Re: Knee Pain

You are more likely to get injured with too high a saddle than too low. (stretching for the bottom pedal) Set your saddle low enough so that you can pedal smoothly "through the bottom" at high cadence on your worst day, when you are tired and your legs are stiff. Good point about setting ...

Re: Knee Pain

That's great, thanks Colin, much appreciated. Apologies, I should have used bigger labels. I've dropped the seat down 30mm, and will try that. Top of my list now is injury prevention and rehabilitation. I don't really know the natural angle of my foot, I've never paid that any attention. Maybe I dip...

Re: Knee Pain

The previous photo is at 26.5mm lower (where my heel just touches the pedal). These ones are at 10mm, 20mm, 30mm, 40mm lower (labelled on the top tube). I have tried to keep to a normal cadence on the turbo (although using a turbo is a bit new for me.) Thanks.

Re: Knee Pain

I'd do that fitting with the heel on the pedal at full extension as usual, and then flex slightly because of the previous inflammation and set the height from that. Done. I've dropped the seat so my heel touches the pedal. It feels low, but looks better. This is a photo of my heel deliberately drop...

Re: Knee Pain

Thanks for the feedback. I'm a bit reluctant to change anything just yet, because it was set up by someone who knows a lot more about seat height and bike setup than I do. I also think the primary cause is me overdoing it. So I need to be more aware of aches & pains. And yes, the physio is a goo...

Re: Knee Pain

Knee feels better after a (3 week) lay off. Now to check other things. This is the setup I have, from a professional bike-fit. Today I had a short ride, then put the bike on a turbo and captured this still from a video. Looks a bit high to me. And looks quite a bit higher than the photos in the guid...

Re: Yet another reason to avoid carbon frames

The details and photos for the Holdsworth Mystique says it is fitted with low-rider rack mounts. But talking to Planet X they advise against the use of fork mounted pannier. Probably sensible, but a shame. I need a rear rack, and a front option might be a nice extra. Carbon fibre (and glass fibre) i...

Re: Yet another reason to avoid carbon frames

As a materials scientist, I know a fair amount about the virtues of different materials. CF (in its various forms) can indeed be a wonderful material. However in the real world, there are problems. Problems so bad that they kill people. Other problems are that the sort of CF that infests the cycle ...

Well spotted, thanks. Looks like GRX will take 42mm tyres with the double chainset.

Re: Expert advice on choice of front derailleur, please.

Thanks for the replies. I spotted that Campagnolo quote maximum tyre size for a front derailleur as 32mm. And Shimano say their GRX gives wider tyre clearance, but doesn't quote a limit. That got me thinking, and measuring. https://www.campagnolo.com/UK/en/Components/chorus_front_derailleur https://...

Re: Expert advice on choice of front derailleur, please.

Does anyone know where I can find the maximum tyre size for a (road) front derailleur? I cannot find that in the Shimano documents.

Re: 6 month suspended sentance for death by dangerous driving

I wouldnt argue for jail time but I'd like to see him off the road for at least 10yrs There is a lot to be said for that. Proving dangerous driving, beyond reasonable doubt, to a jury with a fair number of car drivers, is very hard to do. Convincing a jury or judge to send an otherwise "good&q...

Re: Knee Pain

Thanks foxyrider, fair point. I should worry less about the bike set up, and listen more to my body. The warning signs were all there, and I deliberately chose to ignore them. Now to heal and start again. Slowly.

Re: Knee Pain

Thanks Gearoidmuar, I checked that thread - very informative. Looks like flats are a good idea for a few weeks, once I can get back on a bike again. At the moment I'm struggling to stand or walk, never mind ride. 2 weeks ago my knees ached a bit after a 100km ride, so I took a few days rest. Last Sa...
