Bike fit / correct riding position

Not sure if they do testicular descent

I have hippy for that it would appear

So I currently ride a Tarmac in a size 58 (100mm stem), awaiting the delivery of a Cipollini Bond in size 56. Is it likely i will be able to make it fit me with a longer stem? The headtube is pretty tiny. Geos here

hippy's definitely trying to steal Scherrit's business. :)

or try this...

Chakra alignment is key to on-bike symmetry.
Are they for two or three bolt cleats?

I've done some ģroup training sessions with Paul Mill from Elite. He's a good guy. No experience with bike fitting or anything else, though.

Has anyone used East Central Cycles? Much cheaper than others

I'd be interested to know how they are...

Does anyone know of a good cheap cleat fitter in london?

Considering a new commuter frame, all-city nature boy disc appeals, in particular because of its drop-outs hopefully solving my main frustration with my pompetamine.

The 55cm has 386.5mm Reach, 583.9mm Stack
The 58cm has 392.8mm Reach, 609.6mm Stack

I ride with ~ 488mm Reach, 660mm Stack (to handlebars)

Just wanted to check with the hive mind that the 58cm is the frame I should be going for, could I get away with the 55cm (how to work out stem/spacer combo)? Checking because 55cm's seem to come up on the bay etc. but rarely 58cm. Anything else to consider?

you sir need a spreadsheet

Was attempting to use bikecad, but after installing IE and java on my work computer I was informed it is not sufficiently secure, hence turning to the hive mind.

A spreadsheet it may have to be, what is a ~standard stack for a stem, 40mm?

dont include stem stack in the calculation just frame and headset stack plus frame, stem and bar reach.

Why not (stem stack)? I thought you would use at least half of it?

Quick google spreadsheet (if I've done it right, do I need to factor in headtube angle, was hoping not for quick and dirty calculation?) suggests 55 will require 55mm of spacers with a 100mm 12 degree stem. Flat handlebar so calculation not complicated by bar reach.

Reach Stack Stem Length Angle Stem Stack Spacers HBar Reach HBar Stack
386.5 583.9 100 12 0 55 484.3147499 659.691217
392.8 609.6 100 12 0 30 490.6147499 660.391217

Whereas the 58 will only require 30mm and have also have only 20cm rather than 23cm of exposed seatpost

I've been blindly using this spreadsheet for all my bike indulgences over the last few years. Comes out perfect every time.

Thanks, that's a great spreadsheet, which it turns out, on trying to save, that I already had saved!
It does use 1/2 the stem stack + headset + spacers and it transpires the head tube angle makes quite a difference.

Confirms the 55cm would need at least 130mm -10/12 stem and ~8cm spacer stack (somewhat ridiculous) whereas the 58 would work nicely with a 120mm -10 stem and minimal spacer stack, time to unwatch the 55cm that is on the bay!

Long arms and legs, with a short torso, seems to necessitate for 'pro' length stems.

Yep. In reality, pretty much all stems are 40mm high, +-4mm, so when it comes to replicating between bikes it's not really a variable that makes much difference.

I'm long legs, short torso short arms, a true dino, which means I end up needing large frame size to get the stack I need, and then a relatively short stem (100mm) to get the reach right.

I need another bike fit, my knee is causing me issues and i'm pretty sure its fit related. Apart from the Bike Whisperer (I need to see someone quickly due to long rides coming up soon) can anyone recommend anyone?

The person I used previously is not in London now so ideally a recomendation would be good, has anyone used Cadence in Crystal Palace or Elliot @ Super Domestique?

@hazzelfrazzel I believe has

Is there any literature from a bike fitter discussing what one should do with varying crank lengths between bikes and maintaining as close as possible a fit between them as possible? I've always thought saddle height should be adjusted by the difference in crank length, to maintain same leg extension, but I've never been sure. Is angle at the top of the stroke more important?

Depends on the bike of corks.

My TT bike has shorter cranks to open hip angle because I have crushed my leg blood tubes or something. If I adjusted the TT bike as per my road cranks, plus the difference, I wouldn't get so much hip angle opening. So you can adjust a little bit but if you're just trying to replicate between two bikes of roughly the same purpose I'd try and get them equalised.

Yes I have! Considered super domestique, but they didn't have availability.

Following a recommendation from a friend I went with Simon at cadence. I would also recommend him, and I've been back to him multiple times with 2 other bikes since my first fit.

I was mainly interested in super domestique for the custom orthotics, so it's worth saying that Simon at cadence also does these, but for an extra cost!

Thanks!

This was basically my thinking between the two, for orthotics it works out slightly cheaper with Super Domestique but only marginally. Good to have a recommendation for one of the three fitters at Cadence, thanks!

Don't know much about bike fitting per say. But an educated guess would leg length would be the main deciding factor.
