Re: Brompton stem nutted bolt size (older style)

you mean the handlebar pinch bolt? A picture is worth a thousand words here. I assume we are talking about that bolt: https://up.picr.de/39301352df.jpg Any competent mechanic working on older bikes will have the correct spanners to fit these sizes. This may or may not be true for the UK but definit...

Re: Brompton stem nutted bolt size (older style)

Does the new allen key brompton handlebar stem bolt spare part pack come with fittings to make it backward compatible with older stems that took a keyed bolt and nut I wouldn'd expect so as those older stem types have been out of production for more than 20 years now. or or are those still availabl...

Re: Brompton with Serial Number "0"?

For cases like your’s (you want to date your bike, do have the frame number but are lacking the serial number, typically because the sticker has been removed or is faded) we created a collection of frame numbers with manufacturing dates in the German Bromptonauten-forum. As to my knowledge it is the...

Re: VW van cycle racks

Does anyone here use a VW van (mine is a T4 but I guess later one will be the same) with a tail gate mounted bike rack? I had a T4 with bike rack years ago. I had the one from the factory, massive, very well made and very expensive. I think the brand was "votex", though it was sold exclus...

Re: Where to get a Grocery Pannier in the UK?

I'm after a particular type of pannier, which commonly seems to be known as a grocery pannier in the US but I can't seem to find anything similar in the UK and was wondering if anyone knew of anything that was on sale here? https://banjobrothers.com/collections/panniers/products/grocery-pannier-fol...

Re: Hub Dynamo for winter commute.

It will be by far the brightest dynamo hub light ever created. I am always a little bit in doubt when someone claims to create some superlative something. The BUMM IQ-X is as far as I can judge the brightest dynamo light with StvZo-conformity currently available, still I do like the Edelux 2 more i...

Re: Hub Dynamo for winter commute.

It is, I think, not possible for shimano to supply their loose hubs 'in a well performing state' Slightly OT regarding dynamo hubs but interesting regarding Shimano hubs: Their Nexus Premium hubs typically are delivered undergreased as well but tightened way too much from what a friend who owns a r...

Re: Hub Dynamo for winter commute.

They were probably Shimano DH-F703 Capreo dynamo hubs. These hubs are cheap entry level hubs that are far from having the high quality bearings and build quality as the high end Shimano dynamo hubs like the Shimano 3N72. Jup. Still it was since 2010 until last year the default hub dynamo delivered ...

Re: Hub Dynamo for winter commute.

I IME shimano hub generators are supplied in such a state that the LH cone usually needs backing out about 1/4 turn in a built wheel. In a loose hub it is even more than that. Also the seals are quite draggy when new, because they are still tight and they often don't have enough (good) grease on th...

Re: Hub Dynamo for winter commute.

I see the Schmidt hubs as the best you can get, and the difference in cost isn't much if you expect to get a good few years of use out of it. That's how I assess cost. Cost per commuting year. (...) I would happily spend more on components that promise a long service life. Just looking at Spa's off...

Re: Hub Dynamo for winter commute.

Whatever set up you use the freedom from having to worry about charging batteries is well worth it. One tip though is always carry a head torch or similar in case of breakdowns. I was lucky the other day that a passing cyclist stopped and gave me enough light to fix a detached wire on my dynamo plu...

Re: Using a Brompton as a home exercise bike

Kurtkinetics offer a small wheels adaptor for their trainers that is compatible with Brompton wheels: https://www.kurtkinetic.com/small-wheel-adapters

Or - as Brucey said - use a roller like these https://www.elite-it.com/en/products/ho ... rs/rollers. Many model should fit.
