Here is the current setup with stem down to the headset cap.

If I was to go lower then it bigger neg stem/flat headset cap is needed.

Drop to handlebars is 70cm.
Don't think my dodgy shoulder can take more in its current state.

I would get toe overlap in any frame around this size.. Not sure if that's avoidable unless you go larger.

sychen, your setup looks great :thumbup:
Sorry I shouldn't have stated the obvious, toe overlap is unavoidable in small sizes, and us shorties just have to live with it.

Currently I have a tarmac SL5 size 54 and after a bike fit (the one of specialized) I changed the stem from 100mm to 80mm.

I am 1.75 with center of BB to saddle top currently 72.7cm

The truth is that I do not like my bike with such a short stem.....

Although I used to ride 54 size specialized bikes with 100mm stems after a surgery on my lower back (from a crash) I started feeling too stretched.

My question is:

If I move to Sl6 (which has slightly different geometry compared to sl5 ) in order to keep a stem of minimum 100mm which size do I have to choose? 54 again or 52??

Thank you!!

Without looking at charts/specs and therefore not giving you the answers per se, look at Reach figures. You need the Reach to be 10mm shorter to use a 10mm longer stem.

the 52 Sl6 has a 38cm reach vs 38.7 of SL5 54size

The top tube (horizontal) is 53.1 for 52 SL6 vs 54.8 of SL5 54

Sychen - are you in Sydney? Looks like a Sydney ferry wharf and Gladesville Bridge in the background. Maybe Chiswick wharf at a guess?

I have a 52cm, but should have bought a 54 (I'm 5' 10"). Let me know if you're interested in buying my SL6 Disc!

5'10 Frame size 54
Saddle to BB - 73.5
Stem Length -10 120mm
Handle Bar has a 80mm reach 130 drop
Saddle to bar drop 10 cm (with the shortest conical spacer provided with the frame)

I have minor toe overlap because my cleats are setup more on the back.
