So last week I t-boned a car running a stop sign with my 3 week old Trek 4300 Disc.

I took it in to get repaired so I could sell it to a friend, but the shop and I had some miscommunication errors when I purchased a GF Piranha and they weren't very happy at all. So i'm wondering if this is normal for a Trek 4300, as I don't remember it being like this before.

Basically it looks like the Crank bearing is exposed to any dirt/sand or water that gets up in there.. and that just does not seem right to me. Anyone here with a trek 4300.. is that normal?

Here are some pics:

Here's what it looks like on my Gary Fisher:



p.s here's the aftermath of the t-bone.

It looks just like my 7 year old Trek 4500 did. About 2 weeks after I bought it I was doing some riding in sand, when I noticed a grinding sound in the BB. The wrench found sand in the BB bearings and replaced the BB with a sealed one under warranty. I have had no problems since.
