Re: Oldest Still Serving Panniers/Saddle Bag

I have a Carradice nelson Longflap that came with my first "grown up" bike - a BSA Gold Crest - around 1970. Like the bike, it looked decidedly secondhand even then! It has a North Street badge so that dates it to the 1960s: http://www.classiclightweights.co.uk/components/carradice-compone...

Re: DT Swiss R460 - Build and Fit

Good question, so have just been and checked. Answer: Dead easy, no tyre levers required. My rim tape doesn't go right up and over the raised section of the rim - the bit that is meant to retain tubeless tyres - so that probably helps to make it easy to push the tyre into the well. Nevertheless, I a...

DT Swiss R460 - Build and Fit

I was looking for some widish but not too heavy rims and these seemed to fit the bill, but they are tubeless ready which, I understand, often results in a very tight tyre fit. Well, I can report that my Continental GP4000 II went on without any fuss using fingers only. Rim tape was Velox cloth 16mm....

Re: ORIGINAL COLOUR FOR A HUMBER FRAME/BIKE

I don't know if it needs coachlines. I restored a Raleigh of similar vintage that had red coachlines, but I cant find a good enough colour photo. Has anyone got a good colour photo so I can copy any coachlines (or lug lines?) Thank you. Not a colour photo but I have a pdf of the 1952 Humber catalog...

Re: Cycling to work in hot (or bad) weather

I always leave at least one complete change of clothes at work. My commute is currently a minimum of ten miles each way (well it will be when we resume after lockdown) so I normally ride in cycle specific clothing and get washed and changed on arrival. There are no special facilities, I just change ...

Re: Token Square Taper (ISO) Bottom Bracket

.......... There is a fundamental problem with having two lip seals 'in series' if you like which is that unless the inner one leaks lube out to some extent, the outer one cannot always have a film of lubricant at the lip, without which the lip will soon wear and become ineffective. Worse yet it ma...

Re: Token Square Taper (ISO) Bottom Bracket

I take your point about replacing the outer seal on the bearing. The one I would really like to replace is the one at the outer edge of the cup that looks like a thin rubber washer on a metal stiffener. So far I haven't found any for sale. Given the high price of the bearings compared to a more comm...

Token Square Taper (ISO) Bottom Bracket

Other than Campag originals, these are about the only viable option for users of Campagnolo chainsets requiring 102mm axles i.e. Chorus / Record. I have a few of these chainsets and have been using them for many years, including on commuting bikes. I found the original BBs had a pretty short life in...

Oh, I don't know .... there a quite a few ex-TTers on here - some more recently ex than others. (I have now just about got to the position where I think I have probably retired rather than "am taking a bit of a break").

Re: How much faster is a TT bike than a relaxed road bike geometry?

For me the difference over 10 miles on a flattish course was about one minute. At the time, on that course, I was able to do about 22.45ish on the TT bike and about 23.45ish on a road bike. This all depends on your riding position. While I was able to ride with a near horizontal back on both bikes, ...

Re: Seat angles

Additional trouble that I've got is that I love Carradice bags but don't like Brooks saddles so use SQR so there is a limit to layback. The SQR frame bends quite easily, so you can get at least a couple of centimetres further layback than with the standard arrangement. It is best done in a vice but...

Re: Single speed / fixed gear ratio?

My three speed work bike has direct drive at about 67" (47x19 on 700x32 tyres). I rode fixed for many years on gears in the mid to high 60s and occasionally the low 70s. This was on a light bike with tubs so a bit easier to ride quickly than my current bike - also slightly smaller wheel diamete...

yes the T, TF is a very handy looking hub ....... ....... However not everyone wants a 25% reduction in low gear. I think it makes sense but not everyone agrees.

Re: Fixie: Why? Why not?

When I first started cycling it was common practice to ride a fixie through the winter, one theory being it taught you to pedal smoothly. Add to that the 1/8" transmission is longer lasting than 3/32", having to pedal all the time keeps you warmer, you have more control when it's slippery...

Re: Best SPD pedals

I also experience a bit of "foot squirm". It is a bit more noticeable with worn Look cleats than with tighter fitting (i.e. less worn) SPD cleats. I only notice it at all if I look down when pedalling - I assume it happens all the time though. However, I never had any problems when using c...
