Other company's hub weights compare to Shimano?(10 posts)

Other company's hub weights compare to Shimano?off roadie
Aug 14, 2003 7:32 AM
I recently built a back wheel that came to 962 grams (sans skewer and rim tape) using a Shimano 105 hub. I didn't wiegh the hub first, and Shimano only lists weights for the 105 WITH its skewers, while most companies list weights without. It can even be tricky comparing Shimano hubs, since they come with diffrent skewers.

How does the 105 compare to other hubs in plain, no skewer comparison? I'm guessing my wheel could have been lighter I'd I'd paid for a fancy hub, but maybe not by much? Its already lighter than a Cosmic Elite or Kserium Elite, which seems amazing for a wheel that cost $120 or so in parts. Given that its likely got more mass concentrated at its center, it probably has a much lower rolling inertia than either as well.

For the curious, the rim is Velocity's new Aeroheat assym, and the (32) spokes are Wheelsmith DB14 on the right, XL17 on the left, with brass nips right, alloy left. The rim is suprisingly sturdy for its 400g weight; it is entirely stable with the right side tension over 120kgs, which puts the left at 90kg or so.

The Q/R is probably around 120-130 grams.

you serious? A pair should weigh about that much...!
DOH- I could weigh the roadie

And subtract that from Shimano's listed weight. If the rear QR alone really is 120+ grams, that would make the 150 rear 290 grams, which sounds about right. Not really so bad then- seems that a lighter hub would have saved me 50-80 grams at most of (basically non rotating) mass.

Many of us here have been trying to tell folks that a well constructed handbuilt wheel can be as light and strong (or lighter and stronger) as an expensive factory wheel. Sorry if it annoys some people, but it's true. Sounds like you have a nice wheel there.

I haven't weighed the 105 freehub & skewer, but I have weighed an Ultegra 6500. Hub was 346g, skewer 63g. The 105 freehub weighs practically the same – Shimano shows the weight with skewers to be 410g for Ultegra and 411g for 105.

In order to save weight on the hub, the next step up would be a 312g Dura Ace ($100). If you are willing to pay $200+ dollars for a rear hub, the Hugi or American Classic weighs around 240g. -Dave

The only rear hubs that weigh significantly less than a Dura Ace hub use an aluminum cassette body. While Al is lighter, it's less durable in this application since the cogs can dig into the sides of the splines.

For weights, check the following link:

Dura Ace 7700 - 315 grams (w/o quick release)
RX-100 (similar to 105) - 348 grams (w/o qr)

Not that I'd care to take appart this wheel and put in a new hub, just curious as to how much lighter the chi-chi stuff is. An AL freehub body hardly seems worth is, especially as I run some bigger loose cogs. I thought they used TI for lightweight freehub bodies, to avoid so much damage.

Dura Ace rear hub uses a Ti cassette body. I think this is the main reason it cost so much - downright cheap though compaired to most designer brands.

Unless by "you" you mean the whole board. I've been building my own MTB wheels a while now, and they work great. This is just the first lightweight road wheel I've done, and the first wheel I used a tensiometer on from the get go. If I can build a wheel that matches quality factory specs, probably anybody can.

I'm already working on a matching front. 32 XL14 spokes, alloy nips, ritchey aero pro rim. The hub (rx100) was free, just have to pull it off a dinged rim. Cool thing is, it uses the same spoke lengths as the back, laced 2x instead of 3x. Makes it very easy to buy spokes!

In the store they were $22 a couple of weeks ago...

The are 83 grams total for front and rear. I think mine were like 43 for rear and 40 for front. I put these on my training wheels that had rx100 hubs and dropped 103 grams from the wheelset. The skewers weighed in at 186 grams for front and rear...

The DA skewers weigh around 120 for front and rear.

go to

and this will show you the weights of most hubs w/o skeweres as well as the skewers.
