Is it me or the tires ( or both)...
I did not get any riding done this winter until march. Over the winter I
gained 12 pounds.
In late feb I took the bike ( Spec Sequoia Comp) in for a tune up and
replaced the Specialized Pro (700x25)tires with Continental Grand Prix 4 Season (700x28)
I am running the new tires at 100psi.
The ride is much more comfortable than the Specialized tires, but after about
360 miles I cannot seem to produce the average cadence and speeds that I
recorded last year.
Most of the ugly hills I have to climb seem to require the bottom most gearing
on my triple (30x28).
Even going down hill feels a bit sluggish...There is one ultra steep downhill that
I had to hit the brakes intermittently to hold the speed down to 45 mph.
Now I just let it go and still only hit 45 mph.
Are 28s that much slower than 25s?
Should I be running a higher pressure ( the Specialized Pros I ran at 110 psi).
I am currently running at about 210 lbs and will be 72 this summer...
Perhaps my body is trying to tell me something.
This will be my second year of biking
