Isaac's Shifting Lever

I took these pictures the other day, I didn't get them as good as I wanted but I was using a camera phone. I was inspired by JRuss to show these pictures because he has some similar photos from his un-motorbike. He broke a crank with those powerful commuter legs. If you have the time check out his technical discussion about aluminum failure.

So, this is the gear selector lever that Isaac broke when we were riding on the Hatfield and McCoy Trail last weekend.

I did see the small cracks when it fell off earlier in the ride. I knew it wasn't going to last. But, when your on the trail you have to make due. I have already ordered another one for him. I hope it gets here soon, we need to ride again.

Even though this picture is blurry you can see the light and dark area in the fracture that JRuss is talking about.

    Nice. Well, not nice that it broke, but nice to see the failure mode. That particular piece looks cast, rather than forged, which probably didn't help the situation. Tell Isaac to quit being so hard on equipment.
