Their Sutton shop is on Sutton High Street and has been for the last 157 years.


My mistake.

I've spoken to a few other fitters and I'm getting disallusioned with it all. Also read a few threads on tri/tt bike fitting and wonder if it's as well understood and mature in the industry as road bike fitting.

I'm getting tempted to do it myself again, has anyone used bike fit software themselves? I'm looking at Bike Fast Fit as a starter. If one is able to get the angles correct this way, is there anything else key that is missed? I'm think the rocking of the hips when pedalling, for example.

It's well understood by good fitters which is why I use Retul....john Dennis is not only a good fitter, he is a physio too...

I am all in favour of self education, but this is more than just plugging in some angles

Try lowering your saddle a tad.

Tbh, a lot of experience and the Mk.1 eyeball go a long way in bike fit, like 90% of the way. Do you have a picture of your latest position/bike?

We still seem to be on a different page, I wasn't asking how to correct hip movement, I was asking what might be tricky to measure at home and giving this as an example.

I don't have a picture from the assessment last week, unfortunately.

As you mentioned ST, I looked at the "bike for Ramsay" and the survey reckons that a pad stack/reach of around 600/485 would be common for a man my height.

Taking ST as a reasonable source and so eaking to Argon18 it seems the size S, as suspected, would be right for me as it has a range of pad stack 576-676 and pad reach 433-499.

I just don't know if I should trust ST and survey information based on height to select a frame...

Everyone's different, so wise to be cautious. I know I have a good position, because a) it looks 'about right' b) I seem to get a lot of bang for my watts and c) Andy at Bike Science thought I was very close to the Retül recommendation anyway. And YET, Slowtwitch has me as quite an outlier on some of their charts.

Back to you. Where did that Reach of 318 come from then? That's the unusual figure.

If you want some rough angles, this is an easy tool to use.

NB: I don't necessarily agree with the "fitting" recommendations that it provides when you've fit it to your position.

I managed to get a session (last) weds for he follow up on my roadie and we ended up using it to get a rough pad stack/reach using my road bike and a variety of seat post, saddles and bar positions.

S. I could've gone XS, there wasn't much in it.

Will enjoy putting this together. Can't decide on Athena or Ultegra, just waiting on a response from a supplier on mixing carbon and alloy Athena components and probably go Athena.

Just don't look at my crappy friction shifters and cheapo brake levers.

I moved to SRAM mechs a few years ago, so I could use the gucci R2C shifters.

So it's arrived and passed the most important test. Smile

Just waiting for the other components to arrive - going with Athena 165mm crankset and derailleurs.

We've all had an 986.... please tell me it's an 'S' Smile Mine went long before we had kids.

Will it fit in there with cranks and everything else hanging off it?

But "upload picture" function isn't working...
