Re: cycle computers, generally

Second time round the clock on my nearly 10 year old Halfords cheapie; round the clock.jpg The only fault so far is that at around 12000 miles or so the first digit 'disappeared' so it reverted 'back' to 2000 miles. Anyhow, over 20,000 miles and still alive so not bad for a tenner or so!! No need t...

Re: Kool Stop vs. Swissstop?

Swissstop make pads and blocks of different compounds as do Koolstop. However most comments refer to the manufacturer and not specific compound. Swissstop have unfortunately stopped making the green V brake inserts, which I have found provide good braking, little rim wear and are generally squeal fr...

Re: Angle of drop handlebars - how to set?

As the bar end only just touches the top tube it sounds like a very minor bar adjustment angle would solve the problem. You may not even notice the difference at the hoods. Some drop brake levers have spacers to set the lever nearer the bars, but in my limited experience drop bar levers seem to be l...

Re: NCN5 Blockage due to Roadworks

PS Official guidance is provided in Traffic Advisory Leaflet 15/1999 which makes it rather dated. At the time, I did have an exchange of views with the author which concluded with him telling me that it was aimed a "professionals" rather than cyclists. https://webarchive.nationalarchives....

Re: Trucks Do Not Have Cyclist-Obscuring Blind Spots

Cardiff city centre is mostly pedestrianised. Streets closed to traffic (other than emergency vehicles) and numerous arcades and malls. It is such an attractive place to walk round that people drive there especially for the pleasure of having a walk around the shops. https://www.google.com/maps/@51...

Re: Road bike tyres - how long / far before replacement ?

what are the conditions where tyres wear most? running at low pressures? climbing? accelerating? braking? rough roads? cornering? I would say rear tyres wear most when climbing accelerating and braking. I don't use "road", ie narrow, tyres but I think this would apply whatever the type of...

Re: Downhill then immediately up : gear selection ?

I sometimes stand to climb a short hump in a higher gear. If nothing else a change of position is good.

Re: Trucks Do Not Have Cyclist-Obscuring Blind Spots

The real issue is that cyclists and lorries (motor vehicles) should not be using or trying to use the same piece of road (highway) space. People will make mistakes, but these mistakes should not lead to injury. Don't agree, I'm comfortable with HGVs for the most part, I have far fewer issues than w...

Re: Where is all that gravel?

If you want gravel (stone chippings to be accurate) there's loads of it here in South Wales. But I'm not sure I'd take anything less tough than a full-on mountain bike on proper gravel. Rough bits commonly have chippings of 4 cm or bigger, with the odd rock sticking out. And you can venture off ont...

Re: Twist grip gear changer on front deraileur

As above. When you change down you slacken the cable which is obviously quite easy to do. When you change up you tighten and pull the cable against a spring and the chain, which is obviously much harder.

Re: Trucks Do Not Have Cyclist-Obscuring Blind Spots

It's largely a legacy of our history that we share the same space. Unless we rip up our built environment and start from scratch we are going to be sharing space with motor vehicles. In my nearest town all the streets I regularly cycle on are required for vehicular use, and I want to use them too. ...

Re: Absoulute Black- non round chain rings

https://www.sheldonbrown.com/biopace.html seems Biopace hurt riders knees Having read that page it would appear that Sheldon liked Biopace because they were easier on his knees and assisted his pedalling performance. He comments that it was other non-round chainrings - with the alignment 90 degrees...

Re: Absoulute Black- non round chain rings

I got the impression Biopace were 90 degrees out of correct orientation, the smaller diameter should have been oriented at the TDC/BDC crank position to help rotation past the 'dead spots' and then the larger diameter (effectively higher gear) should have corresponded to the power position when the...
