Brompton owners

Why has the rear has 3 bearing may I ask?

Also, is I’ve got a Brompton bag but I don’t have the block. Any point of upgrading to a H&H version or just keep to the OEM plastic version from Brompton.

OEM plastic is legit the best, not aesthetically but functionally.

Rear hub, 2 bearings in shell, 1 in the driver

Thanks and one assume the front from sjs is 6800 bearing

Plus is there a difference with red and blue bearing of 6800?

6800 is the bearing size; the rest of the code is the spec.

Riding in this morning, going over a rough section, I heard a sort of ping from the back end and now the derailleur doesn't shift. The cable seems to be intact and the derailleur moves. What's likely to have happened there? I am hoping perhaps the cable securing bolt was just a little loose?

Lost the circlip holding the cogs on?

Pic?

An interesting possibility - would the bike remain rideable after that? I rode mine the rest of the way into work OK, it's stuck on the smaller cog. If I try to shift to the larger cog it doesn't shift and is a bit noisy, as if it is trying to shift on.

I have just had a look. The circlip seems to be there, no idea what the ping was. Everything seems intact. I think the issue is that the derailleur is / was being impeded by crap. I can't believe how bogging the bike is around the derailleur area.

Send me a video or some photos @thebromptonman on Instagram

Thanks @sbbohr, as above I think some serious cleaning up is needed. I can now get it to shift but it is a bit noisy on the large cog.

Edited to add: having now had a closer look, I think this was just down to grit on the spline or tube that the derailleur slides on. There does seem to be a massive amount of grit around from our council’s ongoing experiments in shitty road repair methods. It’s quite sticky grit, due to the treacle or whatever cheapo tar subsitute they use. In retrospect I think the ping I heard was more of a crunch-ping, as I mashed one of these bits of anthracite with my cogs.

Folks, taking some steps back from life so going to turn off the forum for a bit.

I will be just focusing on my instagram / facebook for bike and brompton stuff so do follow along there; @hobbscycles / @thebromptonman

Thanks all for your business, not sure if its just a holiday or longer!

G'luck.

All the best to you @sbbohr

Just musing about a dynamo set-up. Does an Edelux II work with Brompton bags, i.e. is there enough clearance above the light?

yep, just needs one or two brackets; fits over the front brake and under the FCB.

Repost from dodgy ebay listings thread:

Pretty dodgily brief Brompton CHPT3 listing on ebay at the mo, got some interest but seller has no history and description ridiculously brief and lightweight considering what it is - anyone missing one?!

https://www.ebay.co.uk/itm/374469476788

Looks like they've lifted the photo from a website as well!

Ah, didn't clock that! Blatantly dodgy clearly!

Chpt3, Brompton, fans.
Chpt3 mailshot (Fri) said the following:

the first 500 customers that pre-order a pair of Transit shoes will
gain early access to the Brompton x CHPT3 V4 bike in February 2023

So effectively looks like you are purchasing an option to get access to the purchase list (and a pair of shoes)
The only issue is the price of the option is not yet known and whether the shoes look any good.

I'm guessing for shoes priced at £250, so estimated 8% of Chpt3Brompto price.

If you really want a Chpt3Brompto, and have the funds, this might be a way to get there. I think a good way to drum up interest in their other product, but I asked Chpt3 directly and their response was so vanilla it is of no value.

Is the CHPT3 just a normal Brompton with a red bit, fat tyres, a straight bar and no mudguards, or am I missing something?

This one also has a blue bit!
But yes, pretty much what you said. It's just a P-line.

Does the new V4 CHPT3 have SA hub still, or have they gone with a derailleur?

Literally the same as the P-line.

Do you have a link?
Can't seem to find anything online.
