the smalls are suitable for 5'0" to 5'8", the meds for 5'6" to 6'0" and the large for 5'10" to 6'4". i use to have an m6 which handled like a dream, but the 951 is lighter and more adjustable for all types of course

 I'm about 5'9" so would I want the small or medium? What would the advantages be comparatively? Also so you have a med, how tall are you? Would you rather have a small? have you ridden other bikes, how does the 951 compare? Sorry for all the questions, but big big thanks if you get around to answering them! I need to find more info on this bike before I get one. Any where I should look? Didn't see too much discussion in the forums about them. Thanks again

 No worries about the questions i am happy to help. i am 5'11", i could have had a med or large, but the med was better for me length wise. for you i would suggest the med as the small is only recomended up to 5'8". my last 3 bikes have been intense, each different obviusly but not how you mean in terms of things like giants etc, the m6 and 951 just seem to be on rails, they handle mind bogglingly well, but the 951 is a bit more agile, and has the added adjustment the m6 didnt have

 thanks a lot man

 your more than welcome

 Hey, you would need a large at 6ft1, size medium is 5ft6 to 6ft0, large is for 5ft10 up to 6ft4, hope this helps, regards tim

 so your fucked if your 6,5 lol

 longer seatpost comes to mind

 or they have a canny few adjustments on the frame

 place the g3 dropouts in hole 3, which places the bottom bracket height at its highest point, therefore highering the bike

 love the bike, and love the double barrel, if i ever change frame i will be making sure the double barrel fits so i can keep it

 buying bikes isnt luck

 your demo is still very nice tho
