I cant be certain but that looks bad and the warranty should cover it.Just noticed this crack or scratch on both sides of the front rim of my bike. Less than a year old with only 450 miles on the clock. I've contacted the retailer to ask if this needs attention or is just cosmetic. What do you think?View attachment 145668View attachment 145668View attachment 145669
Yes it's the rim seam, directly opposite the valve. I can feel the seam of the rear wheel by running my finger over the same spot, opposite the valve. But the rear seam is not visible like the front one. Never seen anything like this before.that looks morel like the seam of the rim. it would be easy to check if you take the tire off and its on the inside. cranks in rims usually are around the spoke holes going around the rim.
It might just be a blemish. Take it to a shop and left them check it out. You do not want a failing rim!Yes it's the rim seam, directly opposite the valve.

It can get dirt in it. Some are harder to see then othersYes it's the rim seam, directly opposite the valve. I can feel the seam of the rear wheel by running my finger over the same spot, opposite the valve. But the rear seam is not visible like the front one. Never seen anything like this before.

I have seem some lectric rims with a gap there. that was normal for themThat is just the seam where the two ends of the rim extrusion are pinned together. Aluminum rims are pinned, welded or inserted sleeve. It's not unusual to see the splice especially when we used to use rim brakes. There would frequently be a smear from the brake pad at the joint. It is always 180 from the valve hole and centered between two spoke holes. It may not always be visible depending on the rim finish and I've got at least one rim where they put a label directly over the joint to help hide it.
Edited to add: Asking the shop will be best for your peace of mind.
Nothing to keep an eye on. As others have already said, that seam is perfectly normal.I was going to reply but forgot what the thread was about. Closer to xx and yy!
But I'd also keep an eye, a good one if there is such an eye, on it for a bit.
It means you need to spend more time riding and less time looking at your bike.I've heard back from the retailer;
" Basically, when the rim is made it is just one long piece of metal rolled up to form the rim. It is then joined together with 2 interference fit pins on the inside (which you cannot see) On the more expensive rims this joint is then welded and smoothed down to show no join.
The rim is perfectly safe to ride and will not cause you any issues."
I was just thinking how weird, after nearly 60 years of racing, touring, and endurance events, I've never come across this before. Then I thought, hmm, I'm sure I had............but my memory...........er...........what was I saying?
Fortunately, I did look at my bike two weeks ago. We were riding and went through or near a patch of broken bottle. I decided to check my tires. When I did so, I noticed a never before seen feature in my RIM. A "drain hole!" Actually, it was a disconnected spoke. Apparently, the nipple unscrewed and my spoke detached. There was no obvious evidence. Brakes did not rub and my friend following behind said she did not notice any wobble. Fortunately, the unscrewed bit did not manage to cause a flat tire, floating around inside the rim. Six miles home and then into the shop. But as luck or irony would dictate. Repaired bike on my next ride got a FLAT!!! Unrelated to the day's earlier spoke incident. Oh, well, ain't bike riding fun - SOMETIMES!It means you need to spend more time riding and less time looking at your bike.
