* We asked a bike team tested the new hubs for more than one year, and meanwhile we did some modifications.
* TR-003 hubs are with 75T ratchet which make the engagement very fast, so they perform the best when climbing.
* ECC bike hubs are used Japanese Multemp professional liquid grease --- high lubricity.
* The gorgeous anodized surface won't fade even in 170℃ high temperature baking for 7 hours.
* Easily convert between axle configurations with side caps change, tool free.
* ECC hubs are popular for the high quality & fast engagement and lower price.
- The teeth parts are made of CRMNTI material, using cold forging forming technology and CNC five axles precision machining process. Imported high-end heat treatment equipment for hardening treatment.
