While changing my front tire last week the night before going up to the fall color tour here in northern Mi. I noticed that my rim was cracked completely across and with almost complete penetration. What a bummer , I took the wheel off of the bike and took the rim and had a friend weld it to get me through the weekend. He did a tig reverse ac weld and it looked terrible but it held up and got me through the ride a little out of round, but considering the alternative- not riding I was happy with it. Has anyone else had this happen? this was a DID rim. So it looks as if Im going to get an excel 21in over the winter for the front.
