Re: Internal hub geared bikes

Yes, "Road bike" usually means "Road Racing bike", and hub gears are much more commonly found on what are now called "Hybrid" bikes. These are increasingly being offered with the choice between drop bar and flat bar versions and it's wise to decide on the right version ...

Re: Has something changed in tyre valves?

The connectors on Lezyne mini-pumps are notorious for unscrewing presta valve cores upon removal, causing instant deflation of the tube after one has just expended significant time and energy on pumping it up. If you've recently bought such a pump and haven't yet used it, check that your removable v...

Re: Internal hub geared bikes

I'm not convinced that your Alfine with belt drive is any quieter than my Alfine with chain drive, Dobbo, despite your drivetrain being a lot more expensive than mine. Belt drive may have certain advantages (e.g. cleanliness, lower maintenance) over chain drive, but being significantly quieter isn't...

Re: Holdsworth Bottom Bracket

My Holdsworth is, I believe, from the 1970's or 1980's. It currently has fitted a TA Cyclotouriste Pro Vis 5 single chainwheel with matching TA cranks. I very much doubt that the TA cranks are original to your machine. Most Holdsworths of that era were fitted with SR (Sakae Ringyo) chainsets as sta...

Re: Is Evans' claim about e-bikes really true?

I think the claims are disingenuous. I ride a bike principally for exercise and the benefits to my fitness and health which result. For any given journey, a reduction of effort by means of electrical assistance would therefore be counter-productive. I could indeed ride a greater distance on an e-bik...

Re: Tyre and tube sizing mis match...

Patching tubes after every puncture is all very well but personally, I prefer to take a more proactive approach. I apply patches all over the entire outer surface of any new tube and, to ensure full coverage, overlap them like roof shingles. This approach not only fixes all potential punctures befor...

Re: Tyre and tube sizing mis match...

Why risk wasting £3 on a tube of the appropriate size when you can just use any old thing you happen to have lying around? Far too much importance is attached to tyres, when it's obvious that only a small part of their circumference is ever in contact with the road at any one time. That tiny patch ...

Re: Tyre and tube sizing mis match...

The question is begged, "If it doesn't matter, why do manufacturers bother to make tubes in different sizes?".
This is a rhetorical question, by the way, which means it isn't seeking answers.

Re: road surfaces after the winter

Well said, Flinders. All this austerity business is no joke when it comes to the roads - more and more cyclists are being seriously injured and even killed as a result, with no end to the situation in sight. Before spending billions of pounds on infrastructure for the future, they should fix the app...

Re: Should I stick with the Shimano Alfine 8 IGH or change?

I started out by trying to look at the marks on the cassette joint when the IGH is in 4th whereby I was going to shift into 4th from both directions. Now I'm going to look again at this when I have more time and when the light is better but I had a problem with checking this. Now when the bike was ...

Re: road surfaces after the winter

It's certainly the case where I am - I've lived here for 40 years and never seen the roads in such a bad state as they are at present. Judging from BBC news features, this situation is by no means untypical of the whole region nor indeed of the whole country. At this rate, all bikes will have to be ...

Re: Chain lube

White Spirit degreases and evaporates off afterwards if the excess is wiped off and then the chain left hung up for 20 minutes or so afterwards. To reduce the smell, I use Bartoline Premium Low Odour White Spirit (from B&Q) and shake the chain in a plastic screw-top food bottle. A quick blast w...
