Ultimate 4-season Hybrid City Bike 2.0 - New Front/Rear Specific Mavic Wheels!
"Test everything; hold fast what is good."
1 Thessalonians 5:21
Got me a pair of Mavic wheels to replace my heavier Xero Lite and WTB Dual Duty/Shimano wheels!
Front wheel: Very fast/aerodynamic, light, solid with a maxtal sup alloy rim w UB control for excellent braking and yes, drop-dead wicked looks is the Mavic Cosmic Carbone SLR (approx. $400+ new. I found this gem for $230 used and topically damaged)! Over 120g lighter than previous Xero XSR-3's and wayyy more aero. I'm faster already!

Rear wheel: A good old reliable, fully n easily serviceable and parts replaceable, steel spoked, yet still very lightweight (860-875g) all black, all alloy and very cool lookin 2011 Mavic Ksyrium Elite. 130-200g lighter than previous WTB Dual Duty/Shimano Deore/14g spoked wheel ($200 used from Kijiji)
My face when riding it (priceless)!

Oh, also managed to finally salvage my first USE XCR carbon suspension Shokpost thanks to USE's $10 service kit. Now I have two, one for my road race bike the other for this one.
Good to have continuity:

$157 Full Carbon Rim Tubular 700C Wheel - 530g
Third wheel I've purchased direct from an Asian manufacturer/seller. This one was from Shanghai via eBay.com.
So far, so good. The first wheelset I never rode because it was for a special fundraising build but, I did receive and install them on the bike with no problems. They were fully and professionally well-packed and sealed. Nothing fishy. Just as you would get it if ordered new from a local supplier like Live to Play, OGC, etc.
As was this front, 700c carbon rim tubular wheel. Full UD carbon matte finish. Aero/bladed spokes, Novatec sealed bearing hubs with minimal shell and flanges. All black. Claimed 530g w/o skewers. $157.25 + 50.00 shipping CAD. Received it in about 9 days! Very impressive. Unbeatable price, even for the most killer deal from a used equivalent and even compared to my inside bike employee discount...you cannot get a better deal than this. Period.
Here it is, straight outta the box:

Bicycling / Cycling Efficiency / Performance ! :O Thank GOD
Hmmm what else shall I write about as an adult Christian-Chinese-Canadian-Torontonian 4-season cyclist... How God has given me this opp! Yes! He rocks! Therefore we rock! "Because I (Jesus) live, you will also live" John 14.19 :O Woah. That's BIG. Only God can say that and back it up, eh? ;) Love Him.
Thank you Loooord for bikes. Bikes being by FAR the most efficient means of transportation. Period. I am talking worlds more than ANY other vehicle incl. cars, jets. even any animals.
This was proven and documented by Richard Weber at some university (I recall Duke or somewhere on the East coast of U.S.). Google it. Absolutely awesome. No wonder there is that special something that happens when you bike...yeah, it's called YOU workin in perfect harmony with a MACHINE to acheive the most efficient thing in existence!
http://en.wikipedia.org/wiki/Bicycle_performance :
"A bicycle's performance, in both biological and mechanical terms, is extraordinarily efficient. In terms of the amount of energy a person must expend to travel a given distance, investigators have calculated it to be the most efficient self-powered means of transportation.[1] From a mechanical viewpoint, up to 99% of the energy delivered by the rider into the pedals is transmitted to the wheels"
BOOYAH
RIDE ON.
