weight increase of approximately 50–60 grams.
The Grappler Race Alloy e*spec Enduro Rim is tubeless compatible with a hookless bead, making it easy to build a modern tubeless wheelset focused on grip, durability, and reliability for aggressive riding.
