Re: The timeless appeal of 7-speed gearing

Thanks for all the info! This made me check on the position with Marchisio cogs, and I learned that Marchisio is no longer making them apparently. So I just ordered a complete 8-speed set from Clemenzo in Germany (who claim to have them - hope they have all the right cog sizes) to keep in the cupboa...

Re: Bikehut/Halfords track pump

So ... can people comment on recently acquired pumps regarding ease of use (e.g. mounting and up mounting the head to/from teh valve) and amount of force required to pump? Must have a head which can be used on both Schraeder and Presta valves without fiddling about. Peter H I've had the bikehut pum...

Re: Bikehut/Halfords track pump

Skinny pumps are better for high pressure applications,fatter pumps will do a larger volume,but won't do a higher pressures. So the long thin ones are really for the track and time tea lists, who use skinny tyres and like pressure of150 psi plus. This is kind of what I assume, a slimmer barrel mean...

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...
