Boardman Comp - Large or Extra Large?

jslater

Hi All,

I'm tempted by either the Boardman Comp or Team Carbon but I'm not sure which frame size to go for, and there's no Halfords that are local stocking either of them to try out. I'm 6' 1" and my inside leg's 87cm so any ideas of which size to get? Halford's website isn't exactly helpful on sizing!!

Cheers,

James.

If this is of any help

I bought a medium yesterday and I'm 5'11" with a 32.5" inside leg

Put your measurements into the fit calculator here:

then check out the proper specs on the beaordman website:

Geometry
Size Top Tube effective (cm) Seat Tube (cm) Head Tube (cm) Seat Angle (deg) Head Angle (deg)

Chainstay (cm)
Small 54 50 13.5 74 72.5 40.5
Medium 55.5 53 15 73.5 73 40.5
Large 57 55.5 17 73 73 40.5
x-Large 58.5 57.5 18.5 73 73 40.5

I'd guess you almost certainly fit a large quite well depending on you arm/torso length.

Like steve i'm 5'11" and seem to fit between a medium and large. In fact the fit suggests i'd be better on a large due to the larger top tube:

Seat Tube Range C-C
Your new bike's seat tube height should fall within this range. "Center-to-Center" signifies the length of the seat tube as measured from the center of the bottom bracket spindle to the midpoint of where the seat tube intersects the top tube. The seat tube height is most important as it relates to your head tube. If your seat tube is too short, your head tube will almost certainly be too short. This results in too low of a handlebar position placing an inordinate amount of stress on your neck and back. For this very reason, if you feel as though you could go with either of two sizes, going with the bigger frame is normally advisable. Please keep in mind that many frames come with a sloping or "compact" frame geometry in which the C-C seat tube measurement is artificially short. In the case of compact frames, you should primarily focus on the top tube measurement.

Thanks both, useful info - looks like I fall in between large and extra large so I think i still need to sit on one to find out for sure!
