Through axle trying!

At present, We test a demanding GT-Roller Flex3 that corresponds to Through axle hub for realization.

The looks is so rough for prototype.

It roars, so the bike in movie is cylcocross.

But in reality it is silent.

The feeling using block tire on Flex3 is comfortable unexpectedly.

We advise that you use an only for rollers, in fat manufacturer does not recommnend.
