Storck: stock cockpit data

15 values missing in 8 of 8 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 Storck 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
