Give them a ring - however I would say the small (top tube circa 520mm?)

Blind I'd say small, but with a 27" inside leg you may need XS. Is a bike fit out of the question?

Is there nowhere close to you with a rig? I know Bike Science in Bristol has one.

it's very easy to sort out your size, measure yourself and then translate that to the nearest frame size for you .... 27 inches is equivalent to 68.5 cm. top tube measurement is there for your reach .... so arm measurements also required, etc.

I'd guess 's' but could be XS - have a look at the effective top tube length. I'm 5'9'' with a 31'' inside leg and I like my effective top tube length to be around 54cm; so I'd guess yours would be 52cm; maybe a bit less. However we are different shapes and sizes; it's more complex than that. I'd certainly phone them.

PS I got measured up for a bike by Ribble once, they were pretty good I thought. I do live in Preston though, so it was a no brainer.

I emailed them and they said i'd need a 49cm (S) frame.
Id love to be able to get them to do it, just it would be an expensive trip!

I'm a bit taller and get on well with a 52.

Have a look at this site for good sizing info

this site seems to provide a comprehensive list of measurements and some recommendations:

Don't forget compact frames are different to regular ones (typically the numbers are lower for the same sized frame). If in doubt go for effective top tube length & of course speak to the shop.

Hi All,

Im looking at getting a GF too but Iam stumpped at what size frame. I am 6ft 1 with a 33'' inside leg - they guys at Ribble are saying a 55 but this seems very small.

Is anyone else around my size who owns a GF or knows of someone? I am based in London so its a bit of a mission to check out the bikes at the whareehouse :-)

Thanks!
