Punishing rollers for masochistic cyclists.
The 2.25-inch diameter alloy drums of the Kreitler Alloy 2.25 Rollers provide the greatest resistance of any Kreitler Roller unit, simply because they have the smallest diameter. In fact, these 2.25-inch rollers have approximately 90 percent more resistance than the largest 4.5-inch rollers, meaning you'll test your mettle when riding outdoors simply isn't possible, due to inclement weather or frigid winter conditions.
Like the Alloy 3.0 Rollers, these are built to roll in an ultra-smooth and quiet fashion with their ABEC 5 bearings and alloy end caps. They're compatible with Kreitler's Killer Headwind Fan and Flywheel (both sold separately), unlike the cheaper Challenger Rollers. Since they have alloy end caps, you'll find they're heavier, subsequently carrying greater momentum than cheaper offerings made of polycarbonate.

Best damn rollers ever
- Familiarity: I've put it through the wringer
I’ve been riding Kreitler rollers since the mid-1990’s. My first pair lasted 23 years (l did have to replace a rear drum when the bearing wore out, but that was after 20 years). Bought my second pair from CC last winter. Still great quality and the best design. Note: buy the 2.25” rollers because they offer the most resistance. I once had a different brand of rollers in the 1980s that were 3” or 4” diameter drums that did not offer enough resistance once you built up your fitness.
Kreitler is the best. I recently bought a different brand of rollers that I could collapse into three pieces so they fit better in the car. I tried them last night and I’m returning them today because the distance on center between the two rear drums is too short. Kreitler’s distance between drums is approximately 11 inches; this pair I’m returning is just over 10 inches. That’s a huge difference, particularly when I get off the saddle every five minutes to give my underside a break. On the 10” span when riding off the saddle, the chance your rear tire bounces out of the rollers is real. My bike wouldn’t even rest on the rollers, so that I could get on and try them out. It kept wanting to roll backward off of them. And I ride 700c x 25mm tires. Ha!
Spend the extra dough and buy Kreitler. You can then amortize the expense over at least 20 years. Can’t say that about too many purchases anymore.
