This is a Guest Post by Ron Fritzke, who is a cycling product reviewer with a passion for ‘all things cycling’. A former 2:17 marathoner, he now directs his competitive efforts toward racing his bike…and looking for good cycling products.
Coach Bob’s been encouraging you to get in regular off-season rides. I can say ‘ditto’ to that admonition…to a great extent what you do in the off-season dictates how you’ll do racing this spring and summer. But what do you do if you aren’t fortunate enough to live where the weather’s always nice enough to ride outside?
That’s where a quality indoor bicycle trainer comes in http://cycling-review.com/accessories/bicycle-trainer/.
If you’re serious enough about your training to have a coach, you’re most likely not going to benefit from a wind trainer. Wind trainers are notorious for being too loud, and they don’t provide enough resistance to follow Bob’s advice to “have a goal for each workout with a designated outcome”. In short, wind trainer’s won’t allow you to do the intervals that are in the coach’s plan.
Mag trainers are a bit better, particularly now that CycleOps has come out with their Magneto model. The CycleOps Magneto http://cycling-review.com/accessories/bicycle-trainer/cycleops-magneto-bike-trainer-review/ is the first and only mag trainer to supply ‘progressive resistance’. The resistance level in mag trainers varies according to where the magnets are on the flywheel.
The engineers at CycleOps designed the Magneto to make good use of centrifugal force. In the Magneto, the faster the flywheel spins the further the magnets move toward the outside edge. This increases the resistance level progressively without the rider having to dismount and change the setting by hand. This feature, coupled with CycleOps’ reputation for making quality products makes the Magneto a viable option.
In case you’re wondering if the Magneto will provide enough resistance, their speed vs. power graph shows that the unit provides over 300 watts when your rear wheel’s spinning at 25 mph.
Most serious cyclists choose a fluid trainer for their indoor riding. Fluid trainers are the quietest and provide a power curve that gets increasingly steep the harder they’re pushed. This type of trainer’s ideal for the intervals that Coach Bob has planned for you.
Until recently the Achilles heel of fluid trainers was their propensity to leak. The point of vulnerability was around the shaft that went from the spinning drum to the impellers within the fluid filled chamber. After a while the O-rings simply wore out.
When Kurt Kinetic came out with a new design everything changed. They isolated the fluid chamber from the rest of the unit, and coupled the impellers spinning through the fluid to the flywheel on the outside with the use of six pairs of strong magnets. By doing it this way, the flywheel and the impellers spin in tandem without the fluid filled chamber being breached. There’s an excellent video demonstrating this concept on my Kurt Kinetic Road Machine review page http://cycling-review.com/accessories/bicycle-trainer/kurt-kinetic-road-trainer/.
Kurt Kinetic now dominates the fluid trainer market and have added a couple of new twists in their Kurt Kinetic Pro and Kurt Kinetic Rock and Roll models.
The ‘Pro’ is essentially a Road Machine with 12 extra pounds added to the flywheel. This added weight supplies additional inertia, making it more difficult to ‘spin up’ the trainer. The rationale behind this is that it more closely simulates the effort it takes to accelerate out on the road.
The Rock and Roll is an interesting unit. The entire trainer can rock back and forth as the cyclist pedals. The advantage with this unit is that it alerts the rider to inefficiency in their cycling technique. If there’s any mashing or asymmetrical pedaling going on, the exaggerated rocking of the Rock and Roll trainer will make it known loud and clear.
While I’m sure any of you who’ve been under Coach Bob’s coaching for any length of time already have a suitable bike trainer, I hope that this short article has added a little bit of information about several of the excellent new trainers in the marketplace.
