|Rolf Vector Pros v Shimano WH7700||Citius|
Jul 10, 2001 6:10 AM
|I'm in the market for a semi-aero clincher wheelset and have narrowed the choice down to these two models. The shimano set is a bit lighter and, through my LBS, a bit cheaper. What are the other differences between these two wheelsets? Quality? Design?
The spoke patterns are almost identical. I am a larger racer -220 lbs- so stiffness is very important.
At this point I prefer the Shimano's (Japanese) but feel guilty because it looks like they copied the design of the Rolf's (American).
Any knowledgeable input would be appreciated. Thanks.

|I am also a heavier rider at about 230, and I love my Vector Pro's. I have had no problems with them in abotu 500 miles. I do not know anything about the Shimano wheels.|
|Are you sure about the weight?||Jim Burton|

|I could swear that I read the Shimanos are heavier...|

|Specs by both manufacturers and the Damon Rinard site state that the Vector Pros are 80 - 100 grams heavier than the Shimano Dura Ace's.|
|By 15 grams...||PsyDoc|

|Shimano: front: 720 g., rear: 975 g. Total Weight: 1695 g. |
Rolf Vector Pro: front: 750 g., rear: 930 g. Total Weight: 1680 g.

|I ride Vector Pros. But my LBS sells and services both. They say that the Shimanos are harder to true than the Rolfs.|

|The problem with low spoke count wheels is they take away spoke weight, and add rim weight, further outwards in the wheel. |
You'll be better off with a stronger, lighter, and cheaper wheelset built up with normal stuff. DA hubs, revo spokes, even with a box style rim like an Open Pro would be better then both of those wheelsets. Even a Velomax wheel would be money better spent. The circuit comp seems to be pretty similar to what you want. It's over $100 cheaper then Ultegra wheel and is lighter.

|Well, maybe in the case of full retail but I got a set from eBay for under $500 (delivered). Granted it took a while of trying and several bids, just figure out what your MAX is and let 'er rip.|

|i think rolfs are made in germany, or at least a german company|

|Rolf wheels are made by Trek. The inventor, Rolf, must have sold to Trek and entered into a noncompetion covenant. His web site now just points to Trek and have a look at http://www.freewheel.com/rolf/prototypes.htm where he displays projects he is working on for 2002.|

|I heard that Rolf and Trek had a problem with each other. But no one says why. Nevertheless I hope that Rolf keeps going on building his wheels, because they are really good. I had the vector comp's, never had problems with them. Recently I rode the sestrieres, its just great how light you can go up an hill with them!|
|Hub Weight v Rim Weight||Citius|

|They are comparable in terms of overall weight, but the Shimano wheelset seems to have more weight concentrated in the hub rather than the rim - with spokes being threaded into the hub. The Rolf's spokes are laced into the rim. It looks like the Shimano wheelset would have less rotating mass. Does anybody know if this is true?

I had the chance to ride DA 7700? this spring for about a week. In a blindfold test, I could not tell the difference between the Rolf Vector comps and the DA 7700. Yes the hubs "felt" smoother on the DA's but on the same course that I ride alot, I could not tell the difference. I had to go by time, not ave speed (no magnet of DA) and it was about the same. In my conclusion of the test, I would not run out and buy a new set of these wheels, Shimano DA or Ultegra, my wheels felt just as good. I have read somewhere the theory/reason for spoke nipps to the hub are more weight to the center as opposed to the rim, faster spinup.

|I´ve once tested the Shimanos (in the Ultegraversion, which has only slightly different hub,anyway, the impression should be the same) and it was one of most joyful rides i´ve ever had when I was back on my usual Ksyriums. The Shimanos have very high vertical stiffness, infact way to high: They made me feel my OCLV 10x harsher than my quit harsh Cannondale (I weigh 180 lbs.). But what I really hated was, that in contrast of the vertical stiffness, these wheels have absolutly no lateral stiffness. I could easily, without force, push the Rim to the brakes (!)
On the other hand, I cannot tell that much about the Rolfs, I´ve only ridden the Vector Comps once. I could hardly find any difference to a normal wheel, but it was very short so I couldn´t check anything about aerodynamics.
When I tested the Shimanos, I participated in a big demo-program of Shimano all across Europe, almost every third store has them to test for weekend. I don´t know if there´s something like that back in the States, but it would be definitly worth trying those.
