Taipei Cycle Show

We will participated in Taipei Cycle Show in collaboration with Nexo tire this year too.
Our booth number is S0902.
Be sure to come!


Hello there!
We participated in CABDA this year too!
It was often said that “Have you exhibited last year, right?”,
so we felt GT-Roller began to gradually be recognized in the Chicago neighborhood.
We will continue to do our best to propagate our trainer abroad.
Thank you!


The leters patent

We obtained the letters patent for GT-Roller Q1.1 in US today!




Coming Soon.

It is not a speaker.

We participated in Chicago Bike Swap

We participated in the exbition that held by a local shop and a private person in the suburbs of Chicago.

The site is not so large as a gymnasium.
GROWTAC alone was from Japan.
The event is very local.
However, its attraction is coming to genaral user's attention.

In below freezing point Chicago where is in season of the indoor practice, especially our products were taken interest in.

The general cyclists tried our products more than a big events as Eurobike, Interbike.

Specially, The fully-equipped Q1.1 had a good retation.

We spent precious time for interchanging an idea to the cyclists in general at the local exhibition like this.


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.




The beginner on Q1.1

The report on CYCLE MODE 2016

And then our booth for testing GT-Roller was in full swing at CYCLE MODE that is the biggest exhibition for bicycle in Japan last month.

Thank you for standing in line for a long stretch of time.

Only a month left twenty -sixteen, GROWTAC first exhibited our products at EURO BIKE and second at INTER BIKE.
