Functional bikes. Not Porn not Anti

Are you sure?

The effective tt increases with each size.

edit!

I re-read your comment. Reach doesn't. Gotcha.

The top tube length is meaningless without the headtube, and seat tube angle, as well as bottom bracket drop, fork length, etc.

edit - you gotcha.

Cannondale recently revamped their SuperSix/CAAD12 sizing to be more consistent in different sizing.

Yeah, that's what I was getting at. ^

Miro, I have a cross check, with a spacer stack and a positive rise stem. I don't care. I love the bike so much. But it still annoys me that they do it. Why is the reach on the 52cm, that I ride, 389.7mm? That is so damn long for a 52.

54cm road bike ideally should have around 385mm reach (this is standard with a normal seat tube angle and 54cm top tube).

A race-fit 54cm road bike is around 395mm reach.

Really? My 58cm SuperSix Evo, "race fit", is 399mm reach.

the reach on the 54 is longer than the 56!? so confused

I would probably says a race-fit 54cm is closer to 390mm than 395mm, as every manufacturer have their own way of making a race fit, it's not easy to narrow it down to a specific sizing.

• Trek H1 fit (aka race fit), is 400mm, whether the H2 (normal fit) is 391mm.
  
• The Felt F-series is @miro_o's friendly at a whopping 412mm reach (with same height as a traditional 56cm bike)
  
• Focus Izalco is 405mm (but same height as a traditonal 58cm).
  
  

All this base on your size (58cm), Cannondale sizing is in-between race-fit and normal fit generally which I feel is a decent move as you only need to increase or degrease stem length by a centimetre to get the right fit.

the reach on the 54 is longer than the 56!? so confused.

Read all about it here, hopefully that should make it easier to understand.

Also confusing. And also found Cross-Check reach / HT wack. Dawes Galaxy fits much better for my functional bike.

The FBNPNA commuter gets refreshed with a stubby stem and 25's. BEHOLD THE FUNCTIONALITINESS!

Generally agreed on the surly geo chat. I love that my cross-check has a horizontal tt just for the looks but the spacer stack for a comfortable long distance position was ridiculous.
Revamping it now as a winter road bike and as such will be looking to drop the stack significantly. It should look a bit less silly!

I find the surly geometry to be fine. I have a modest spacer stack, a 90mm stem and a setback post, and my crosscheck fits great.

YMMV of course, but if we're getting into personal preference then I may as well chime in.

In terms of reach changing between sizes, or not, I'm not fully convinced that there's an issue with their approach. They produce a bunch of different frames. The trick is to select one that allows you to create your ideal position, no? So what if the 'sizes' don't increment in a given way - its more relevant to identify a body type/ fit preference that isn't catered for, then check if its actually common in the population.

I will concur that many surly builds look quite fugly, but meh, who cares (see thread title)

So what if the 'sizes' don't increment in a given way

This. People sizes don't increment in a certain way either.

I think surly geo is drawn with spacer stack and positive not as €uro stem which makes them work for 99% of the population.

If you H8 spacer stack get All city.

tarts allergic to spacers

@Mechamorgan

I have 35mm of spacers on my road bike an am totally at peace with it

It fit you because it fit you.

The only bike in the Surly line up that's actually quite decent is the Long Haul Trucker.

I see the numbers and it just doesn't add up, like paying £5 for a 500g peanut butter when a 250g one cost £1.50.

Functional should fit a wide range of people, not cause a line up to have near identical sizing with only the stand over height being the main difference.

The only bike in the Surly line up that's actually quite decent is the Long Haul Trucker.

Almost did that my next project because of the geo :) the 650b one that I discussed with you.

Did a bit of fawning over Mike's 853 Paconi with dynamo and frankendrivetrain (105 octalink triple with 10spd long cage veloce rear mech and 9spd veloce shifters) as he was replacing chain/cassette/jockey wheels in the workshop today.

thats making me all hot and bothered

What makes you say that about the lht?

Because the sizing is actually a little more consistent in the Long Haul/Disc Trucker.

Toe overlap on that Paconi looks lethal!
