Not sure what to call this post. It’s not really going to be a review due to having just put the part in yesterday and not having much end-user experience. It’s not really an install. It’s more like photo whoring. Yes. Photo whoring of my new quick release!
Works Bell QRS - sorry for the lack of toy helpers.
Not bad eh? This is what you get in the box: both halves of the quick release, bolts to attach the boss-side, a matching wrench, a horn ring, and a set of ring terminals (not pictured – doh) if you want to make more of the 5 wire terminals active.
Back on the topic of photo whoring. I’ve been researching steering wheel quick releases for a while. The thing I’ve noticed a lack of is photos. There are lots of opinions. There are a few measurements. But there’s NEVER enough photos. So, I present way too many photos of a very small part – the Works Bell Rapfix Quick Release Spacer mark Two (QRSII).
The hub-side of the quick release.
The wheel-side of the quick release.
Not bad eh? The QRS is all metal. Some other versions of this slim-style spacer use a lot of plastic. None of that for Works Bell. Seven ball bearings help lock the wheel in place. And the ability to have FIVE circuits going through the steering wheel is a little bit impressive to me. All of my horn buttons require only one.
The boss-side of the QRS (the side that attaches to the hub, also known as a steering boss) has the standard 6-hole Momo/Sparco pattern. So if you have a Nardi-only hub, you’ll have to take care of that. The Daikei hub that Sharka wears has both Nardi and Momo patterns, so I’m good. The wheel-side of the QRS features both Nardi and Momo wheel bolt patterns.
The official measurement of this part is 26.7mm thick. We’ll take the tape measure to it once everything is in place and see just how thick my personally installed version is.
The Install
Connect the 1 wire...
... align the QRS like so, and bolt it on.
The install is half over already!
The quick release grounds through the steering column, so you don’t need to worry about a wire for that. In most cases, you’ll just need the single connection for the horn button. That’s all I needed.
Notice the marking at the top of the QRS. That hollow triangle is the 12 o’clock mark for when the wheel is released, or “OPEN.” You line the bolt hole directly below that mark up with the top bolt hole on your hub. The V made by the five wiring connections should be pointed down.
The bolts must NOT poke through the wheel side.
If you’re using a Momo wheel, you install the included horn ring between the spacer and the steering wheel. If you’re using a Nardi wheel, you leave that horn ring out. Simple, eh?
Also, make sure the bolts do NOT poke out the back of the QRS wheel mount. If they poke out, the quick release will not connect or work. The bolts that came with my Momo wheel and hub were of the perfect length.
Finally, connect the horn button to the wire. That’s it. You’re done.
Using the Quick Release
Line up the wheel and the hub...
Rotate the LOCK arm. Done!
It’s very easy to use. Just line up the wheel and rotate the appropriate arm. If you’re locking the wheel in place, the QRS makes a very nice *click!* once everything is rotated into position. To unlock, just rotate in the other direction. And it is actually harder to release than to attach. It likes to stay attached. I consider that a good thing.
The turn signal is still easy to hit.
I’ve been using a 10mm Momo spacer between my hub and steering wheel. Due to my Lotus Elise seats, I sit a little farther back from the wheel than I used to. A small spacer was needed. Now, with the QRS, I’m only adding about 15mm to my previous hub thickness. And really, that’s not much at all.
I have no problem hitting the turn signal with my thumb coiled around the steering wheel grip. The spacing between the wheel and signal is now just about equal to what Mazda gave their Mazda3 cars stock.
The quick release matches the hub nicely.
Daikei and Works Bell put exactly the same texture on these two parts. They look like they were meant to be installed together. I actually had no idea the match would be this exact when I ordered the QRS. It was a happy bonus.
With the wheel locked on, the little ears of the QRS hide behind my Prototipo’s spokes perfectly. It’s hard to tell the quick release is even there.
Total hub depth.
Works Bell QRS - one inch thin.
Hopefully these measurements help a few people. I’ve seen a handful of measurements of various hubs online. Too often the photographer measures everything including the steering wheel rim. That’s… not so helpful. Different wheels have different depths. But the distance from the base of the hub to the wheel mount is pretty constant.
Daikei hub + Works Bell QRS = ~4 inches thick.
Obligatory wheel-off shot.
Just as I said in the beginning – photo whoring. Hope you liked it.
