Raod Bike Advice based on SPECS

James5000

Hi,

I have a dilemma, tried two bikes at the bike shop, both have similar specs and they were both black - the bike shop guy who was new, put me on a girls bike and then a guys bike, the girls bike (I am a dude) was actually more comfortable and felt better. when he realized his mistake, he said the geometry was not good for a guy - does any one know if it matters?

I have the specs below: first bike is girl, second men - I am 5'6 - thanks:

Top Tube Length 525mm 530.0mm

Reach 369mm 376.0mm
Head Tube Length 150mm 135.0mm

Don't know the models, one was a Giant, was one a name I never heard of but, had Shimano 105 groupset.

He actually printed out the specs for me.

Thanks

Are you still growing?

Components for both were pretty much the same, alloy, shimano 105 groupset, decent tires.

No, done growing, way done -

I noticed that most of the geometry was exact except for these few and some very little:

Seat Tube Length 460mm 490.0mm - 30mm
Stand Over Height 757mm 755.0mm - 2mm
Top Tube Length 525mm 530.0mm - 5mm
Stack 562mm 539.0mm - 23mm - this seems substantial
Reach 369mm 376.0mm - 7 mm
Head Tube Length 150mm 135.0mm - 15mm
Head Angle 72° 72.3° - .3mm

Does stack matter that much when it's MM or headtube?

Thanks
