I just changed my crank to Dura Ace 53/39 and combined it with my old KCNC cassette 12/27, from my old bike (with compact crank)...what's your opinion on mixing these two cogs ??
I will use this bike for my trainings now, but I'll also race with it... I'm not pretty good rider and was always riding with compact cranks, so I'm wondering If maybe someone could explain how harder my shifts are going to be ( in % please ? ) ?
I'm also considering to go to 23/11 on the cassette, does anyone have experience with that ?? - probably hard on hills, but I think I could manage it someday, since my new bike is 6.6 kg
I would appreciate any comments regarding these questions, and thanks for your help !!!
On the results compare the speeds with the range of speeds you normally ride (I ride my long stretches with 30 - 40km/h).
But since that was my first ride and the whole geometry of the bike is not the same as before, I think that things may come better soon enough. My riding position is not fitted correctly (need to fix seat position + unappropriate handlebar), so I am hoping that eventually my speed would increase
Ofcourse I have to do some serious climbing to see how hard actually it will be, but according from today's experience I might even survive the suffering !!
Thanks for the gear computers, really cool stuff !!
P.S.: I ride around 4.000 k every year, but I did also short/middle distance triathlons in recent years (not good results, believe me ), my average cadence is approx. 80-90, and on the 45k flats (only 300m elevation) my best average speed so far was 34 km/h - longer distances usually 30, depends on elevations !!!
I typically cruise at 19-21 mph depending on conditions and at a 105 cadence it I have a ton of gears right in my sweet spot.
if u are just cruising i say keep the 12-27.
As for changing my cassettes - I have also a 11/23 T at my home, but for now I won't change it, It's too hard for me at the moment, maybe I'll change in future years, I'll see about that
