I used to train indoors on a Blackburn, but Santa brought me a LeMond Revmaster spin bike for X-mas, and I like it much better.
The fit is infinitely adjustable, and quickly changes to suit the rider. The "Pilot" accessory monitors cadence, distance, calories, and heart rate. I was pleasantly surprised that the pilot picked up the signal from my regular chest strap.
We purchased a set of spinerval DVD's to try them out... the music is corny, but the interval load on their "Hillacious" DVD is a killer.
With our recent windstorms, snows, and below freezing temps, I haven't had an opportunity to ride outside. My 8 year old daughter keeps asking me when we're going to ride together again... She thinks my wife and I look silly on the spin bike in front of the TV.
We'll open our outdoor season here pretty quickly, with a ride called the Chilly Hilly at the end of February. It's only 33 miles, but somewhere in the range of 3000 feet elevation gain. We're working our way up to the RAMROD in July, 154 miles around Mt. Rainier, with an elevation gain of over 10,000 feet.
The nicest thing about the spin bike is that it's so quiet... anyone riding a trainer knows what I mean.
