Re: Toolkit pliers?

As a general purpose tool I like the Knipex Pliers Wrench . The 150mm size is much heavier (170g) than some of the lightweight multi-tools, but it is a much more useful tool: ... If you are in Reading, Clas Ohlson sell 150mm Pliers Wrench for £30 https://www.clasohlson.com/uk/Knipex-Pliers-Wrench/p...

Re: Frameset transplant: Spa Titanium Touring

Did you consider attaching the front mudguard stays to the next eyelet up on the forks?
Both stays will be shorter so a bit stiffer.
Also if a stick or something catches under the mudguard it will tend to pull away from the tyre rather than towards.

Re: Dynamo Lighting - fit and forget?

I think the Cyo circuitry has been described as a voltage halver/current doubler. If a white LED needs say 3.5V at ~3Watts the input will rise to about 7V 0.5A which is converted to 3.5V 1A internally, so the LED in the front light is effectively the voltage limiter, since the current is limited by ...

Re: Replacement for HyRd disc brakes - suggestions?

Hi Brucey,

Thanks for the report.
Do you think the Juin Tech/Acor hybrid disc brakes are any better? Not many of these about I imagine so not much anecdotal evidence to go on.

where did you buy the fork from?


Custom build by Richard Hallett as the offset was a bit larger than anything off the peg. Went for SS partly for novelty.

Re: Lighting page updated (and CJ mentioned) but.....

The supernova site mentioned that the German bike lighting regs were updated this summer to allow high beam/dipped lights.
A description of these updates would be useful.

Re: Roller brake vs long drop dual caliper

Is this for a front or rear brake? The IM70 is one of the better examples compared to roller brakes further down the scale. The IM80 series are even bigger but not heard anyone say they are usefully improved. My limited experience is that roller brakes are OK but it can be tricky to modulate for str...

Re: SP Dyno Hubs Service Options from UK Distributor

That's why I like Sturmey Archer dynohubs, fairly easy to strip and service/repair if required + parts available (not that I've ever had to repair one......Yet). User friendly I believe it's called. I've renewed the bearings in a couple of them, though they were fairly abused over a 6yr period. :ro...

Re: Spa Dynamo & Wheel Bundle

Anyone have any experience of the newer & smaller SV-9 ?
I've not yet seen any bad reports, but reports of any nature are still elusive.
I sometimes toy with the idea of giving my Brompton a hub dynamo upgrade.

Re: DT Revolution spokes

No personal experience of 1.5mm mid section spokes but Gerd Schraner says in his wheel building book that after some bad experiences he won't use anything less than 2.0/1.8/2.0mm and brass nipples on the rear drive side. I guess the main issue is spoke wind up.
