I presently have an early 90"s Cannondale Delta V 1000 HT:
front susp (80mm headshock), head tube 70 deg, seat tube 73.5 deg
I am looking at the new Cannondale full susp mountain bikes, specifically the RZ 120 and the RZ 140.
The 120 has a head tube of 69 deg, seat tube of 73.5 deg.
The 140 has a head tube of 68 deg, seat tube of 72 deg.
Trails range from some hardpack to mostly gravel to stony to rocky. I do a lot of climbing, of course what goes up must come down, but I do not barrel down hill like a want-to-be down hill racer.
With a lot of climbing, would the 69 deg be better than the 68 deg head tube angle?
Going from 70 to 69 is just a small increment, how would going from 70 to 68 be?
How would going from a 73.5 seat tube angle to a 72 deg affect the way I pedal?
Thanks in advance.
