Pretty Cool: Turn your normal trainer into an power reading and RECORDING! machine:


This is what one of the leaders in powermeter market will be releasing next year


It will provide the most accurate 360 degree power measurements; a pure performance based pedal-power-meter.




Cycleops heartrate powermeter will be using an algorithm using data from hundreds of riders to use hr, cadence to estimate wattage. If enough data is used in combination with the ramp test required for the individual rider to do at a testing center with a powerbeam pro ergometer, then having the proper conversion factor of hr and cadence sent to the hr strap unit, this could be pretty awesome. and only $200. No torque value, so not accurate, but a cool estimate.

See graph below to see that new Tri shiv is not more aero than the TT shiv. The Tri shiv will fit you, where the TT shiv will not fit most people out there due to lack of adjustability. The TT shiv was successful because the nosecone smoothed 15-20 degree yaw angle wind flow better than anything to date. The Tri shiv got rid of the nosecone to allow for better ease of brake adjustment while exposing brake cables to the wind. The Tri shiv has a very, very non-UCI legal downtube. The surface area behind the headtube on the Tri shiv is the same as the surface area of the nosecone+headtube of the TT shiv.

If we head to the windtunnel, I’d like to test the TT shiv, Tri shiv and then the Tri shiv with the nosecone from the TT shiv. … and then throw in a Cheetah, Hotta, Plasma 3, Felt DA, QR Illicito. and then choose the fastest one to race at Rev3 Quassy and get it under 17 lbs.


Awesome Ritz quote:

“I realized that I like training, I like to be fit. I like the everyday satisfaction of having done something that most people can’t do. It was something I missed a whole lot. So I really do enjoy the training. I don’t particularly like it when I’m out there doing quarters (400s) and it’s super hard, but I like the satisfaction of having done it every day.”
“That’s what sometimes separates people who always run and always train and people who maybe move on in life and do something else. I think I’m a lot more likely to be someone like Joan Benoit (Samuelson), who keeps going forever, just because I actually really like it, as opposed to someone who stops and never runs again.”
- Dathan Ritzenhein, talking about his injuries and time away from training and how it made him realize how much he really enjoys the process. Too many people take training for granted until they can’t go out and do it anymore.

Awesome opinion on Ryan Hall’s Chicago performance

I really, really like: Shimano may also be finally moving on from their long-running 24mm-diameter Hollowtech II bottom bracket spindle design. In fact, we’ve been told that they may actually be adopting FSA’s new BB386Evo standard, which would certainly help lop off some weight as Shimano would then be able to move to a larger-diameter, relatively thin-walled aluminum spindle.

And, they might as well throw in a magnetic bottom bracket (see below):

and use that magnetic idea in their own shimano hubs with this free-hub body idea to make the casette lighter and easily fit the 11speed cassette:

and then make a road rim with no braking surface = super light, more focused on aero. carbon clincher

New Garmin… hits it out of the park:

Incorporates the Finis Swimsense technology, barometer for accurate elevation change, 20 hours of battery life, slim profile, power with right/left leg power….

OK, with a barometer and speed/distance, just add a running power number folks!!! and you have the best watch available.


I dig it: as ridiculous as it may seem, I like this for riding with the significant other! figure out the wattage spread vs. gear selection on this wheel and train away.

Ridiculous: If men can use pace makers, women should be able to also, regardless of the gender of the pacemakers. 2:15 is the best running record in history. I can’t believe they are going to take that away. Paul didn’t even draft off of her pacemaker like Haile did when he had six pacemakers in Berlin.

Nick’s Mt. Mitchell ascent: 

I climbed from the intersection of Curtis Creek and the Blue Ridge Parkway up to the top of Mt. Mitchell yesterday and followed it with a good trail run. The ride consisted of a 20min warm up and then the 38min effort to the top. Previous day: 30min at 5:25-5:35 pace. Today 8 x 400m holding 70sec. Saturday: Rob’s Hill Ride (80 miles with 8,000 fit of climbing!)

Normalized power for the 38min effort which was 321 watts.

Bike Fit Talk:

Crowie’s 2011 bike position on the bike

Bike fit write up from 2009:

Here are some thoughts/a rant on bike fit, looking at Craig Alexander’s
position as he won Ironman Hawaii this past year.

