BikeCAD Feature Request

Slowly, I've been learning how BikeCAD (and bicycle design) works, and who the suppliers are. Turns out, there's a number of dropouts avalible from Allotec but not the one I purchased from Frame Builder Supply, the Allotec C24-2.

(Figuring out this was an Allotec dropout was a mess!)

I noticed you've recently added other dropouts, including some from Allotec, so if you're able to add this one as well, that'd be amazing Brent! Especially with the dropout's weird geometry, post mount placement, and accompanying C24H hanger.

Allotec C24-2

It wasn't long ago that Allotec was very quick to send any CAD models I asked for to include in BikeCAD.

Unfortunately, they have recently found counterfeit versions of their products on the market and in an effort to combat that they now insist that anyone receiving files from them must sign an NDA. Anyone signing the NDA must commit to only using the files for their own purposes. Although, adding designs to BikeCAD is my own purpose, I think this goes against the spirit of the NDA.

The last I heard from Allotec about this was March 2025. A few days ago, I emailed to see if anything has changed with their policy and I have yet to hear back, so I'm guessing I may not be able to help you out with this. I'm glad I was able to include the Allotec C23 dropout before this policy came into effect, you may find it a near match for much of your design work.

I'll let you know if I hear any news on this from Allotec.

Shame, but completely

Shame, but completely understandable on your end. I suppose I might break out the calipers and try to get the exact measurements since the C23 is close, but the fender eyelets would imply the dimensions are still significantly different. Still, not a terrible idea in the meantime.

Looking forward to any news, if it comes. :)
