GT Tachyon

One of the newest trends is the "gravel grinding bike" - it is a mix of a racer and cyclocross bike with emphasis on the road bike but having discs and slightly fatter tires than a CX bike.

It is a bike that is totally unnecessary but if there where no new stuff to buy the industry would fall over and die so you need to have a gravel grinder besides your snow bike in the future (you read it here first).

Just to prove a point, everyting old is new again, check out this vintage Tachyon.
