So I currently own a set of boyds and I came across a pair of Dura ace 9000 c24 clinchers for a great price. Not sure if its worth picking up. I currently race on the boyds and use them for everyday rides. Wondering thoughts on if the Dura ace will provide any advantage on the hillier rides and races. I would probably use my boyds for crits. thoughts? waste of money to own the two sets?

Guess it depends how great the price is. A backup set is always nice if you have space to store them. Maybe you'll like the c24 a touch more.

I have both and switch them between bikes every so often, it's nice to have a second set of wheels. Note the C24 have a more standard rim width than the wider boyds.

dtrain

His Boyds aren't wider (Vitesse). Do you have the Altamonts?

Gjc985

Do you notice much of a difference between the two wheelsets?

Gjc985

the big thing I am looking for is to notice a difference when climbing

Nebby10

Bikerumor Vitesse article:
Shimano spec for C24:
I really like the C24's for climbing and the difference in weight is noticeable when switching the wheels around. To me, the C24's feel a fair bit snappier and quicker to respond, but that's just IMHO About the only thing I don't like about them is the relatively narrow rim width, as I prefer wider rims in general.

I have the C24, they are very light, great for climbing, but definitely not aero. Not sure their weight limit (I am 160-165 and have ridden them for thousands of miles with no issue and they have stayed true). One great thing is they can be run tubeless.

My bad - thanks for the info. I guess it depends on the year of his Boyd's, as that article refers to it as a new/latest offering. I don't believe the Vitesse rim was that wide before the 2012 model (much more traditional, likely narrower than 20.8). I thought the width was only changed with the redesign and name change to Altamont (24mm wide) in 2013 or 2014, but looks like I was wrong there as the Vitesse had a redesign late in its lifecycle.

bianchi10

my 2012 vitesse was a 19.XX if I remember correctly.

dtrain

I'd gather that means it was actually a 2009-2011 version? I mistakenly thought that was the spec until Altamont replaced Vitesse. Nebby10's wider Vitesse set might be somewhat rare (last year or 2 of a 4-5 year run?).

Dunbar

The Vitesse uses the Kinlin XC-279. The new Altamont is proprietary to Boyd.

What's the weight difference between the C24 and Vitesse - 150g? That's not a lot.

You guys are making me all nostalgic with this thread. The Vitesse made the transition to the wider rim at the start of the 2012 season and was 23mm wide. Until late 2011 it was a standard 19mm width.
In 2013 the Vitesse changed to a new hub set and was around in that configuration until the end of 2013.
The Altamont came out this year and was a completely different rim and hubs again. That is the 24 wide 30 mm deep rim.

dtrain

From that 2/2012 Bikerumor article:

"Boyd Cycling’s new Vitesse wheel set comes with a with a 23mm wide, 28mm deep alloy rim of their own design...
Boyd Johnson has been building wheels since September 2009, but this is his first set with a rim of his own design."

...but, yeah, the depth screams XC-279.

I have been thinking about a second set of wheels (current set is DT Swiss R440, 240 hubs 28/32 I am 195) and the Altamont, 9000 C24cl, and a couple others are on my short list. The Altamont might be more aero than the C24 and that could make up for the weight difference. One event I have in mind for this alternate wheel set is a long day of climbing (5-8%) for over 10000 fee, so I am not sure if weight or aero is more desirable for that event. Any thoughts?

I wouldn't call them similar. DA is much better. Get them.
Having one set for training and better one for racing is good idea. You are also covered in case of damaging something.

I have a C24. Best for climbing as it's so light (sub 1400g). I'm also 165lb and have already put 2000km on it, zero issues yet.
