Re: Bob Jackson World Tour Tyres?

Much as I dislike weak wheels caused by over lightening I also dislike overweight tyres. Kevlar beads,which make your spare foldable,are the way to go,and if you are riding on tarmac you don't need tread,or much tread. Marathon sports in 30 width are good,as are gatorskin,32s. If you get punctures o...

Re: WHICH WHEELS

The only things to worry about when you choose touring wheels,and this is a CTC forum,are durability,durability,and durability. In practise,as Spa will tell you a pair of Exall LX17s properly built on LX 36 spoke hubs are as butch as you need to go. I do have lighter wheels,mostly built by me for fu...

Re: Painting frames - some thoughts......

No metal has an indefinite fatigue life! But if metals are kept well within their elastic yield zones at all times then fatigue can be ignored unless the designer,/fabricated produced a bike with stress raisers. If you kW what to look for there are many out there,but fillet brazing or welding reduce...

Re: I need a new pair of fine nosed pliers

I was going to say that there is nothing wrong with my drapers. And there certainly wasn't,until I cruelly abused them. Sometimes you just have to get the job done and if that means wrecking something,then its a shame. But they are all still out there and useful,albeit ground to different profiles f...

Re: Salvage and Refurbishment of Lepper Leather Saddle

Neatsfoot oil can oversoften a saddle so don't actually soak the thing in it by inverting it and plastering the underside! If its cracked it will stay that way. Try just bulling it up with boot polish like a squaddies boots,but wear black shorts! Or brown,of course,but neatsfoot oil will darken it b...

Re: Frame back from framebuilders with wrong rear spacing

It is the amount of dish in the wheel that matters. He who taught me the rudiments of wheel building over half a century ago just could not really accept dishing,although,like me,he had to accept it. A dishless seven speed wheel should be possible,but such hardware as is available is ether expensive...

Re: The Disc Brake Naughty Corner Thread

The only simple safety procedure that reohn2 could be referring to is abstaining from using the front brake whilst going downhill!

Re: The Disc Brake Naughty Corner Thread

In spite of the warnings from the late Jobst Brandt front discs are still fitted to the wrong side of the fork. This means they will eject the front wheel from the dropouts in certain conditions. Lawyers lips and tight sqewers do not stop this. This s really quite scandalous,you can source the proof...

Re: Frame back from framebuilders with wrong rear spacing

As the tubing is apparently Cod settable and the cracked chain stay was replaced I can see no reason at all why you should not reset them. The amount of bending is very minor and steel is not exactly aluminium in its level of fatigue tolerance. You do need what are known as egg cups,these are used t...

Re: Colt saddle

One of my brooks saddle covers has spent in excess of 60 nights in the open on tour without leaking. Can I repeat that it is width that is the most critical factor in saddle comfort? Too wide is as bad as too narrow,but there is a largish window. It depends also on your sex,how wide yer ischial prot...

Re: Mercian 1970's rear brake reach possible issue

Having made sure that the mechanical bits of the brakes,including pivot bearings,are as good as they should be (which may mean better than new..........) then go and buy a pair of every sort of premium brake block you can and keep changing them over on the front until you find the best for the rims ...
