There is another thing that i forgot to mention. The only thing that maybe i dont like 100% in my bike, is how it's handling on downhill. On tight turns sometimes i feel like im putting more effort then i want to follow to the tight turn. Like the handing is too slow.So i was also wondering if i go narrow handlebar if this feeling will become more lively, and better reactivity then i have now
Most of the time you'll hear that narrower handlebars are more sensitive/less stable. Yet for me a narrower bar feels more stable and makes it easier to hold a line, while going wider feels more sensitive to inputs and can feel less secure at speed. Talking just about how steering feels, I find that going narrower with the bar feels somewhat similar to going longer with the stem, or having more trail. However, my experience seems to go against the common wisdom, so it would again be best if you could test multiple sizes to be able to tell for yourself.
But handlebar width and stem length are just details in the larger picture, and they cannot really change the main handling characteristics of the frame - and Colnagos with their relatively long front centers and lots of trail tend to steer somewhat slower than average.
Thanks Fiery for ur post. I measured the handlebars i was using in past 3-4 years. on Pinarello FP3 Most Jaguar XR Alloy is 42.5 cm in hoods, and 42 cm in drops. Zipp Service Course SL-80 im using now (last year), on Colnago C60 is 42cm in hoods, 44 in drops.
So decided to experiment and to go with a bit narrower version. So i just oredred Easton EC90SLX3 in 42 cm size, which mean 40.5 cm in hoods, and 42 cm in drops.
And yes, the only thing i dont like about C60 is slow steering (or im still used of Pinarello FP3 steering, i had before). Will see how this will change (if change at all), with narrower handlebar.
Thanks a lot for everyone.
