Re: Strange sound

My old Gal had a wheel that did this. It was an Elesa Endeavour rim, double-walled with those spoke well cups that rivet the two walls together. If they are made with cheap plated steel they can corrode leading to noise. On my wheel they had rusted. A squirt of PTFE spray applied sparingly* around the top of each cup joint and excess wiped away - this soon cured it.

* too much spray lube and it risks migrating to the inner tube then...............bang!
There's always dry PTFE lube as well.

Re: Mudguard heating - deforming to fit

Looking at your photo, I'd suggest cutting the guard in half at the crown would be the best way to gain the necessary clearance. Fortunately, as you have used a long rear with front of crown stays, this will aid the rigidity of this fix significantly. How you choose to re-attach the front section of the guard to the crown is up to you, but a stainless rear bridge mount would be the obvious choice. You should have one kicking around as I'm guessing you'll have bought two sets of guards to make your hybrid setup.

Alternatively, do you still have the old front guard? The crown angle bracket off that could either be re-deployed, or you could possibly use the section of this original front guard, between the crown bracket and the nearest stay bracket, as your new leading section. Re-using the section of front guard would also mean no need to re-attach the crown bracket.

Re: Car lamps : one-eyed monster and other outrages

I can't stand the latest LED lights when the user flashes their lights. It's like a high powered photo flash going off and somehow it's more sudden than a halogen bulb being flashed. The other driver may be flashing to me as a 'thankyou' as they pass. I wish they wouldn't. Don't they see the same effect when another driver with the same lights flashes them? Perhaps it's because so many of these drivers are in high up SUV's that they don't receive the full blast that us normal road users experience.

BTW, I'm speaking as a driver. I guess that as a cyclist I don't even warrant acknowledgement of even being there on the road!

Re: Intermittent issue onto small chainring

Sweep, this maybe what you need https://www.ebay.co.uk/itm/SHIMANO-FD-R ... :rk:7:pf:0

ImageAlthough it's designed for a 12T difference, middle to big ring IIRC and a 50T big ring, it's pretty close to your set up. In it's favour it's a 9 speed cage and made for a road chainline. Bonus - it's all silver 8)

You just have to be a bit more careful where you lock it up, in that the radius is too small to fit round the biggest posts - and it rules out locking the rear wheel. But I usually manage to find somewhere suitable.

+1. I also use Pitlock security skewers on the wheels for added reassurance.

Re: Intermittent issue onto small chainring

Has the eccentric shim for the FD been mentioned yet? Assuming that the XT mech is a 34.9 tube fitting and your frame tubing is 28.6mm, the shim below will work well in moving the mech inwards further - achieving that reliable shifting you are after. It also has the benefit of being able to move the FD for and aft a bit, which can be useful.

In fact emergency vehicles are exempt from RVLR.


Well that's alright then :lol:

But seriously, the idea that individual police officers feel compelled to modify something as important as flashing blues, with something as Heath Robinson as black tights...
Shouldn't they be discussing this apparent problem of discreet blue lights, collectively, at a higher level and requesting a solution through the Home Office?

The Police are doing questionable mods to their flashing blues!

If you're ever pulled over by the Police, now you too can check that they've not been doing their own illegal light modifications to their vehicle...

Tights! Now that is inventive. But of course, foolish, highly irresponsible and probably illegal. :roll:

Re: Every breath we take: the lifelong impact of air pollution

I don't think that atmospheric Co2 had been viewed as directly toxic to human health before, has it?
https://www.theguardian.com/commentisfr ... nvironment

A Co2 atmospheric concentration of 1000ppm will be reached by 2100, on current trends. This concentration of Co2 has an effect of reducing cognitive brain function by 21%! Such concentrations are already found in urban environments right now, most tragically in inner city schools. Also, bedrooms have recorded C02 levels of 2000ppm. Which might be one reason to explain why many people feel so groggy first thing in the morning.

Just when we collectively need to understand and act on pollution and climate change, it turns out that our ability to clearly think these things through is being retarded by these pollutants :(
So that explains Trump then :twisted:

Re: Interesting Seatpost Layback/Suspension Adaptor On Ebay

Rjb, please excuse my lack of imagination, but how would you execute that crank layback adaptor with regard to the saddle wires?

fastpedaller wrote:It looks like it's aluminium for the adjusting block, and a steel alloy for the spring wire. It could work for a while, and then cause a nasty accident? Any metallurgists lurking here?
You may well be right FP. Thinking on redesigning the 'spring', could a good metal workshop create a simple single loop coil (similar to those deployed on Brooks saddles) to reduce the stress on the bendy bit? Sorry, not sure of the correct terminology! ...oh yes, it's called a spring, doh!

Interesting Seatpost Layback/Suspension Adaptor On Ebay

By complete chance I've just come across this interesting seatpost layback adaptor. It's actually marketed as a suspension device, but it looks like the layback property would be of interest to many on here. https://www.ebay.co.uk/itm/292557535769 ... noapp=true
s-l1600.jpg

I've no idea whether this design is widely available (this one is from China), or to a different specification. It concerns me that the spring wire material is aluminium. So it may not be as durable as steel wire. But it does seem that the design could have merit and yet I wonder what drawbacks there may be? Perhaps imply too much stress on the spring? I imagine this can't be the first time the design has been made and sold and yet I don't recall seeing anything like it before. It's striking to me for it's simplicity and even a certain elegance, compared to one or two of the designs I've seen mentioned here previously.

Who is up for making one in their workshop? :P Would titanium wire be any good?

Re: Slipping seatpost

I should also mention my own epoxy putty fix that I used a while back on an oversized seat tube. Well, I put a skim of it on the seat post, then sanded it back till the post fitted the seat tube. It may have been a bodge, but it worked.

Re: Slipping seatpost

Someone up thread mentioned carbon anti slip compound. I'm interested to know why this possible fix (for a few £) wouldn't be a quick solution. Is it because it wouldn't have the water proofing properties of grease, or just appear incompatible with it? Grease does seem a bit counter-intuitive an application here, with it's lubricating properties. What's really needed is something which is both a friction compound and one which reduces corrosion and water ingress. Perhaps mix the two together.
