Re: Helmet manufacturer confirms helmets are not designed for incidents involving motorvehicles

Hi The wearing rate went up to close to 100% from about a third...snip "Of cyclist injuries recorded between 2010 and 2013: 78 per cent were recorded as wearing a helmet; 5 per cent not wearing a helmet and 17 per cent were unknown (Victoria Police data)." https://www.tac.vic.gov.au/about-...

Re: Helmet manufacturer confirms helmets are not designed for incidents involving motorvehicles

Hi Hi Reductions like these should be unmistakable And then there's the statistic that is frequently used that cyclist numbers declined dramatically Regards tim-b That is why the rate is calculated. The figures are taken from traffic surveys. If the sample size is reduced the standard error increase...

Re: Helmet manufacturer confirms helmets are not designed for incidents involving motorvehicles

Hi Hi Reductions like these should be unmistakable One assumption is that all riders in Oz and NZ wear the helmets, and those that do fit and wear them correctly. It's a bit like saying that drivers in the UK don't use hand-held mobile phones when driving Regards tim-b The wearing rate went up to cl...

Re: Conti GP5000 actual width

Hi The utility cyclist wrote (not me) :) The Conti 4S are the only tyres that I've had come up small on those rims, why would the 14mm reduce the tyre cross section, where does that information/statement come from? ETRTO specify internal rim width, tyre pressure and a 24 hour wait between fitting an...

Re: Carbon vs Aluminium at the £1500 mark

Hi Do you really need disc brakes? Unless you're regularly going out in wet, gritty conditions or hammering down lots of steep descents then they aren't necessary on UK road bikes. Mountain bikes and adventure/gravel bikes are a different story by virtue of being off-roaders If you can see beyond di...

Re: Carbon Fork - corrosion issue with dropout

Hi
I'd suggest that once corrosion has set in that fork's days are numbered. Google galvanic corrosion and get your friend to contact the dealer/Trek as there might be a lifetime warranty to be had. And don't ride it!

Re: Helmet manufacturer confirms helmets are useless in incidents involving motorvehicles

Re: Conti GP5000 actual width

Hi You'll need to do the maths but the 14mm rim reduces the tyre cross-section circumference from where it should be for nominal width tolerance testing. Consequently some actual width will be "lost" as well as some height but the amount of each will depend on ply construction and pressure...

Re: Torque wrench 6-30nm

Hi Where do I hang the bag of sugar? What I mean is, if torque is angular force at a distance from the pivot (there, I told you I don't understand) does it matter where I hang the bag of sugar? Or more to the point, where my hand is when I'm actually tightening a bolt. There's a "bag of sugar&q...
