Ultra lightweight Brompton

[TripleG]

How do I get a Brompton as light as possible? The only exception being the gears I need 3 to 6 gears. Look forward to hearing some comments.

Remove the saddle and seat post. Saddles are for lazy people.

Why do you need it to be light a possible?

Titanium Seat post , Ti front and rear , S bars, no mudgaurds, no lights, change saddle , do you really need 3 speeds, 2 speeds may do you with a lower/higher chain ring?

What he says.

In fact it describes my Brompton except I don't have the Ti seat post and I've got a Brooks saddle on it.

I'm very happy with 2 speed, I even considered single speed. It's a good way of losing some more weight if it's not too hilly where you are.

Also I believe that the Kojak tyres are lighter and faster than the standard Brompton Kevlars. I'm not sure about availability of lighter tubes in that size. There must be some Brompton Worlds participants on the forum who've been through all this?!?

Mine is a P6 fully dressed with dyno hub, Brooks and mudgaurds, but I'm ( so far just) resisting an urge for a S2X as a summer bike.

Here's my S2L-X...

The only other change recently is that I now have the firm elastomer, which does make it feel a bit more efficient and faster.

Apologies for the slight thread hijack!

Edit: Hmmm, can't seem to attach a picture?!?

Being an archetypal fat bastard, I had the uprated rubber bung from the start.

I live in Sheffield so not sure I'd get away with 2 speed.

 

[Rohloff_Brompton_Rider]

you've been beaten to it

Nice bike not sure this is off the shelf though and what does a normal Brompton weigh compared to this.

The weight in a 6 speed is mainly down to the 3 speed hub, there is no real penalty for the extra 6 speeds, apart from reliability.

Are there any carbon fibre bromptons?

not that i know of, but, there is a firm in america that makes titanium ones, last time i looked they cost about £14,000 iirc.

Is the weight saving honestly going to make that much difference?

Think of it this way - more weight to carry = more muscle you gain

Which = More weight! :-(
