Faulty seams on Kinlin rims?

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them.

Faulty seams on Kinlin rims?

I had some nice wheels made by Rob at Psimet -- he used Kinlin 270 rims. The other day my rear brake was catching on something on every revolution. When we examined my wheel, the seam on the rim was raised a little bit. I have sanded it down with steel wool, but I'm worried now that I see how prominent the seam is on both rear and front rims.
Has anyone else had issues with Kinlin rims? I thought they were supposed to be high quality rims. I sent a picture to Rob at Psimet but have heard nothing back. I'm wondering if I should get different rims and have my LBS rebuild my wheels.

I have a Kinlin rim on my rear wheel. It's seams are fine. Kinlin rims have a good reputation for a reason -- they are good.

If there is something wrong with your wheel, I'm sure Rob will take care of it.

I had this same problem with one of Neuvation AERO3s when I got them, John at Neuvation sent me a replacement before I could return the defective one,he also sent a prepaid shipping lable, I guess this kind of thing just happens now and then.

The seam is noticeable on mine, but only from looking at it, not from any performance aspect. It's a pinned rim instead of a welded one, which is why there is the more visible seam. If you look at most factory wheels, they just cover the seam up with a sticker so you don't notice. Plus, the seam gets worn down by the brake pads over time, and becomes less noticeable.

I would imagine the fact that you sanded your rim down with steel wool would preclude you from any sort of warranty type service, unless he was feeling mighty generous.

Kinlin rims occasionally have issues with the joint. It is rare, so it is easiest to get a replacement rim and rebuild the wheel using the same spokes.

I've had brake pulse on XR200 rims. At first I thought it was the seam but now I'm sure it's something else. The brake track width varied slightly, thus the "catching". There is no solution. Fortunately at higher speeds it's not a problem (only from 10mph to 0 do I feel it).

I still swear by Kinlin rims for their cost/weight/strength and I build them up for friends without thinking twice.

could you take a picture & show us what you mean by the faulty seams?

thanks

Same thing with my XR-270 front and XR-300 rear rims. It is bothersome for sure, but as you say it's only an issue when going slow. If these rims ever need replacement, I'll likely try something else.

Wow, I use several Deep V's on my bikes but often hear of others dissing their QC. I myself have never had a problem but thought about experimenting with the Kinlins after several posts praising their superior quality to Velocity.

After reading a post where PeterW praises Velocity, I think I'll pass on the Kinkins. Plus Velocity offers a variety of colors.

I do believe the braking surface on Velocity rims are superior to Kinlins. But really, it's not a big deal either way. They both make nice rims.

Here's a picture of the seam. (Click on it to enlarge it). I would have thought nothing of it if it hadn't started making the braking noise...I've been looking at all kinds of wheels. My Mavic Ksyrium SLs conveniently have a sticker where the seam is...

The seam is normal. Mine have them too. It's not worth replacing the rims unless the seam is actually loose (spoke tension will hold it tight unless there is a serious problem with the rim). There's not usually a noticeable seam on the brake track but if there is, sand it down with some emery paper on a sanding block. You want to sand the edge off but not sand a depression into the rim, which is what will happen if you hold the sandpaper in your hand.

Don't use steel wool on aluminum rims. You will embed small steel particles in the aluminum and they will rust.

I have had to knock off an edge on the brake track of a number of rims. It's not a big deal.

If Neuvation uses Kinlin rims, my Kinlin rims are holding up nicely. My rear lasted five or six thousand miles before I started getting continual spoke and nipple failures, so I sold that off to a friend who's going to rebuild it. My front wheel has got to be pusing eight thousand miles and the only issues I've had with it are first, it recently started making a faint "click" sound when the rim joint gets closes to the ground and second, there's now a small but visible gap at the joint in the black part of the rim. The braking surface is still perfect, though.

And I started on those wheels at over 230 or 240 pounds - currently about 210.

Thanks, ericm. My local bike shop mechanic agrees with you. Actually, I did use some steel wool, so I'll inspect it closely and use the emery paper w/ sanding block if I need to do anything more.

Interesting. I haven't seen enough Kinlin rims to know whether it falls within the range of normal, though it sounds like your mechanic and ericm think it is normal, but the seam in your picture is much more pronounced than the one my 300 (which is very hard to even find).

Resolved

Well, I haven't replaced the tire yet (lazy: want to clean the cogs first), but the consensus is that the seams are good. Rob at Psimet looked at my picture and assured me it was normal. So: I'll clean the cogs, make sure the brakes are set properly and that there's nothing in the pads, and put everything back together and hope for the best. Thanks everyone for your input. Learned something. By the way: Rob (Psimet) has a reputation for building really nice wheels. I was considering some $1000 wheelsets for my new Moots last year, and Rob built me these for a little over $600: Kinlin rims, Sapim spokes, and White Industries hubs. Very nice.

I have Kinlin 200s and the seam is no where near that prominent.
