What was the starting weight of the wheelset?

And what did he do to them to achieve the weight loss?

For me it is strange that you make a super light project and not using these components from the begining..
But yes it is a great set and I would love to see them go in production!

Just an observation. I was on that website yesterday, of course they were talking about all of these superlight and superexpensive parts. What tickles me though, during some group ride pictures were taken. We all know picture tell a thousand things. You can tell most of these didn't ride that often, beergut, lack of tans, etc. It just seems like most of them were posers, for lack of a better word.

The people who can afford to buy this stuff retail, or the ones who have access one way or another to exclusive, high-end bike parts don't ride. They just "talk about it". :roll:

Two things...

firstly... I ride.

I'm not a Tour threat... But I'm not off the back of many groups not making a paycheck for turning pedals.



Secondly... while I FULLY agree that there are bikes that go past light to the point of useless, I draw the line at slandering people who have a passion for the sport and the gear.

Lots of pros ride bikes worth quite a bit less than most people at this forum, but despite the fact they have less fat and turn more miles and could basically ride away from 99% of us here at will, they don't stop in and take a piss on us for who we are or what we ride...


I'm not a fan of going over the top with gear... And I have no problem challenging those that would imply their bikes are "rideable" to define the word more carefully.

But there are several guys who just have a love for this stuff and make no excuses for their "weenieness" and no exagerated claims about their gear.

To them I've never said anything but "salute".

Just because it's not for me, or "maybe" they're not at the same or better athletic level doesn't make them any less a bike lover than anyone else.

I'm pretty sure that all except two of the expensive bikes (retail over 4K$) my LBS sold this summer have less than 1000km on them. And that's ok because owners of those bikes are happy and go riding as often as they can. They just want to have good equipment even if they don't ride much. I would like to see people riding more and racing more as the local racing scene is not very big.

I must admit that I'm bit jealous to these guys who ride bikes that are 2-3 times more expensive than mine. At the same time I'm happy that I can ride at all as I've been un-employed for over a year now.

I fully agree with the statement of Pez...
We all share the same passion and there is no need for minimum Kilometers per year nor for a maximun body weight to be passionate.

A bon entendeur salut!

What a terrible generalization that is.

Can I ask why you're even on this site if you feel the need to bash people who appreciate these products?

It's not about the miles- it's all about the smiles!

+1!

Please, let's keep this civilized. Sure, there's always a big difference in what different people define as 'Nice to Have' and 'Need to Have'.

I'm not really that fit anymore, and I probably look like someone who could eat Michael Rasmussen for dinner (chicken, good). I do kick out a mean sprint once in a while though. Anyway, do I have the ability to push my relatively expensive bike to its limits thus maximizing its potential? Definitely not. Do I love every minute of riding it, cleaning it, polishing it, making new parts for it and whatnot? Definitely yes. So go ahead, make fun of me being the last fat arse up the hill. I'll still smile at the top.

thing is these weight challenged, un-athletic bike fans subsidise the prices that the finely-honed, Michalangelo Adonis types pay for their parts. Not to mention that some of the innovators of parts,frames and clothing may be older and more sedantry than the racing snakes, so where would you be without 'em.

I wish sport wasn;t so elitest sometimes....... we're all bike riders ergo good people :D

It also appears he lightened those bearings by taking out the seals :?

Since it's full ceramic and the wheels don't seem to be ridden(no glue, no tube), it's not a big problem.
