Mavic

I’ve had a set of Mavic Aksiums for a long time knocking around in the garage for ages. I’d not really used them in a long time, but decided to get them ready with a service and a couple of rides, as they make great winter wheels.

So, service time it is. Mavic freehub designs are a little different to the Fulcrum wheels I normally use. The drive ring is internal to the freehub shell, with the pawls on the drive shaft. I started by removing the drive end cap, and pulled off the freehub. Mavic hubs are known for the “Death Squeal”. Caused by the large plastic washer that presses against the hub shell.

You have to be really careful pulling the freehub off, the pawls and their springs may fall, they are not secure in their mounts. Take them out and put them to the side.

So, after the freehub is off, clean both interfaces of this washer, and check for wear. May as well check the bearings while your at it to make sure they spin freely. Clean all other parts. Don’t use degreaser near the bearings, just wipe everything clean. Mavic use a very light oil in their hubs, making it easy to clean up.

There’s many, many threads on what oil to use when lubing Mavic hubs. Of course you can use the stupid expensive Mavic oil, others say use gear oil, sewing machine oil, mineral oil and all manor of other oils.

I used bog standard chain lube. The finish line wet lube. It’s just liquid enough, but clinging oil. A drop on each pivot point of the pawls, smeared on the nylon washer. Putting the pawls back in, the small springs must be on the tiny post on the pawl. Rest the end of the pawl in its cutout, and make sure the other end of the spring goes into the depression on the hub.

To get the freehub back on, hold the pawls in, while lowering the freehub over them. Gently rotate the hub to make sure everything is seated. Re attach the cap, and done.

The Finishline lube I used has the added advantage of making this hub virtually silent. That’s something I haven’t experienced in a long time.

While being a cheap set of wheels, they are not a bad set of wheels, and are great for a set of winter wheels, commuter or just budget wheels.

Wheels.. They go round.

Well, mostly they do. I use a set of Fulcrum Quattro, they are now a few years old but plenty of life left in them. But they did need a bit of TLC the other day. I couldn’t be bothered to change the bearings so I swapped them over temporarily for a set of Mavic Aksiums that I have hanging around the garage.

The Aksiums, are in all honesty, a cheap set of wheels and it shows in their performance. They are heavy and slow. The other thing I’d noticed, was their breaking distance is longer than the Quattro.

On the second ride with the magics, my average speed was much lower, and I had a lot more effort going into maintaining speed. Then the noise started. The constant eek eek noise from the free hub. Drove me insane.

So they have been removed, and the free hub bearings replaced in the Quattro, cycling nirvana restored.

Another stupid maintenance story.

The bearings have gone in my fulcrum quattro, not unusual as Fulcrum ship with bearings that are sealed on one side only. So they do tend to go quite quick.

But I couldn’t be bothered to change them out yet. So I grabbed a spare set of wheels, a Mavic Aksium pair. Cassette and tyres mounted, on the bike and spinning. They are certainly not the best wheels in the world, but they work.

Off I went for a ride. Noise. Rubbing noise. Any noise on a bike annoys me. I checked the tyre clearances, break pads. All fine. Noise was still there. I adjusted the pads on the front wheel, I could swear the noise was coming from the front wheel. Checked spokes, all appeared to be tight enough with a simple squeeze test.

No idea what this noise was. Then, all of a sudden it disappeared, nothing, no noise apart from the road noise.

Shifted up into the large chain ring, and there it was again. I thought the cable may of come slightly loose as I hadn’t adjusted it since changing the cables, so turned the barrel adjuster a turn, span the cranks and the noise was worse. What the hell.

On look, the cable end was rubbing on the wheel…
