V Brake failure

Friend of mine brought her bike round because the "cable had snapped". In fact as you can see what has happened is that the bracket that the noodle sits in had bent rendering the brake suddenly useless. For such a safety critical part the design seems to rely on a tiny tab of metal. I know...

Re: Raleigh Randonneur- touring?

Thread resurrection alert :) True shimmy is a rather rare and somewhat mysterious phenomenon that some people like to debate about until the cows come home. If you are getting some sort of vibration or wobble or whatever regularly, there is a problem that should be investigated. There is nothing inh...

Re: Rims for Audax Bike with Dynamo Hub

My poshest bike has H PLUS SON Archetype rims and my more often used one Exal LX17. In a blind test, on the same bike with the same tyres, I doubt I'd be able to tell which. I also have this combination and agree with the above. If you are planning on using the Archetype rims then I would recommend...

Re: Vitus 979

I have an Alan Super Record. Similar bike but tubes are screwed and glued and I think the Super Record had thicker tubes to make it stiffer. My frame is 52cm and also rides beautifully. 02-IMG_8190.JPG I have been slightly put off riding it by the stories of fork failure. I do not suppose there is a...

You poor thing. I hope you are feeling better now. From your story and the photograph my money would be on this being a Photocontact Dermatitis caused by coming in to contact with a plant then being exposed to sunlight. https://dermnetnz.org/topics/photocontact-dermatitis/ If so I would expect only ...

Re: Inner tube concerns

Jobst Brandt said; A tube can be folded into as small a package as when it was new and practically airless, by sucking the air out while using the finger opposite the stem to prevent re-inflation. This is not done by inhaling but by puckering the cheeks. Although the powders inside tubes are not poi...

Re: New wheel build, spoke seating question

Thanks, I tried to measure the flange thickness but with the spokes still in situ I could not get my calipers on straight. FWIW the hub is much smoother than the Nexus dynamo hub that was in the Decathlon wheel it replaced. I see that you can now get clones of the DT Swiss spoke tension meter on eBa...

Re: New wheel build, spoke seating question

I am a novice wheelbuilder and this is the only spoke tension meter I have used. You just place it on the spoke and release the spring tension to take a reading. IMG_20200420_210146882.jpg Seems to give the same reading each time. However to translate that in to spoke tension relies on this spring a...

Re: Castelli sizing ?

[Could you let me know the circumference of your hand, all the way round where you've got the tape. That's the measurement that the company uses.]

22cm measured like this

Re: New wheel build, spoke seating question

Thanks Brucey. Had a feeling you would say that ☹️. Pity as it is the best wheel in terms of trueness and even tension that I have built so far (although that is not saying much).

Sorry made a typo on the hub, it is a DH-3N72

New wheel build, spoke seating question

So what with the enforced lockdown I finally got round to building up my Shimano DH-3N73 dynamo wheel. Using Sapim race spokes in an Exal LX17 rim. 2 questions. Spoke tension is 100kgf using my lifeline tension meter (cheap version of the parktools one). Is this Ok? Should I have used washers to sup...

Re: Stupid question about bar tape wrapping

Just for fun I wrapped these bars in what I think is called a harlequin pattern.

Black tape goes one way, blue tape the other so depending on your point of view always in the right (wrong) direction.

Road sign "cyclists dismount"

Hi I came across this sign on Avenue Road, North of Regents Park London. IMG_20190722_140420025_HDR.jpg There was some building work going on in one of the houses that obstructed the pavement so pedestrians had been diverted on to the cycle path. What is the legal status of this? Surely I would be e...
