Cool, all good advice, thanks all. Had a quick blast round the block and bars felt interestingly different, would like to see how I feel after a few miles on them, optimistic on that front. As for the seat, I think it's basically horizontal now, but will check tomorrow. Fore/aft adjustments to follow after that. Thanks again. Is that right? Remember small tweaks make a difference - I noticed a 2mm difference in seat height last week, when I regreased the seat tube and re-fitted it slightly differently. What this shows me is you've gone from an emphasis on forward canted seat position, straight past neutral without collecting Β£200 from the community chest, to rear canted in one leap; it might not appear much without pics to compare but it's a pretty big change when you view the above, I realise you will rotate your torso on the saddle and it's not necessarily an alteration to your body angles (of the same degree) but IMO that's quite a big change you've just done there with the saddle. It could put your hips back and induce lower back pain and not allow a smooth back curve; but it might not of course, just need to be aware of what you're doing here.

Cheers Rad, thanks for highlighting. As I say I need to look tomorrow, my quick run round the block was in flip flops so hard science not to the fore just yet!

I'm 5'10'' and the geometries / angles are different but I think we can see that your hand is likely twisted back a bit more than mine. My hands sit in the curve of the hoods and the bars quite naturally and are a bit like a tennis grip with a v pointing back up my forearms, I set it this way a fair few months back now after having hand troubles. I twisted it forwards twice on consecutive rides to get to this position as at first it didn't feel intuitively right but when you settle to it, it works well. I wonder about pushing the hoods / levers down around the bar a little more still yet, whilst leaving the bars in the same angle but haven't done this, as the position is quite comfy at the mo' and gives good support, so I'm not messing with it. What size frame is that on your T3, Rad? Just curious as we are almost the same height

54 -'Compact' not 'French' fit (Google bike fit styles) ! Decathlon chart would put me on a size up, but I know from MTB days that I err down rather than up. I spent an age doing bike sizing before mail order, including one on-line which took about an hour to work through various measurements. My bars are forward of the front spindle due to what I think are oversized stems for their sizing / geometry but it pans out fine for me. I have toyed with a more touring style shorter stem but never felt too stretched so stuck with original. Probably means I'm set more forward and perhaps more 'race' than is sensible for a born again cyclist, hence all my hand, arm and sometimes back ache issues, resulting in a real need to focus on bar position and general fit. But in hind sight, now I've worked on it all, got fitter and Rule #5'd it through the initial half year, it's turned out ok. Suppose it's the old balancing act between comfort and performance thing in a working example!? Also demonstrates the fluid nature of bike fit issues perhaps?

Yes, I find after years I still alter my position through the season to suit my fitness and the type of rides I'm doing

Ok, my OH helped with measuring the pedal/seat bit so should be all good, good video demo, thanks Rad. Saddle horizontal according to spirit level. Missed the hood with my right hand on a short run (sans flip flops) this morning so need to get used to them where they are now, but it feels good.

There was an article on BC website last year saying there are two different types of rider, the constant fiddlers like me and those who just ride. Apparently one of the pro's rode half a stage on the wrong bike until he was told and swapped

I'm fidgety in all other aspects of life, don't see why cycling should be any different!

Some interesting stuff in this thread. I've been getting numb hands after about 15km, so will have a look over the weekend. One thing that strikes me, is that the bikefit website says you should do most of your cycling with your hands on the brake hoods. I tend to grip more like this, which is perhaps half of the reason for my numbness: ( edit, obviously I'm not actually Bradley Wiggins, but his hand position in this photo is pretty much the same as I usually have)

I get hand numbness all the time on the bike but have just learned to live with it. I suspect it maybe due to a partially trapped nerve in my neck as I sometimes get it when I am lying down. My main reason for replying was to thank you for posting this picture. One of my favourite moments in pro cycling. Brad in yellow leading out Cav to win on the Champs Elysee - perfect end to the 2012 Tour.
