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.

Re: Why the Rohloff Speedhub is (secretly) inferior

the 'simple indisputable fact' ignores the fact that having ridden x-thousand miles on a derailleur transmission, you are left with little more than a heap of valueless scrap metal. If you do the same thing with a Rohloff, you are left with a Rohloff hub, which is worth something (quite a substanti...

Re: Organisations (mis-)using your data . . . [ er, probably ]

As for the rest of your post utterly ludicrous. Indeed, now we know his opinions are based on some crackpot extreme political beliefs rather than anything to do with hubs or cycling, it's easily ignored. Is that really the case? I’d agree that nationalism and racism are too often the sources of muc...

Re: Why the Rohloff Speedhub is (secretly) inferior

I am also convinced by the Rohloff hub and run several of them, dating from early 2000s until relatively recent, each w/o any issues. It is no doubt expensive but on the other hand I do not see any alternative that would deliver the same value in terms of gear range, low maintenance, usability and b...

So, if I can overcome this slight irritation and accept this- I am wondering what front dynamo lights you good folks would suggest? As far as I am aware, the pashley front dynamo only pushes out around 2.4w- I'm afraid that my understanding of dynamos and ratings is basically zilch- with this very ...
