Chumba

Chumba: stock cockpit data

I have what I need for all 4 models. Anything the customer chooses when ordering stays optional. 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. For Chumba bikes I have everything I need. Anything the customer chooses when ordering is optional. You’re welcome to check the values and correct anything that’s wrong.

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.

Send what you have

Feel free to send only part of it. You can add the rest another time.

I’ll only use your email if something doesn’t add up and, if you ask, to let you know once the data is on the site. I won’t publish it and I’ll delete it on request. Sending this commits you to nothing.
