A solid 5mm rim sidewall helps minimize the risk of impact damage by broadening the contact point between a sharp or square-edged object and the rim and tire. This also allows riders to forgo heavy tire inserts, which means less unsprung weight for better suspension performance.

E-TRA 29
Current price:
Sharing the durability and efficiency of the TRA WheelSystem, the E-TRA WheelSystem features E-bike optimized hubs with a heavy-duty steel axle and cassette body, built for the rigors of E-MTB.
Points importants
Featuring race-proven durability and efficiency, the new TRA boasts a hollow 5mm wide rim edge design for added strength, a reduced risk of pinch flats, and lower tire pressure for more traction and control. Lightweight alloy rims and a 72-tooth hub help maximize power transfer and get you down the mountain faster.

PUNCTURE PROTECTION
To simulate a pinch flat in the lab, a sharp, square-edged block is pressed against the tire until it hits the rim edge and punctures the tire. In test after test, the TRA WheelSystem was shown
Lab tests simulated pinch flat scenarios by pressing a sharp, square-edged block against the tire until it hit the rim edge and punctured the tire. In test after test, the TRA WheelSystem withstood the highest impact forces without flatting, outperforming previous generation TRA and other top wheels in the category by up to 44 percent.

MORE TRACTION
A broad 30mm inner rim width and robust 5mm sidewalls allow for much lower tire pressure, giving you better traction and control on rough, technical climbs and descents. A low 21mm rim depth further improves compliance and ride feel.

INSTANT ENGAGEMENT
The combination of a lightweight carbon rim layup and industry-leading 72-tooth pawl driver results in rapid power transfer as you pedal over obstacles and accelerate out of corners. In the rear, an oversized drive-side hub body bearing, axle and ring nut combine with enlarged pawls to increase stiffness and durability.

E-MTB OPTION
The E-bike specific E-TRA WheelSystem shares the same features and technologies but with an extra-strong steel axle and driver body on the rear hub to handle added forces and torque.

Technologie
Dynamic Balanced Lacing
Conçue pour fournir un effet de levier supérieur sur le rayon tracteur et inférieur sur le rayon pousseur, la technologie DBL maximise les performances des roues lorsqu’elles sont en mouvement en veillant à maintenir une parfaite tension des rayons, pour une rigidité au pédalage et des performances de freinage optimales.
Hookless Rim Design
La conception sans crochet de nos jantes leur permet d’être plus solides. La largeur interne de la jante est augmentée, ce qui permet d’augmenter le volume d’air dans le pneu qui travaille mieux, offrant plus d’adhérence et de contrôle. La tringle du pneu n’étant pas contrainte par une gorge, la jonction pneu-jante offre un profil plus lisse et plus aérodynamique. Un véritable atout pour la performance.
Wide Guard Technology
When your wheel hits a sharp or square edge, especially at speed, pinch flats and rim damage can occur. Wide Guard technology minimizes this risk by broadening the contact point between the rim and tire with a solid 5mm rim sidewall. That means you can skip the heavy tire inserts to have less unsprung weight on your bike and allow your suspension to perform better. The wide sidewalls also better protect your wheel from big impacts, reducing the possibility of rim damage.
