We know that most people concern about rim brake, worry heat deformation problem, after test and test, we use thermal conductivity nano materials Graphene on the rim surface, almost can slove the problem, but we never stop develop new brake tech.

The newest brake tech is texture brake surface (TBS), it is one piece moulding, no painting on brake surface, it would has better brake effect, smaller brake sounds.

Now model 520-C1, 451-C1, 451-C2 and 349-C1 have upgraded to TBS brake tech, the other carbon rims will upgrade soon.

Thanks a lot for you to choose SMC Bike, we are try to be your most trusted friends.
