Folders! Foldable bicycles, minivelos and demontables

I love it where did the stem come from?

I bought it a few years ago from an eBay seller that offered custom geometry.

That is very nicely done, have you weighed it? And yes, what stem? Made a plate for the rear derailleur? How has the rear brake been attached?

It weighs 7.7kg with Ti spindle Speedplays Zeros.


The rear caliper is attached using a small mount that I TIGed together.



The rear OLD is 112mm on these bikes. I do a modification to a 130mm Hubsmith hub which uses 7/10 cogs. Then I shift the SRAM Rd with a Campy Xenon 10sp lever. The adapter plate I made out of 6mm 6061 plate. You can see small adapters that I had made to mount a rack to the abandoned V Brake mounts.



The carbon fork is preloaded then this Problem Solvers locking spacer is snugged up before tightening the stem mast.



I use an offset ring to put the chain line in an acceptable location.

I hope that explains a bit of my madness. This bike is kind of half of a good idea. It fits and rides nicely, but the fold is a bit of a gong show.

I like that. I would happily take it for a ride

That stem is the star of the show really

Here is another before and after. Same frame type. This is a bike I ride daily. This one uses a SA 5 speed hub. I stuck with 305 wheels for this build. THIS one folds properly.

It took a while to find this photo. This is the first folder that I messed with years ago. It was originally my daughter's bike

I built the wheels using a Crupi BMX freehub. It was just phenomenally, incredibly and outlandishly LOUD.

NIce work. 7,7kg is quite an achievement. If you like, show a pic of it folded. It is a folder thread, after all.