Here is an image of Craig riding in this year’s Ironman Hawaii

Here are Craig’s numbers for a bike fitting he had done by a bike fitter using the 3D motion capture system, Retul. 

While Orbea offers more forward positioning with a different seat post, Retul folks chose to shove his saddle all the way forward and called it good. From my experience and from what the Fit Institute at Slowtwitch has found after hundreds of bike fittings, a hip angle closer to 100 degrees typically allows a fit rider to put out maximum perceived power and achieve maximum comfort.

Retul is a very powerful fit tool, but in this case, it may have pointed out
flaws in the fitting process. Craig is a sponsored athlete and, unlike the rest of
us, he doesn’t get to use his bike fit data to help him make a better bike
purchasing decision, but has to use the bike given to him by his sponsor. Another sign
that his current bike and/or chosen seat post is not the best choice for him
is that he has a healthy 15.9 cm of hip to elbow vertical drop but still has
a ton of spacers under his stem. He may be better off with a bike that has a
higher head tube height. His hip to elbow drop is not overly aggressive by
any means and is actually on the upper end of drop among fit athletes, yet
he has a super compressed 90 degree seat tube angle. Again, he would most
likely be better off further forward over the bottom bracket/crankset which
would open up his hip angle and allow him to increase the drop between his
hips and elbows/saddle and aerobars and then, maybe, the Orbea would be a
better choice for him and he wouldn’t have a foot of spacers under his
stem. (see 2011 Shiv set up with much more open hip angle)

That image of C. Alexander was from a slightly odd angle, so here’s a direct side view showing that there is no issue with the distance from his knee to elbow, but you can see his seat crammed all the way forward, the compressed hip angle and the 3 inches of spaces under his stem which I wrote about before.

Another interesting fitting critique is of Contador in the final TT in this past year’s TdF. His position was great, but watching the live feed, he was sliding forward a cm or two ever couple of minutes and he would have to push himself back up on his saddle. Towards the end of that 40.5 km TT, the frequency of this shifting on his saddle increased to every 5-7 seconds. The energy and power spent making this correction, over and over again during a 40k could not have been efficient. The cause? I’m not sure, but I doubt the all carbon saddle he was using helped too much. He wasn’t riding the nose of the saddle as most time trial experts and experienced triathletes do, or how he himself has ridden in the past (see photo here)

During that last TT, he was lying across the entire saddle, which isn’t all the comfortable (see photos here and here). (note how you can seen a good chunk the tip of the saddle from this front view, not something you could see if he were on the nose of the saddle)

But then again, in the first photo of Contador on the ‘zebra bike’, he’s on that same all carbon saddle and in a great position on the nose. In this year’s TdF, he started off on a Trek TTX and then later switched to the aero/tt-industry-leading Trek Speed Concept frame seen in the two above photos. This could lead to the conclusion that his new bike didn’t fit him properly and that the carbon saddle was not the issue due to his taint of steel. But looking at his greater than 105 degree arm angle in that final TT, it looks like the bike was set up great for a tt position where he would have been on the nose of the saddle, as seen in the zebra bike photo, but in this final 40k TT he was pushing himself back to stay as far away as possible from the nose of that all carbon-no-padding-in-sight torture device of a TT saddle. This requires an understanding of the Hows and Whys of riding on the nose of a saddle when in the TT position. Why? because sitting on the back of the saddle would crush soft tissue when down on the aero bars – not knowing how to ride on the nose and crushing this soft tissue is the number one reason why aerobars get raised up and up and up in an attempt to find a comfortable position, when the real problem is saddle choice and knowledge of how to ride the saddle. How? When sitting in a road and mtn bike position, we sit on our ‘sit bones’, when we roll forward to a TT position, our sit bones are no longer in contact with the saddle and an experienced tt/triathlon cyclist will choose to sit on the bones that sit to the side of the soft tissue area. On a normal saddle with a single point/nose, the rider chooses one of these bones, choosing one side to hang to. Some cyclist will slightly turn the saddle in one direction to compensate for this. With aero seat post that can’t turn, the best solution would be a shim at the seat clamp. In the past fiver years, a couple of saddles have appeared (ISM, Cobb) that allow both of these pelvic bones to the side of the rider’s soft tissue to be supported, so the rider can sit dead on and not have to choose one bone over the other.

Here’s a photo of Cancellara  from that final TT showing great bike fit and riding position.
