I was out doing some hill climbs today, and after the last one I was thinking that the hill felt a little harder than usual. After spending a few min. I noticed the wheel was not true (it was earlier lol) I rode a few miles back home after opening the break a little to allow for the slight wobble it had. I then inspected the wheel while getting the bike in the ar to bring in to have them trued again and I came across the damage in the picture. Its on both sides of the rim equal in length. I dropped the bike off at the shop to have the repair done. I asked him if we can get the hoop replaced through warranty, and he said he would try. Was this something I potentially did? or does this look like a defect? The only sort of bumpy thing I went over today was one of those smoother rail road crossings they have been putting in everywhere here. Barely felt it after going over. The rest of the ride was pretty smooth roads and climbs.
