Thanks @friendlymoose most of my previous cycling stuff went in the OCD community it was a while back when I was cycling in the Philippines. On my Baby, that was a very modified/upgraded small frame Marin Team CXR with competition FOX folks. Full Shimano XTR groupset,dropper post, carbon bars and Ti bolts every where. 7.5kg It used to fly. When I left the Philippines I gave it to my cycling buddy out there as I knew he’d look after it,
The spray on the cloth was from the caliper on my TT another project.
Bicycles with different size wheels have been round for quite a while I have a retro lo-profile Time Trial bike in the garage 650C front wheel and 700C rear its from the 70s small frame and allowed a better aero position. It’s very quick on the road.

Stay tuned and I’ll post the e-bike mods when all the bits arrive.
