I plan to purchase a set of rollers.
One of many questions I have is which size rollers do I get? Either the 3" or 4.5" Kreitlers.
How do I determine this?
Looking at some of my riding log entries, I seem to average high 16mph (16.8mph) averages on solo rides of 1-3 hours.
I'm looking to ride a minimum of 1 hour on the rollers when I can't get outside.
Maybe up to 2 hours...
In any case, which size rollers will give me the right amount of resistance without killing me and without having to purchase the killer headwind unit, assuming it's not the way to go (cost-noise) and something I'm not going to outgrow, assuming that's even possible?
Or, do I want the easiest to use (4.5") and get the killer headwind unit later if it turns out to be too easy or I get better and faster?
I'm 42, not a racer, just completed my first century last month, in reasonable shape and would hope to ride for the next 15 years. I also mountain bike.
I've searched almost every thread for the answer. Either I missed it or it's not there.
If you have personal experience with the 3" and/or 4.5" rollers, and/or the killer headwind unit...help me out please.
