That was a fixie.

They're Vertical dropouts all Bromptons are. .. so even more of a fools errand should get a Titanium rear dropout substitution welded in

dump the chain tensioner entirely. (lose another few ounces)

[MENTION=99345]mulleady[/MENTION] - I remember.. A nice day for sure. [MENTION=88907]mconlonx[/MENTION] - Handlebars are just North Road bars, fitted upside down with road tape [MENTION=197614]fietsbob[/MENTION] [MENTION=30891]jur[/MENTION] - yes was running fixed at time so no need for rear brake. Saying that - I'm running a duomatic style 2 speed freewheel now and have kept it one-brake which is fine if not entirely legal.. You have to run a tensioner or the chain falls off when folding or going over bumps (hinge centre is not same as BB centre so as rear triangle pivots the chain slack varies)

While going through the thread again I thought the bike in post #116 looked familiar.

I actually got to ride the mystery mini-tall bike this past summer at a cycling event in Tokyo. It was a lot of fun to ride.

With the same basic folding architecture, they seem to have done a better job with the handlepost fold than Anemos did with their Zippy.

Like a current production Bridgestone Moulton, perhaps?

Di Blasi R22

with one of the coolest folds in the business.

Uh - is that really a molded plastic (polyamide reinforced with glass fibers) front fork?

Citation for the fork? I don't see where it's specified.

That's not to say it couldn't work,there are some pretty tough plastics these days.

Di Blasi sez that some parts of the of the R22 are 'polyamide reinforced with glass fibers', and that's certainly what the fork looks like in the HD pictures on their web site. The fork is definitely molded or cast.

They've been in the folding bike business longer than almost anyone, so I'd be inclined to be impressed.

I have to agree, that is one of the coolest folds in the business.

Pardon me, i would like to post this bike if all you approve

here it is :

this bike was built inspired by this thread, so many thanks to all you for the inspiration

Very nice bike!

If I may make a suggestion, reducing the spacing between the mudguards and tyres, will give it a more integrated look. Or perhaps you have a specific reason for the space.

Off topic, I wonder what happened to smallwheeler? He has suddenly stopped posting here. I hope no harm has come to him?

I left space , so stuff the wheel picks up falls out rather than jamming under the mudguard .

Water sprays off the highest part , the center of the Tire, anyhow.

[MENTION=30891]jur[/MENTION], thank you. Yes you are right the fenders are a bit off because yhe kojak was just in. Previously i use roadcruiser tyres which is bigger. I need to re adjust them. Nice observation

Small wheels definitely look more in proportion than big wheels, don't they? What size wheels are these?

From the derailleur and disc rotors,I'd say 20".

edit: yep

Looks like 451s

According to the link above, yup.

small wheeled bikes have advantage of a tall headtube, so having a suspension fork actually not a total handicap in the road. i prefer rigid fork though :D

I'm with you on that, I also prefer a rigid fork and at the very least the conceptual added stability of the longer headtube giving more distance between headset bearings.

BTW, Nice bike, always good to meet a fellow Silvertip owner.

Speaking of bikes we like or admire, I started looking at the details of the Dahon Mu Rohloff. Sure, there's the equipment: Rohloff 14-speed IGH, gates belt drive, Magura hydraulic disc brakes, Ergon grips, etc., but I notice the frame, while in the Mu family, is specific to this model. It's got screw adjusted sliding dropouts, and I believe it's the first production bike in the world to have internal frame routing of the Rohloff shift cables. It's hard to tell under the glossy 'Agate' paint, but it looks like Dahon spent more time and effort on smoothing/flaring the welds of this Mu's frame as well.

I've been hearing from a few quarters that these newfangled carbon fiber frames and forks are sure to bring grisly deaths to their riders...for twenty-seven years now! But yeah, folding bikes do kind of lead rough and tumble lives, and besides, out on the cutting edge of cycle design/fabrication I been pretty impressed the last few years with what they're doing in hydroformed aluminum. But back to Ori: carbon fiber with the latest Shimano electronic shifting mechs - and it folds up!
