Well for me it has. I had not ridden in 15 years when I got my racing bike in a trade. It had an 11 25 cluster and at 265# and even now at 212 some of my little steep hills were a challenge. I could not spin up them and standing was not really better. So I got an 11-28 cluster and my average on the same route got a little better.
Now here comes my bent. It is not as low geared as same and it has a 11-28 on back. Those same hills were only a tiny bit easier then on my road bike and I am spinning pretty slow. So when I upgrade to 9 speeds I got a 11 34. well my average went up a bit because now I can spin up the hills only the worst get me down to 60 or 70 rpms verses 40 to 50 and more work that less gearing got me
Ha anyone else noticed this?
