Rotor up

ACCESSORY 42: 160mm Avid G2 Rotors (3) $41.98 shipped @ Ebay

I can't believe these things normally sell for $35/each! Ebay's the best. The rotors came in! Though all the rotors are identical, they must be orientated correctly. They are directional. An arrow on the face of one side indicates the direction they're designed to spin in the forward rotation.

New vs. old. The stock Tektro rotor on the left was warped and I had been dealing with it by making brake adjustments to compensate. Once it started to rust though, it was time to swap them out for a new set.

This is the left front wheel. The original set required a T25 torx head to remove. The bolts were pretty worn out and at first it made me think they were hex screws.

The new set came with hex screws - size 3. They came with locktite already on them! How convenient! Again, the rotors are directional. After confirming that the rotors are in the correct orientation, all screws were secured.

Removing the front rotors also requires removing the wheel, but it's a bit more complicated to take off the frame than the back. An allen wrench is needed to hold the axle in place while the bolts are removed. The axle needs to slip out before removing the wheel. It took me about 20 minutes to figure out, but I'm sure I can do it next time in 5 minutes. I've learned that replacing it with traditional bicycle skewers is not possible due to the thickness of the axle.

Removing the front wheel isn't much of a chore, but it is more difficult than removing the back wheel. It requires a 17mm wrench and an allen wrench. I don't recall the size, but it's the third one missing from this red pack.

The axle looks like this. The right side has fatter threads and is orientated on the outside. After degreasing all the gunk, I put some new grease on it to keep it running smooth. I used locktite on the threads when replacing the nuts and washers.

I was in a bit of a hurry for dinner so I didn't clean the wheel, but this would be a good time to do it while it's off the trike. It's much easier to get into the grooves to clean it out from sand and dust that's collected. Brake adjustment is next.
