Re: RX-RD5; another flawed Sturmey Archer 5s hub? -surely not....

Everything I read about hub gears on this forum puts me right off them. Even worse that Sturmey managed to engineer a reliable 3-speed hub then totally dropped the ball with anything else, and repeated the same mistakes. For the UK climate a good reliable hub gear would be ideal on a utility or com...

Re: SunTour 'New Winner' freewheel; state of the art in 1978

I well remember Regina freewheels. The difficulty of stripping them down to swap sprockets drove me nuts - but I did persevere so that I could swap cogs to suit different purposes. I never did buy a Suntour freewheel, instead replacing Reginas with Maillard (subsequently to become Sachs Aris) which ...

Re: SA front drum brake conversion

In order to do this the 'starlock' washers would need to be removed. It looks like these would have to be replaced with new after removal (i.e removal would probably damage them). Anyone have any idea if they sell these items separately? You might be lucky and be able to re-use them, but they are r...

Re: Swarf from rim

+1 for BBB Techstop/Tristop. They now do Ultrastop as well.

Good performance, economically priced. I now use nothing else.

Re: Entry Level v More advanced bike

Over the years I have done a number of rides over known courses on bikes including basic 531 framed bikes, typical of those common in the 60s - 90s, a modern high end aluminium framed road bike, and a Surly LHT. Only on the Surly am I consistently slower - by about 1mph over 20 - 50 miles. Any perfo...

Re: Sturmey Archer front hub brake: 70/90mm

I find 70mm drums fine with 700 wheels. I rode Lon Las Cymru, hilly by any UK standards, carrying (lightweight) camping gear on a drum braked bike without any problems.

Re: Repairing inner tube punctures

........ I also like to repair at the roadside, unless there's a reason not to (Rain, train to catch...) it's not a big task and that's it, job done, rather than doing half a job and leaving something else to do later. +1. I take the view that I have to find the location of the puncture in order to...

Re: Spa Cycles - Canvasman saddlebag

I use an SQR uplift but with a modified bag frame. I welded on a "bagman-like" frame that supports the bottom of the bag. It prevents swaying as well as sag.

It wouldn't be difficult to make a bolt-on version if you don't have access to a welder. I can provide photos if interested.

Re: 32 hole rim onto 36 hole hub - "alphabetti spoketti"

an omission in this thread is a recipe for building 36h rim onto a 40h hub. TBH it is so much easier to build a 32h rim onto a 40h hub I would suggest that you do that instead. .......... cheers I did one of these quite a few years ago - I still have it in fact. I had just acquired an old Sturmey A...

Re: Cold weather and safety on the roads

It depends on your commute. Mine is a minimum of 10 miles each way, mainly on ungritted rural lanes and is prone to large patches of sheet ice in some conditions. In the past I would have risked it on "normal" tyres, or driven, but since winter tyres have become readily available and I hav...

Re: Fixie: Why?

. .......... IMHO it is highly unlikely that anyone will ever produce a variable fixed gear hub that will satisfy every fixed gear user. The reason is that they might be super-sensitive to any backlash in the drive; many such riders don't even tolerate small amounts of chain slack, or sprockets in ...

Re: Cantilever brakes

Those are wide profile cantis which are relatively insensitive to straddle height, but all the previous stuff about pad type and cable condition etc is still important. Plus there have been at least two different cable pulls on Shimano STI levers - you will get more power with the type with the leas...
