FYI - Biketiresdirect.com has what seems like a pretty good deal right now on a dynamo wheel. For $250 you can get a DT-Swiss TK540 rim laced to a Shutter Precision PV8 front hub, DT Swiss Competition spokes, plus an iLumenox Vega 6V LED light. You also can buy the matching rear wheel -- sans generator hub -- for $140. Prices include free shipping.

If I commuted on just one bike, I would jump on it. However, I frequently ride different bikes on my commute, so a rechargeable LED light works out better for me.

My wife would kill me if I purchased another light but I'd love to get a dyno hub and light set (front and rear). My commuter is a touring bike so it would work for both roles.

There's no picture of the headlight.

For those who are not sick of my blog post, I have a very nice system that cost me about $160 to build. I build my own wheels, which saved me some money. You can get a front wheel with a Sanyo hub for only $100 nowadays! That's an unbeatable deal.

My dynamo system

No system is perfect, and it's true that it's not easy to move dynamo lights from one bike to another. I have a battery powered headlight that I put on the bikes that don't have dynamo systems, but I usually ride the dynamo-lit bike. It's the most convenient thing, because (1) I don't have to think about batteries, and (2) I don't have to mount or dismount the lights.

......and its much harder for others to "dismount" them for you.

Quite right. Someone tried to steal my light and failed. He bent the mount, but that was fine. I was able to bend it back into shape.

One day I'll set a bike up with a dyno hub.

No photo of light? Only 32 spokes?

Hey [MENTION=152773]noglider[/MENTION], how can I tell if a dyno hub is suitable for a disc-brake wheel?

I don't know, but I'm sure a search like this will do the trick. The Sanyo is not ready for a disc brake.

Bike Tires Direct has a disc-compatible version of the wheel on sale for the same price.

I've had this $100 dyno wheel saved in my Amazon wish list for a while: Amazon.com : Taylor Wheels 28-inch front wheel ZAC2000 with DH-3N20 - silver : Sports & Outdoors. Someone on this forum recommended (sorry I can't remember who it was).

A dyno for a disk brake wheel will have a mount for a brake rotor?....

Understood but both of these are for disc brakes yet only the left one has the recognizable six bolt attachment for the rotor.

And when you pop the rubber cover off the left side of the Alfine hub, voila! Centerlock rotor mount.



There are two "standards"--ISO six-bolt and Shimano Centerlock. Centerlock rotors mount with a lock ring identical to Shimano cassettes, and it uses the same cassette tool.

Hah! I didn't know that, I'll have to check my bike to see which one it uses.

If you're replacing the hub, it doesn't matter what you've got now. You just get a rotor of the right size and mounting style for the new hub. Of course, getting what you already have means you can reuse the rotor. There are adaptors to fit a six bolt rotor (generally a bit cheaper, and easier to find) to a centerlock hub.
