Frequently asked questions

What size GTR Team do I need?

It depends on your position, not just your height. The most reliable way is to compare the stack and reach of a bike that fits you with those of each size (from 515/373 mm in size XS to 602/399 mm in size XXL). The size finder on this page shows the closest size and the stem and spacers you would need.

What are the stack and reach of the GTR Team in size M?

Stack of 548 mm and reach of 383 mm, with an effective top tube of 540 mm and a head angle of 72.0°.

Is the GTR Team a racing or an endurance bike?

In between. In size M its stack-to-reach ratio is at percentile 44 of road bikes: neither very low nor very tall.

Does it have the same geometry as the Garda?

In size M, yes: same stack and reach. If one already fits you, the same size of the other will put you in the same position.
