So I just noticed a few minutes ago messing around in my driveway, that when I put a lot of weight on the rear of the bike, my tire would rub on the chain stay (I think it's called the chain stay anyway). I think I can just replace that part. Does anyone know for sure? And is it the chain stay? It's kind of frustrating. I have no idea when, where, how this could have happened. I've had it for just over a year. I haven't even touched pushing it to its limit. I know this bike should be able to handle a LOT. So I'm confused. Either way, there is this picture. And should I just look for a new chain stay?

not replaceable, but it's covered under warranty if you bought it new from a shop and have your receipt.

I'd contact Jamis (or the LBS where you bought it) to see if there is a warranty on it first. If not, look into having it welded up.

Wow, looks like Jamis has some problems with the chainstays. Toward the bottom of this link someone said it broke while just doing circles in his driveway. I was seriously doing that just now. Must have been this that broke it. It wasn't broken yesterday.

It totally looks replaceable so it's gotta be. If warranties last more than a year I might be alright, but I also bought it used so I think I'm screwed.
Will welding it up really work? Just seems weird. I know some welders.

AEO

is it suspension frame? I assumed it was a hardtail.

welding it back together is quite difficult, as it'll need to be TIG or MIG welded and the welder has to understand that it the tube warms up very fast and it needs to be heat treated after welding. But if the welder is competent and knows how to work with bike tubing, you're all set.

Welding thin aluminium parts and not producing troubles in the part is a bit of an art. Unless the welders you know typically do jobs that are this delicate I'd suggest you go for the replacement option.

As for the welding option seeming a bit wierd how do you think the frames are put together? Those beads of what looks like glue are welding fillets. So repairing this bit with a new weld would be very much in keeping with how the bike was built in the first place.

snaketheblake

Well yeah, I know it was welded, but it seems like it would be frail if welding over again for some reason. That's why I asked, because I don't know anything. I appreciate everyone's replies very much. I will ask my buddies who weld and see what they think. I don't know if they do stuff that delicate.

Also, I am waiting a reply from a friend who works at a shop to see if there is a way to still get the warranty even if I am not the original owner. If I CAN get it somehow, that's the way to go. If not, we can weld it and see what happens.

The suspension component should be reparable by un bolting the 2 ends of it,
one in the picture,

the other end where the front pivot is, and fitting a replacement part.

but if the warranty covers it, all the better.

snaketheblake

Yeah, it's replaceable. Don't know about reparable, unless welded, which I guess we'll probably find out.

It is not a hard tale as somebody mentioned, just wonder if you can put another rear end, the chainstays and seatstays are basically one piece that pivots in the bb and in the upper shock, one option is to ask jamis if they had one moving around, welding doubt will help since it is AL u have to put that thing back in the oven or it will snap again somewere else.

Another option, nail another frame and move your parts over? if the frame is too big or too smal just move the rear end of the bike?

Carbon fiber experiment fix? probably will hold even better than with the welding.

Jamis' warranty is for the original owner. Their warranty department is excellent, I can tell you if you had bought the bike new and your Jamis dealer emailed them a pic of your broken frame, you'd have a part coming your way that same day. Since you have a friend at a Jamis dealership, you may still get treated as if you bought the bike new. The warranty is not supposed to be valid for bikes bought used, however. I'm not trying to start a "warranty debate," (there was a noteworthy one in the road forum concerning a Trek bottom bracket shell) just giving you the facts.

So I've been looking online for just a chainstay for this bike. I cannot find one for the life of me, and I usually consider myself to be pretty savvy when it comes to online stuff like this. No idea what to do. Any ideas? I am awaiting a reply from Jamis to see if they can hook me up somehow. That might take a few days, I realize, but shouldn't there be stuff online?

What you need is a swingarm, which is essentially the rear triangle of the frame in this case. I would imagine Jamis would sell you one if you go through a Jamis dealer. When they replace one covered by warranty, they send the swingarm assembly complete with new pivot bearings, ready to be bolted onto the rest of the frame.

snaketheblake

Okay, I'll look for that then just in case the Jamis dealer here in town can't get me hooked up. He didn't seem like it would be a problem even with me being the second owner. He said they usually don't cause problems when he contacts them. Even if they won't get me one for free, he said it would probably only cost $50-60 anyway, so for me that's no big deal. I will get looking for swingarms. I don't need the whole triangle, but if they send me that, SWEET. Thanks for all the replies, guys, I appreciate it. My bike is in the shop right now, I took it in a couple hours ago. He said he would take pictures of it and send it to Jamis tomorrow. I sure hope he sends them digitally right away.

Good news! New swingarm on the way. A newer reinforced swingarm. No charge. Going to be shipped to our Jamis dealer and I will be very glad to pay the shop owner a fee for installing it. I'm so stoked!

LarDasse74

That is awesome! Next time, no riding circles in the driveway! I hear that is what makes most of these frames break. (joking)

snaketheblake

Well it's all taken care of. The new swingarm is supposed to be reinforced. Hopefully I can keep dinking around in my driveway while I watch my kids and that my burly bike doesn't break doing something stupid like this. I really love this bike so I am so happy they fixed this all for me.

Also, something funny was that before I ever contacted the local Jamis dealer, I sent Jamis and email making an inquiry about the whole deal. They only got back to me today and they told me it wouldn't be under warranty because I wasn't the original owner with the sale receipt. Little do they know that it's already fixed! Hahahahahahahahahahahahahahaha! My secret remains.
