Brompton owners

From the page you linked:

When fitted to an S type stem the height position is the slightly
above an M type. – Use M type cables.

Good stuff, welcome to the club

thanks

This is wrong.

The bars are designed, by JK to convert S to M. It’s not slightly above, it’s the same height.

Therefore you need M type cables.

Sadly the description has been changed since I wrote it.

H type cables are too long.

I’ve got a Brompton saddle and S Type bars in silver gathering dust if anyone has any use for them? Both in excellent condition.

£20 each posted from Edinburgh (or £15 each if you can collect) sound fair?

My error, I suspected you had written it, but didn't know it was wrong. @chokalateboywonder as above, but you do need longer cables

Tips for a perpetually squeaky Brompton? I feel like I've tried everything except the bottom bracket - ironic that. At first, I thought it was the Brooks saddle but I've been using a Charge Spoon for around a year now. I also thought it could be the suspension block, but I replaced that and made sure the axle had a good dollop of blue Mobil grease. Only happens while pedalling too, hence the BB suspicions. I'm using Shimano T8000 pedals, and seriously doubt its them.

What Brompton do you have? Mine sometimes squeaks from the cogs/chain tensioner after lubing the chain. Maybe try spinning the cranks without the chain attached to the chainring and see if it does it then?

What’s the benefit of doing the 5 speed mod on the 4speed? Do you gain an extra higher gear or lower gear?

Bike hasn’t left my side since I got it. Really enjoying it.

Highlights from first week of Brompton ownership have been. Rushing to collect records (pictured). Being so drunk I couldn’t fold the thing. It was like playing an accordion. Finally, being told off for not folding in a supermarket. It’s been wild.

Probably better to get a bigger chainring that adding a 5th cog.

S6L. Defo not them. Chain gets cleaned and relubed, also relubed my chain tensioner about a year ago, and replaced it more recently. Cranks/chainings could be contributing to the problem too though.

The shop suggested this too. Would like a bit more top end speed. 50t is what it came with. Does going 52t make much of a difference? Tried looking at a gear calculator but I have no idea.

It seems I managed to lose 3 of the 5 chainring bolts on my brompton, before the whole drivetrain came to a grinding halt. Could anyone tell me if there's anything specific about the Brompton chainring bolts before I try and source them from my non-Brompton-dealer lbs?

I have some spare - yes I too have lost some over the years, and on other 1x bikes that use the same bolt type/size too. Maybe not enough torque? My SRAM chainring bolts normally have thread-locker on them, so I'm going to try that next.

Thanks but I'm regrettably not London/UK based any more...

The 4 speed Bromptons already come with an 11t high gear, which is the smallest the hub will take, so a basic 5 speed mod can only either make the lowest gear lower or maybe reduce the gaps.

If you want higher gears you need a bigger chainring.

Morning all. I shattered the plastic handlebar catch this morning in the -2 C weather when refolding the bike. Does anyone know somewhere near Stratford that carries it? Currently the nearest I can find is Condor or Balfe’s, and I can’t make the diversion easily. Thanks!

Hub Velo at the top of Lower Clapton Road.

Edit: Morning!

quick question, the (top tube?) hinge is MAD squeaky. Should I just smash in normal purple grease or is there a suggested substance for hinges

replace pin, right @sbbohr ?

I'd prefer to treat the symptom rather than resolve the cause if possible

LMAO.

I was thinking of converting my 2 speed to 3 speed using the external derailleur. It’s a 2013 model with the older “rabbit ear” shifter.

Am I correct I’m correct in thinking that I just need:

Friction thumb shifter (Sunrace M96)
3 cogs (repurposed from a 11 speed Shimano cassette)
11 speed chain
Thinner circlip

Anything else I need to be aware of?

Just needs a few drops of chain oil if you're feeling completely unfancy.
