Re: Spa Zircal wear

That's not good. One of my Mtb's has a Stronglight 30t zicral and has had no less than 5000k in offroad, with mud in spades, and is ok. The drivetrain has had two chains and the same PG990 cassette so far. On a road bike I'd expect no less than 15000km from a 40-42t middle ring, provided it's not th...

Re: pedal washers

That was grime+dried grease, you can see the pedal axle thread is actually fine and does only show surface rust. I don't think the gaps in the roots/crests of the thread are enough to cause problems because of moisture or dirt expanding; it is also my opinion that most of those cracks are likely due...

Re: New Route Planner

Are the files in the correct format? Garmins do not accept .Gpx files. Also, have you transferred the file(s) in the correct folder of the Garmin when connected to the PC?

CinQ "the plug" intermittent working

I inherited a mk2 that was rated as "not working well", so rather than putting it in the bin I've quickly made an encasing for testing it without having to wire it inside the forks. A length of carbon forks steerer has done the job. The original wire at its end has now two female mini-spad...

Re: pedal washers

... those are very thin cranks? a problem waiting to happen? there is almost no metal around where the pedal goes? a very poor design? all that prettiness just wasted? They were never designed to last a lifetime. Lightweight stuff, where the lowest possible weight is a priority. If you have to repl...

Re: Road/MTB compatibility

The XT rear mech with SS cage was popular in the early 90's, but it's worth to note that the maximum rear sprocket used was a 28t, also it was forbidden to "cross" the chain. May people have to abandon a race because of this :lol: Btw, the discipline of trials is almost inevitably done on ...

Re: pedal washers

those cranks are an object lesson in 'how not to design a crank for the UK winter'. They are (IIRC) machined out of a billet of an ostensibly high strength aluminium alloy. Firstly, they are nowhere near as good as a forged crank in the same material. Second, the minimal design unavoidably means hi...

Re: Servicing MKS Sylvan Touring pedals

If one is planning to use the pedals for long, and is taking them apart, it may be a good idea to drill a 2.5mm hole and tap it to M3 for a grub screw that can be removed for the use of a grease gun. Under the pedal is probably the best option.

Re: bike longevity

I have always been surprised how much upkeep is required for most bicycles. Where I live I see many, many bicycles of every sort used -and neglected- for transport. There are many old-school racing bikes, often equipped with lovely equipment from the 70s and 80s, which clearly never see so much as ...

Re: Road/MTB compatibility

I have had a similar setup, but I have arranged it so that the chain is long enough to use big-big, and I advise anyone to always set up their transmission likewise. It is just asking for (big) trouble if the chain is not long enough for this.... cheers That is not a good idea especially with Shima...

Re: Shimano PD-M324 how to tighten the lock nut?

IIRC (I may not) PD-M525 was still an expensive pedal (to make) at the time, not a budget pedal. I don't think the cartridge system was particularly inexpensive to implement to start with, because it relies upon some super-precise machining; the tolerance of the fit between the pedal body bore and ...

Re: Head bearing rust

... I'm not sure what you mean about "grease-ports that are so far away form where the bearings actually are". The Record headset has 4 holes at 90 degree intervals in the bottom cup. What I mean is what you have seen: the holes in the Record headset are only a few mm away from where the ...

Re: Mould on Carradice cotton duck panniers

You may wash it with vinegar first, then to give it a good wash in the machine with other stuff (maybe wrap it in another canvas bag) but remove the wooden dowel.
After it's fully dry, you need to wax it again, the wax is easy to obtain and best applied now that is warm 8)
