Winter training with Kanetic

Does everyone use the recommended wheel circumference '2060' or have you measured it accurately. Mine back wheel circumference works out at 2113

Sure, lots of folks do just that. It means two wheels, both with mounted cassettes and appropriate tires mounted. Nothing wrong with that approach if you live somewhere warm enough for a bit of outdoor riding but ride indoors as well. You can also just go with one tire that works well on a trainer, keep it fairly clean by wiping off road oils with rubbing alcohol before using it on the trainer and just know it will wear a bit faster. A slick road tire works best on trainers. Personally I use older tires that I don't feel comfortable racing anymore but still have a lot of life in them. I keep them clean and use them as trainer tires. When I run out of those I'll probably check out a specialty home trainer tire.

What sort of riding do you do? Long tours, club rides, races, triathlons, centuries? The Shimano R6600 wheels that come stock on the Ruby Expert are decent wheels. You could get something lighter or more aerodynamic but it depends on what you'll want to do with the new wheels and how much you're willing to spend. You'll find a lot of threads discussing wheel choices in the Cycling Equipment forums: http://www.cyclingforums.com/f48-cycling-equipment.html but you'll also find a lot of conflicting opinions.

Good luck,
Dave

Measure it, don't use the generalized estimates. Did you measure it with a rollout test while sitting on the bike with the tire pumped up to the appropriate pressure? That's the best way to get a good circumference measurement. FWIW my road tires tend to be close to 2090mm when rolled out in a loaded test. These are 700x23c Michelin Pro 2's mounted on various rims and I weigh ~72kg right now.

thanks for that Dave. I forgot to sit on the bike originally so I just re-measured the circumference - its now 2108. I managed 272watts for 80mins this morning. However I forgot to stand up so my butt is very sore now
