What difference a bike makes.

So.... I was trying to explain the difference between the Steelman and the Surly CX bike to my son over the weekend. A tough prospect considering he has nothing to compare it to.

There are a few stories to go with this... like when an aunt asks my wife if artists pencils really should be that expensive, and what makes them different than the old No. 2.

Anyway, last night doing the 21min workout at Area 51, I can now quantify the difference the bike makes. I rode the Surly on the same workout I've done previously on the Steelman.

Same start as the previous 3 times... I felt great. The only difference was the tire and bike selection. Coming up on time, I noticed I was behind where I was last week... well behind. At the interval end, I'm guessing it's almost 1K difference over 21minutes. It's got to be close to a minute of effort.... all because of bike and wheel/tire selection. Too bad I didn't run the same wheels as before also.

I'll be glad to get back on the Steelman now... just so I don't take it for granted anymore.
