- I think you're missing the point. If you have better bearings, go faster! The
- air resistance will quickly become the dominant force that you're working
- against. If you're skating with other people, then you may have a problem.
- Experts in aerobic exercise, like Covert Bailey, caution that such speed
- matching between people of different fitness levels (and, presumably,
- quality of equipment) is often counterproductive.
-
- One other thing: often, the problem with cheap bearings is their roughness,
- not necessarily the resistance. Rollerblade's Max Trainer bearings (the MNB
- 608RS guys) are very slow but very smooth. They feel pretty good...as long
- as people aren't passing you. Somehow, I feel a compunction to explain to them
- that I'm really not *that* slow on my skates. :-)
-
- A co-worker has a GMN 6206 RSR bearing on his desk. It reportedly comes from
- the transmission of a VW Beetle. After a long lifetime, it, too is very smooth
- but very slow (by in-line skating standards). It's the biggest bearing
- cartridge I've ever seen.
-
- Finally, I'm usually suspicious of people's early experiences on skates. Many
- beginners will have the "plain and simple experience" that brakes are
- impossible to use. They assume that such devices should take a minute or two
- of practice, then they'll be experts. What they don't realize is that one
- must, at least, have a fundamental grasp of the dynamics of fore-aft and
- side-to-side weight transfer before even beginning to master braking.
-
- The downhill ski industry has trained most people to take lessons when
- beginning. We need to do the same for in-line skating. Heaven forbid, it
- wouldn't hurt if the bike industry did the same.
