Ultegra / open pro wheelset weight?

kevin_stephens

I like my handbuilt wheels, ultegra hubs, open pro rims, 28 plain gauge spokes, alloy nips.

But I am taken with the idea of getting something lighter for hilly sportives etc (poss with a wider range casette) when I have gained enough fitneess.lost weight enough to feel I have earned tham - keeping ultagra/Op for training

I like the look of the Easton EA90SLX (Ascent) (I weigh 145 lb)

To save me the bother of removing my casette, tyres etc, can anybody tell me the weight of the Ultegra/Op wheels to compare with the quoted weight of the Eastons?

Thanks
Kevin

About 1690g with DT Revolution spokes which are about 150g for 32 spokes. Ex rim tape and skewers. It would be easier to subtract the cassette, tyre and tube weights (or just cassette weight if you weigh when changing tyres anyway).

Not ridden the Eastons but I like Neutron Ultras at about the same weight and price point FWIW.

Thanks James

That's around 220 g saving, most of which I guess wil be in the hubs so not a lot of rotational inertia - I think I'll keep my money instead

The weights I got when I was looking to buy a set was :

Front 870
Rear 1080


A bit more than James was saying but a lovely set of wheels.
If you are running 9 speed check on compatability as some ultegra hubs are 10 speed only

Also - in danger of sounding obsessive, but weighing wheels is actually quite difficult

Too heavy for the kitchen scales, too light for the bathroom scales-whole-bike-method

Hi there.

The pair I built last year (or maybe the year before...) were 1800g for 28 hole, Ultegra hubs, DT double butted spokes (why would anyone use straight gauge?).

My kitchen scales go up to 1000g, so with a bit of careful balancing they can just about cope if you weight one wheel at a time!

Cheers, Andy

the other better option is to buy a lighter tyre and tube and save on rotational weight. it will let the wheels spin faster and more freely

There are some inner tubes on ebay at only 67gms weight which is over 100 gms less than most types . Save another 100 gms on some new tyres and you're there

Maxxis Ultralight Road Tube 700cx19-23 Presta 51mm

you could probably find some Dura-Ace 7800 hubs cheaper now the 7900 is on the horizon and they'd be lighter than the ultegra.

I have a pair with DT revolution spokes and DT RR1.1 28h rims... v.light and reliable.

If rotational inertia was at all important, that might be an issue - but it's not!

Only the ones which come in complete wheels, so not an issue (though the older 7800 DA ones which are being recommended are 10-only).

Indeed - particularly with only 28 spokes and alloy nipples which implies an attempt to save weight!

My kitchen scales go up to 1000g, so with a bit of careful balancing they can just about cope if you weight one wheel at a time!

My kitchen scales go up to 5kg - I thought 3kg or 5kg was quite normal.

Which is a good idea if you like fixing punctures - personally I reckon 75/80g tubes are about as light as you can go and still get reliability.

i dont rate those maxxis tubes at all.
they would last me one maybe 2 rides before they developed tiny tears and went down.

went through 5 in a month, changed to heavier specialized tubes in the end and they never blown.

well done aracer you have managed to put every poster's nose out of joint in a single post
interesting observations just a pity your post comes across as rather arrogant and opinionated

yes they are entirely unsuitable for training racing or anything really save maybe short TT and hill climbing and then you would probably want to use tubs anyway. It was said `tounge in cheek' really :roll:

Hi there.

Didn't upset me...

Why don't you play the ball and not the man!

i.e. If you disagree with what's been said then address the points and let us know where aracer was going wrong?

Cheers, Andy

keep your nappies on chum.

No need to throw all your toys out of the pram :roll:

I used smilies to show it was tounge in cheek. Obviously such subleties escape you

Hi there.

Putting in a smiley doesn't change what you write. If you're going to insult someone, just have the balls to go ahead and do it!

What's the point of typing something, then saying "I never really meant it"? It's been said already!

Cheers, Andy

aracer

Thanks for the support, Andy. Not that I really need it, as I am arrogant and opinionated, and try and make a point of emphasising those qualities in my postings on here. The thing is I'm also more often than not right

Andy I have already explained what I intended ,I don't understand why it is that you are unable to accept that and move on. . I have not insulted anybody.

If you do not understand the purpose of smilies I suggest you do a quick google refresher

You are clearly trying to incite an argument and I can tell you that you are wasting your time.

I managed to get hold of some super acurate fishing scales

Ultegra, 28 spoke, open pro, front 760 gm (830 gm inc QR)

According to Shimano, rear hub is 347 gm, fromt 140 gem, so rear wheel is 1037 gm inc QR

Wheelset weighs in at 1837 gm inc QR
It hardly seems worth it forking out for the Eastons to only save 270 gm
