Curve

Curve: stock cockpit data

64 values missing in 7 of 7 models. Database as of 14 Nov 2026. Angle and reach are usually the same across sizes, so enter them once. Anything shared by several models can be copied.

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 Curve 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

Have it in a spreadsheet? Send the export or a price list with the spec, just as it is, to [email protected]. I’ll copy the numbers across myself. Don’t have them at hand? Send the link to a colleague in R&D or service.

Not sure? Put a question mark after the number, like 100?, or explain in the note. You can paste a whole row from Excel in one go.
