I’m not aware of any fitters in my city that also handle this sort of thing. I wish they did as I use orthotics in my normal shoes and they’re no good in my cycling shoes. I’ve had to experiment with clear wedges myself

That does make a lot of sense because ski boot fitters can work wonders. I've always thought a bike fitting is most useful for foot and knee related issues. Clearly the more an outlier you are the more you'd benefit. Although I do wonder how well trained in this area the average fitter might be according to tarmackev's post. Possibly a consultation with a podiatrist with an interest in sport or cycling and then a trip to an experienced fitter would be a better. Not something I have clue about, but it's something I'd be keen to look into if I was at the start of a competitve cycling career.

Has anyone used the Retul Muve system to size themselves up for a new bike? Did it do a good job of determing what size bike you needed?

I don’t think the Retul jig is as good as the one Trek Precison Fit uses... the one that basically looks like two columns on rails. They have the same functionality, so it’s just down to how much of a PITA it is for the fitter to make adjustments.

None of those in my city, apparently!

Some Retul fitters use that jig anyway. It's all about the fitter, really, not the hardware...the software can help with the assessment, but it comes down to how the fitter interprets the data.

Nope......

Okay, then take a look at this article?

Perhaps any calculator resource is not as good as asking the seller.
I have always done this.

I'd not ask the "seller" either. Mostly all they have access to is those sizing charts.

That blog only goes part way to proper sizing, but it's better than a look up table.

Im getting there guys slowly and thank-you for the replies...

After trying a few bike fit calculators online and getting different answers to the same question, curiosity was replaced with distrust.
I can't afford a bike fit so that's out. Feedback I have reviewed often reveals conflicting feedback. Couple this with a bike I don;t have yet...

As one responder mentioned earlier on in this thread. I do have my current bike and existing riding position. (This has taken me a year or so of tweaking to get just about right) Put together the existing geometry for the bike and I can quite accurately work stuff out. Just spending some time videoing myself riding in various positions also assisted in getting an understanding of the different riding positions I employ whilst riding. Initially confusing it ended up being very useful in understanding the whole "fit" question.

Add in scale 3:1 technical drawings that I spent some time making up of the existing bike and the proposed bikes and I think I am making progress.

It also pointed out one of the online calculators that seemed to churn out good data.

The one MAJOR drawback...if i get it all wrong I can;t blame anyone else other than myself!

:(

Thanks for the feedback folks.

Gutsy.
