Somnatash's chic Brompton + front Pantour hub pics!

On behalf of our revered German friend I'm posting some pics of her Brompton. It also includes some interesting pics of the Pantour hub mod on the front and the 8 Speed Sturmey archer hub mod on the rear. Finally I hope Somnatash forgives me for posting her posing in her matching outfit lol!

Somnatash's bike is called "Asphaltblume" a tarmac blossom. It ceratainly is one of the most unsual and most chic Bromptons I've seen. Congrats Somnat you certainly have very discerning taste in colour and bike parts!

Hi mulleady, oh, huuu, thanks

Can you convert them smaller please?
Also I feel a little ashamed that you made extra thread, I thought into the "name you bike thread" . Huuu, well, but nevermind, thanks a lot.

With the last pic I wanted to show how to improve rolling ability with a brompton: One has to mount roller (ez-Wheels) a rack and a teleskopic seatpost. Then, by leaving the lower-seatpost-part allmost down, the bike is still "secured" by the seatpost and the bike can be grabbed without unfolding. It is a manner to roll the brommi which does not take so much space than to roll it with the handlebar post and, in the long run, the little plastic clamp which secures the brommi folded gets stressed when rolled with the handlebar up.

The extra detail is good for anyone looking at hub mods on a Brompton. Anyway, it's a beautiful bike and worth seeing in close-up.

8 speed and Pantour! That must be a nice ride. Beautiful bike!

Question: How many teeth does the rear cog have? Looks like more than 14t...

The rear cog has 19t. As you can see the chainwheel is small 33t. It is quite low geared like that, I am almost always in the 6 or 7 gear, but having a steep hill on my commute and quite new to cycling long way and regular its okay to start with. I also need the granny gear.

But there is an issue with the small diameter chainguard. When folded that guard is about 1/4 inch too small to press against the frontwheel-fenderstay. This would be better since then the frontwheel is stabilised between the chainguard and the hook which rests on the rear triangle. My frontwheel has slight lift and right play when folded. So I probably change that when I get - hopefully - fitter

Very nice mod. I think there should be streamers on those handlebars though.

Yeah, I planned to fit them later anyway. They look better when waving in the wind while riding fast... I told you about the granny gear

Did you have to expand the rear triangle to get that hub on? Any special parts needed to be machined?

The Sturmey Archer 8spd hub is the only internal gear hub (other than the original hubs that come with the Brompton) that can fit within the dropouts without widening the rear triangle.

The gear change cable support - does that have to stick upwards like that due to rear triangle spacing issues? That would be mounted so it sits horizontally.

Yes, upwards for spacing (clearance is very tight and the rear triangle would be in the way as it goes diagonal inward, even like that one has to modify the gear cable support a little - cut a curve) and also cable routing which is very crucial while the fold. At least others have it also sticking upwards, see:

The last pic shows a brompton modified by Ben Cooper from Kinetics Glasgow. That's where I got mine btw. If you use the photo, he wants his name to be added:

I guessing precisely because of that. It has already had some unwelcome responses... should have cut off even more.

Boys...get your minds back to the bike, I've found them less temperamental Just joking

Maybe move that front QR lever away from the fork in case it rubs?

Hello,

Note, they sell Schrader to Presta valve adapters - these are collars that allow you to use a tube with a Presta valve in a rim made with Schrader hole. This is different to the screw-on brass adapters more commonly sold next to the cash register in a goldfish bowl.

Okay boys, go ahead as you like but I will answer to the bike comments only

The cranks are Truvativ Isoflow 175mm SRAM Dualdrive, single ring 33t. The bb was also swapped. Actually a lot of cranks can in theory fit on the brompton-bb that have a square tapered axle but most time one will need to mount a longer bb even with a single ring (the brommi-bb is 119mm)

The pedals are detachable MKS EZY MTE (Dahon sells them also) on both sides. See review here for example:
https://viktikit.blogspot.com/2007/12...zy-pedals.html
I plan to modify that into one side detachable only and to add leather straps.

I don't like/need the QR anyway - I hate to fix the bike by the street - that's the plus with a brommi. I have a flat then I hop on a bus or even taxi and later fix it at home with a cup of coffee. So the QR has has to go, I will swap it for a SON axle which fit perfectly and is even lighter. But you are right - one better puts the QR a litte bit to the backside, then it does not rub or interfere with the folded steering-stem.

Thanks Silverexpress for the info with the valves!

How well does the Pantour hub perform?

I dodge the bumps and ruts, but I need to get rid of the small vibrations.

Does the QR come with the Pantour? I do not want the QR.
