Good point, maybe the rider is a naturally gifted descender.
the best.

I'm guessing someone who uses Campag, going touring on rough/broken roads?
and they look nice. wich is nice.

Superstar wheels are Reynolds rims rebranded; can get 66mm clinchers for £700
I didnt realise that.
Im tempted by the reynolds at £650, as it seems a pretty good deal.

I was told this at my lbs.
Maybe its not true.
Is it not down to your company's discretion?

question: what would the weight difference be between a 36h and a 32h build of a open pro > DA wheelset? Approximately?
-
• #1757
The weight of 4 spokes plus nipples, so around 30g iirc

less material removed for 4 extra spoke holes plus 4 extra eyelets

I think the question has been misinterpreted...

what hubs?
DA wheelset - 1,482g
32 spoke, alu nipples.
OP with 105 - 1,824g
OP with ultegra - 1,822g
OP with DA - 1,699g -

DA hubs

Well thats 36 vs 64 spokes. (I'm assuming C24s here)
Using CX-rays thats 28 x 4.4g = 123g
1,482 + 123 = 1,605g
So the rims must be 47g lighter a piece too.

What? Confuse.
I'm not talking about factory wheels- I meant what would the difference be between two handbuilt dura ace to open pro wheelsets: one is 36h and the other is 32h (not sure of spokes- lets just say Sapim race)
-
• #1764
Difference between an open pro rim of 32h and 36h is 5g according to WW and 0g difference between 32h and 36h Dura-Ace HB-7900 hubs
does this help?

The weight deference isn't enough reason to not get a 36h build if you need it.
Any particular reason why you want to know?
On my 105 to Mavic A319 build with ACI double butted spokes. The spokes were between 6-7g each.

It was the > that confused me.
Roughly
Sapim race are 5.7g each.
the rims are 5g heavier (4 extra eyelets).
nipples alu = 0.31g, brass = 1gSo with brass nipples (8x5.7)+(2x5)+(8x1) = 63.6g
So with alu nipples (8x5.7)+(2x5)+(8x0.31) = 58.1g -

I actually calculated the difference in spoke weight for 56mm vs 40mm rims for my last build. Then offset that against the difference in rim weight. Uber nerd alert.
These things are interesting when sat in front of the PC. But 60g difference in a wheelset is nothing in 'real life'.

I'm tempted to do a 'what if I climbed Mont Ventoux' calc for each. I bet the time difference would be a single second.
-
• #1769
ha. I am going to be climbing Ventoux with these, that's why I'm asking, sort of :)
I don't need 36h per-se, i've just been offered a wheelset with 36h for a great price and was wondering what the penalty would be. I enjoy having 36h wheels for winter, commuting and night rides - fuck you pot holes!
No way am I taking 45mm carbon clinchers up Ventoux in that wind, and I'm not building/buying a pair of lightweight low-profile rims for one climb.

I'm currently riding my new 56mm carbon tubs. around the west coast of Norway. In what seem to be the startings of our autumm storms. The wind hits you from the side as you ride along the fjord edge. Then suddenly bounces off the mountian on your opposite side. Effectively changing direction by 180 degrees.
They took me all of 20mins to get used to.
I do have good 'ballast' though.
Those 36 spoke wheels will cost you 6 seconds on the way up, or 0.1watt.

I'm no pro builder. But wheel longevity is more down to spoke tension than the total number.

Of course.
I have ample weight to keep myself on the floor, but Ventoux is notoriously windy at the top - I expect that when I get there I am not going to be in great shape after 2 hours of climbing, I don't really want to worry about my front wheel going awol when I'm at my limit... or have to deal with gusts on the descent.
-
• #1773
It'll take you mind off the suffering at least.
I guess it could be annoying having to weight the front, while in climbing position. But I would'nt think twice. My wheels were built partially with that sort of climb in mind.

All 3 times I've ridden up Ventoux, it's been less than 3 on the Beaufort Scale.
