Rolf Vector Comp Wheels + Computer = problem(9 posts)

Rolf Vector Comp Wheels + Computer = problemRiding ButWhoKnowsHowFast
Apr 30, 2001 7:02 AM
I bought an Avocet 35 computer for my new bike but the circular magnet won't mount on the rolf wheel. Am I doing something wrong or are Avocets incompatible with Rolf wheels? Can anyone recommend a computer that will definitely work with Rolf wheels?

Your Trek dealer should be able to provide you with an adapter for the bladed spokes. I was provided this information by Rolf. Check with your LBS.

Stop in your LBS and tell them you need a magnet to fit the bladed spokes of the Rolf's. I did and they handed me a special magnet free of charge.

If you have a drill, do this. Just drill a hole (at least width of spoke) at the bottom of the slot where the spoke slides in. Done.
Just slide on magnet and once it gets to the hole it can turn easily for any direction.

The slot on side of magnet should look like this:
O = drill hole
- = slot

Any magnet will workDean

Any magnet will work with your computer, you just need one that fits bladed spokes. When I bounght my Vector Pro's I got a magnet designed for bladed spokes for a few dollars. Call your LBS.
I, too, have rolf'sDT

...and I just put the magnet down near the hub, where the spoke rounds out, and it works great.

Thanks for the replies everyone.

It sounds like some of you think that the Avocet 35 uses the usual spoke-attaching magnet, tightened down with a set screw. Not so. This thing is different. It's disk shaped and supposed to go over your axle, with little plastic hooks that grab your spokes. The magnet part is circular, too, kind if like a silver dollar with the center drilled out of it, and it fits in the plastic disk. I've never seen anything quite like it.

Also, I called my LBS, and they said, "Oh yeah, that's a problem. We might be able to rig something up." You know, for $40 I'd really rather not get into rigging something up, especially since it was for a brand new bike. I think I'll get my money back instead and get something else, and ask the LBS to show me how it mounts on Rolf wheels, just to be sure it fits!

Geez, I thought this was going to be easy...

I'm not sure about the Avocet computers, but about every computer I've used - Avenir, Vetta, Sigma, Cateye, all could get by with a standard metal "button" magnet - I.E. the round type with a small set screw on the back. You might want to check if the Avocet would also.

I simply mounted a button magnet on the top of the Rolf bladed spokes where they're round and mounted the sensor high up on the fork.

I then found that the Rolf has more lateral play then my standard wheels and had to re-set the magnet to an opposite side spoke, with
the grey magnet side still facing the sensor. Still worked and I've never had a problem.

My LBS confirmed that this computer isn't compatible with my wheels. He did an even swap for a Cateye Astrale, which really does mount on Rolfs.
