Re: Gear changing on 6 speed Brompton

Ref. Bruceys answer: lockwasher part HMW526 is not symmetric, and if it is misplaced (eg inverted) the derailleur will sit at a strange angle and may indeed not shift correctly. My problem wasn't that this anti-rotation washer was inverted. I'm not sure what it was, something to do with the gearchan...

Re: Warmest Winter Gloves

I find that Ozzo gloves by Inmotion products are ok for all but the coldest weather. They come in yellow or red, with pail grey leather palms which are ideal for indications being seen. They are also available in black.the colours do show up dirt, though. If really cold, I go for golfing mitts from ...

Re: Time to replace rim?

I found an old vernier caliper in my toolbox and ground away part of the measuring surface so it has almost 'ball' measuring faces that get in behind any lip. I have checked all my rims and set 1mm as my limit. One set of MTB rims are down to 1.1mm and weinmann concaves down to 1.2mm. I found a dump...

Re: Gear changing on 6 speed Brompton

I had something similar on mine after taking the wheel out. I can't recall exactly what it was, but it was something to do with the plastic part that goes between the frame and 'hollow' nut. It might have been a spacer misplaced or something and the plastic housing wasn't sitting correctly. It was o...

Re: Dynamo wiring - advice on more durable wiring around frame

Low power, as in 'not one of the ultra bright LED lights that dazzle other cyclists, but one adequate for purpose.

Re: Dynamo wiring - advice on more durable wiring around frame

I run a low power basic LED light on my wife's bike as a standlight and just in case the dynamo wire, etc., fails without her noticing. A fail-safe. Strictly speaking, it is also bad electrical practice to run an electrical current through a rolling element bearing (e.g. headset) although the erosio...

Re: Frame identification.

Ok. Could be One of several. Sort of predates the now popular sloping top tube.
I will see if I can see a frame number but, as I have recorded all our other frame numbers, it is either well-hidden or full of paint.
Thanks.

Frame identification.

Can anyone help in identifying this frame from the upstand on the head tube? We have owned it for 10 to 15 years. We took it to Argos racing cycles for checking for truth, they thought it would be a renown maker but didn't know who. It has vertical rear drop-outs, so can't be that old? There are no ...

Re: Pedalling out of the saddle with a Sturmey Archer AW hub

Never had a post NIG hub. I have had 5 or 6 'AW's' and maintained several others for friends. I have never been shy of standing on the pedals up a steep hill. Never had a problem with false neutrals, in fact, I have only ever had one fail. On a tandem, the cruciform distorted and engaged two gears a...

Re: Dynamo wiring - advice on more durable wiring around frame

In my experience, the usual failure mode was either corroded terminals or wire fatigue. The former is best avoided with plenty of grease. The second is to loop the wire round several turns as a coiled spring so bending occurs over quite a length, not just at one point. This is mainly at the headset ...

Re: Stealing by finding

I have found two good bikes dumped. Both were probably stolen and hidden for later retrieval. I contacted the police, the first I took to a station. They said that if unclaimed within 7 weeks, I could collect it. The second I told them the details but kept it at home for 7 weeks. I recently found an...

Wow, and I thought I had to be the only person weird enough to try and remove that huge gap in the otherwise useful 'megarange' ratios !!

Re: Creaking saddle rails

One last possibility:

I have Rolls saddles on about 56 bikes (commonality for the Andrew Haig QR saddlebag clip!).

On two, one of the rails snapped just aft of the seat pin clamp. Obviously long-term fatigue.
Check for cracks....

Re: Which mudguards

If it has mudguard clearance, I suggest Crud roadracer 2 or 3. These are fairly long and do a good job on two of my bikes. The roadracer 3 velcro on to the inside of the rear seat stays and the front forks BUT: I would peel off and throw away ordinary velcro. Use 3M Dual Lock strip (ebay). It is a m...
