X-LAB: stock cockpit data
9 values missing in 6 of 6 models. Database as of 14 Nov 2026.
I’m Marcel Dobrocký, a bike fitter from Brno in the Czech Republic. On sedimi.bike, riders enter their riding position and the site works out which frames and sizes fit them. To do that for X-LAB bikes, I’m missing the stem length or angle and the bar reach.
These are figures you can see on the bike or read off the parts, nothing internal. Where I don’t know them, I use an estimate. With your numbers, the size is worked out from the actual build, and each value is marked ◆ with its source (manufacturer or dealer), with no name attached. Even one model helps. I check every value before it goes in. About sedimi
