Hi,

I've the opportunity of buying a Trek EX8 '10 second hand. I've ridden a 19.5" and that was perfect. The one for sale is a bargain but it's 18.5" I haven't ridden one, but sat on one in store & the guy said that the 19.5" was a better fit than the 18.5".

How noticible is the size difference between the 2? I'm exactly 6', I currently ride a Rocky Mountain ETS X70 which is 18" but it's too small & I have the seat post too high & because it's got a high bottom brakcet it's not great throught the technical stuff.

I can't get the geometry for the Rocky Mountain so can't compare.

I would appreciate any knowledge you can provide me with regarding the sizing or let me know what you ride.

Thanks in advance.
I'm over 6' and have quite a large head.
