Brompton owners

No, they are too wide

Pity but thanks for the reply. Which in your opinion is the best mechanical disc brake for the Brompton? Will TRP HY/RD road disc brake calipers fit? I know TRP Spyre fits.

Trp spyre, due mainly to size.

Avid BB7 road S for the rear? Just looked at an obscure bit of the Kinetics website...and the TRP HY/RD will work at the front according to Ben but not the rear...so the choice is the TRP Spyre or the BB7 Road S for the rear disc brake.

Brompton has exhausted its 2020 capacity, 28 weeks wait on new bikes!

Lucky we have 150 bikes on order!

Lucky indeed...

I thought the 'new' Greenford factory was meant to allow for projected growth?

Been making loads of nhs bikes and cycling has gone mad....

I worked there in 2016 a few weeks after they moved in. At the time they had changed from running 7 days a week in chiswick to 1 much bigger production line 4 days a week.

They were fitting out a second line, at the time which (back of the envelop calculations) could let them make 150k/160k bikes a year. At the time they were making 45k bikes a year with an 8 week wait. The people who worked on the line preferred the 7 day working so I imagine they would try to run the factory 7 days a week before introducing the 2nd line.

You also can't increase your workforce overnight, sustainable growth etc and it takes time to train a brazer which is the real bottleneck.

Titanium triangle now on eBay, 99p start.

orders due after october probably cancelled...

oh...have I missed the boat then or will my order in a couple of weeks or so be one of the lucky 150?

your bike is confirmed, no issues!

If I do the S2L to 3 speed conversion, what are the shifter options?

I've got the 2017 type 2-speed shifter currently. Are friction shifters the only option?

Thanks for this insider knowledge.
I'm trying to remember when in 2016 the Greenford factory opened.
I'm often passing through Greenford, but normally one road over to the West,
so did not routinely cycle past the entrance to the industrial estate.
'7-day working'?
The production line never stops but the worker do a normal 5-on 2-off rotating shift?
Any idea how many (apprentice?) braziers Brompton were training up?

external 3 speed?

Yeah, the Bikegang kit basically

"best" is a sunrace M90 friction

'7-day working'?

Yeah, line ran 7 days a week but the people working on it had regular shifts. The example I remember people being frustrated by was not being able to pick up and drop off children at school because they were working then Monday-Thursday

Any idea how many (apprentice?) braziers Brompton were training up?

A stab in the dark would be 3/5 training, out of about 20 on the line brazing frame parts but I can't remember exactly.

The Bikegang photographs on the website you linked to show it being used with the Sturmey Archer SLS-30 shifter, which looks like it would provide indexing for the middle sprocket.

which looks like it would provide indexing for the middle sprocket.

it doesn't IRL.

Are indexed 3 speed shifters made for front derailleurs not an option?

e.g. the Shimano Acera left shifter: https://bike.shimano.com/en-EU/product/component/acera-m3000/SL-M3100-L.html

What is the point of going all weight-weenie on a Brompton? I know some aspects of the bike and accessories (mostly accessories) can be improved, but Bromptons aren't a bike where I care about making it marginally lighter.

Hear hear!

I have a M6R-X and I'll be adding a dynamo front wheel and lights once they arrive. Oh ya updated bars to get the S feel with a old M stem too!

Chose Ti as they don't corrode and that's all.
