I bought a 50mm Carbon Clincher with a Powertap Pro+ from Boyd Cycling and combined it with a Garmin 500. Today was my first ride with all of that. I intended to just go out and ride my normal 24km round trip ride and see what the info looked like. At about the 6km mark I leave the city, cross the railroad tracks & typically pick up speed as there is an 8' shoulder from there. So naturally I decided to see what the next 20 minutes would look like for an FTP test. For my first attempt, and an ill-planned attempt at that, I'm pretty happy.
From this I see my 20 minute wattage is 282, so less 5% that equates to 268. I weigh 84kg so that's 3.19 w/kg. I can live with that as a start.
As far as the equipment goes, I love it. Boyd is an awesome vendor and the equipment arrived really fast considering they had to build the wheel. The Garmin is a real step up from the Bontrager Trip 2 I was used to using.
Any comments are welcome.
