I'm 6ft 1 " 32 " leg , I've tried an altitude and the 17.5 felt right and the whyte 19 steel and the medium felt best , cheers !

They're relatively slightly shorter in the top tube than stuff like On-ones, Cotics and that, so maybe a 19/20-ish?

Email Merlin, and they should send you a list of tube lengths, angles etc.

i'm 6'5" and have a 19" – it feels a touch small for me but might be bang on for you. My Merlin malt 2 in 21" felt brilliant.

I am the same size as you and I had a 19" C-T which I felt was far too short for me.

As ever, its all about length – the seat goes up & down! Get the eff top tube of a bike that fits you and start there.

can't find the top tube length for the 19 " any ideas

they are supposedly quite short in the TT compared to more 'modern' designs. Not that I've noticed significantly.

6ft / 32" Inleg / 19" here, and I love it.

Have you emailed Merlin?

I did when I wanted to buy one, and they sent me the info. I bought a 15"- perfect.

I've got the doc…I'll email to anybody if they want it but heres the geo for the larger sizes…

To give idea of how short they come up, my 16" Inbred 853 has an eTT that matches the 21" Rock Lobster!
