Re: What track pump

I'm only guessing but I don't think that the stroke v bore of a pump makes a huge difference to the effort required, although it obviously affects the amount of air pumped per stroke. I wonder if a cheaper pump might not have a valve ie be made like an ordinary bike pump? With a valve, which is sta...

Re: What track pump

Just saw this (oops) after posting a query in the Goods and Services section about track pumps. My main query is about how much force the different pumps need - my old SKS pump has had it and I got a replacement from the LBS which is much harder work. It will do for now (was not expensive and does t...

Re: Bikehut/Halfords track pump

I’d like to widen the discussion a little bit here. My venerable SKS track pump has reached the end of its life. Won’t pump at all (loss of seal) and I don’t think the pressure gauge has been working reliably for a little while. Multiple issues - I took it apart and don’t reckon it is worth trying t...

Re: Really Reflective Clothing / Bits

I have an Altura Nightvision jacket and a pair of the Proviz gloves.Shortly after I got them last winter, a friend told me she had seen this cyclist who was impressively reflective in her car headlights, then she realised it was me! The gloves are great for signalling as they stand out very well in ...

Re: Why are dynamo front lights so expensive?

Prices are extraordinary though and the bracket (oldwindbag's) broke to add insult to injury. Just not good enough at that money. The bracket was one of about 10 designs b+m do. It was to extend beyond canti brake straddle cable. It was separate to the light and was about £5. The light itself wasn'...

Re: Ride feel and drag on Greenguard; actual size on Marathon Supreme?

Oh dear, recently bought a 32-559 GG for the rear wheel on my recumbent after a) getting a glass p***re in the M-Racer and b) reading the GG has less rolling resistance than the M-Racer. My reading of the data in the tests linked to above is that the 32 mm probably has more rolling resistance than ...

Re: Ride feel and drag on Greenguard; actual size on Marathon Supreme?

Follow-up post in case anyone else has a similar question. I took the plunge and ordered a pair of Supremes in 37x622 (35c). They fit fine though they were really hard to get on and I had to adjust the mudguards as they are a couple of mm taller than the old 32x622 Greenguards. I went for a quick te...

Re: Ride feel and drag on Greenguard; actual size on Marathon Supreme?

IIRC the current generation of Marathons/Marathon pluses roll well (considering the puncture protection) but need to be inflated hard, at which point they become uncomfortable to ride on. That you consider them 'squidgy' suggests that you have been inflating them for comfort, at the expense of spee...

Ride feel and drag on Greenguard; actual size on Marathon Supreme?

I replaced the tyres on my 1980 Super Galaxy last year, putting on Marathon Greenguard 32x622 to replace the pre-greenguard Marathons that had worn out (7000 miles and 1 puncture - great). I've had the feeling that the new ones are more sluggish, and a bit squidgy to ride on, which I am not so keen ...

Re: Brooks saddles - a poll

One more vote for the Cambium C17 (see my post in the Cambium a week or so ago in the thread about Cambiums, asking if they should be comfortable from day 1). For me this proves you don't need the traditional leather option to make a good saddle, as the comfort level is close to what my old Flyer wa...

Re: Brooks Cambium saddle - should it be comfortable straight away?

Try the C15 carved, it's more forgiving I did have a look at the C17 carved but I thought it had quite a lot more "give" and therefore might sag. I'm happy with the standard C17. It does not feel nearly as hard to ride on as it does when you press it with a thumb! Each to their own. Lots ...

Re: Brooks Cambium saddle - should it be comfortable straight away?

I have a C17 on my touring bike - used for day rides. I bought it about a year ago and have ridden it 30-60 miles every weekend since. I am very happy with it. It was a replacement for a Flyer (B17 with springs) which had got saggy after about 7 years of similar use, and had started to need the tens...

Re: appraisal: 1987 super galaxy

Do measure up very carefully when considering the conversion to 700C. I found that the Weinmann centre-pull brakes on my 1979 (ish) Super Galaxy did not have enough adjustment. Luckily this came to light during discussion with the bike shop about possible extra braze-ons when I had the frame respray...
