Frequently asked questions
What size R5 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 500/369 mm in size 48 to 625/413 mm in size 61). 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 R5 in size 54?
Stack of 550 mm and reach of 386 mm.
Is the R5 a racing or an endurance bike?
In between. In size 54 its stack-to-reach ratio is at percentile 40 of road bikes: neither very low nor very tall.
Does it have the same geometry as the Teammachine SLR?
In size 54, yes: same stack and reach. If one already fits you, the same size of the other will put you in the same position.
