43 degrees and rain this afternoon with the with at 9 to 10 MPH.
I hit Zwift for a 19-virtual-mile fast ride and fast it was. I think it was the Figure 8 Loop on Watopia...pretty flat. Not much virtual climbing.
I warmed up as my Bluetooth headphones paired, Zwift Launcher fired up and I got YouTube running with some 72 BPM trance and off I sailed from the 'spawn' area. Yes...the kiddies call it 'spawning' when you 'teleport' into the Zwift 'world'. All righty then!
I either passed a guy or a a guy passed me and we started rolling at a good clip and got faster as we picked up a third guy. We blew right through a slow group ride event that had maybe 50 riders in the bunch. One guy surged away from me and the other turned off, ended his ride or dropped behind me and I cruised on up the road and hooked up with two fast gals. One pulled ahead and the other gal and I traded off beating the **** out of each other.
A single gear is NOT the bike you want to be on when the hammer comes down on a 9% hill. I was out of the saddle and sprinting up that climb to stay with her and my heart rate was almost pegged at 181 BPM over the top. The pressure stayed on as we hit the 5-miles to go mark.
She either dropped or ended her ride or decided to warm down and cruise as I picked it up to 77-78 RPM's and pushed for home with two guys that I picked up on the run in.
Hardest workout of the week. Anyone that thinks indoor riding has to be easy hasn't been on Zwift.
Eventually I want a trainer with action like the Kurt Kinetic Rock & Roll (the software / communication interface sucks, but the trainer's mechanical action is desirable IMO. I think it's a carbon saver.
There are several 'rocking plate' designs out there. A Zwift user published detailed drawings on a very nice one that is easy to make. And there is the CoPlate model you can buy out of Europe and it's really nice too. But, there is one thing I do not like about the rocker plate designs...the additional 2" or so of lift it puts under the bike. I already get nose bleed just sitting on a conventional wheel-on trainer and use a 3" step block to mount and dismount the bike (not a necessity, but a nice feature).
I used some pretty high durometer open cell rubber about 3/4" thick under the Kurt Kinetic Road Machine trainer in an experiment to give it some float / rocking action. This is in order to get some side-to-side rock to relieve some of the stress induced into the frame when sprinting, doing intervals and climbing hard out of the saddle.
Surprisingly, it worked pretty well! Almost too well. I got some nice side-to-side motion going. It's limited as the compressed starting height of the pads was probably only about 1/2" to 5/8".
I had used a 2" wide strip shaped pad longitudinally up the center of the rear roller support as a sort of pivot point and placed pads under the two forward leg ends. My trainer sits on an indoor commercial/industrial entrance type carpeted mat and there was no slippage or movement of the pads during my one hour session on Watopia this afternoon.
The rocking action could actually be just a little stiffer so i rotated the rear pad so it now has the entire 8" or so length of the trainer bar sitting on it. Theoretically this should stiffen up the rocking action a bit. I'll try and test it out again this weekend.
I will look for more rubber sheet to play around with if I go out to Menard's this weekend. I think stiffer rubber under the two forward leg ends would be an improvement and may go to 1" thick material. That should give me a compressed starting thickness of around 3/4" and allow more angle off vertical to the rocking motion and the higher durometer / hardness will increase the force required to initiate the side-to-side action a little.
