Transition Issues Voluntary Recall of TR11 Alloy Frames

Jul 11, 2023 at 12:07
by Mike Kazimer  

Transition has announced a voluntary recall of certain TR11 Alloy models due to a heat treating issue on the chainstay yoke that could potentially cause frame failures. Transition will be shipping replacement chainstays to customers and dealers within the next few weeks. In the meantime, riders with the affected frames are instructed to not ride their bikes due to safety concerns. The full statement from Transition is below.

Statement from Transition Bikes regarding the TR11 chainstay recall:

bigquotesTransition Bikes has become aware of a potential safety issue on some TR11 Alloy models and has decided to issue a voluntary recall to ensure rider's safety. In some cases, the metal of the chainstay yoke may not have been heated sufficiently during welding, which can lead to poor weld penetration and premature failure. We have seen a limited number of failures and no injuries have been reported thus far. Unfortunately, there is no way to determine which units are affected by visual inspection. Due to this, we are initiating a voluntary recall of TR11 Alloy framesets and complete bikes with serial numbers TBC4801XXX, TBC4802XXX, and TBC4803XXX.

As riders ourselves, safety is our number one priority, we ask that anyone with one of these potentially affected frames/bikes stop riding it immediately. We are working to have replacement pieces built, tested, and sent out immediately. We will be shipping replacement chainstays to dealers and customers within the next few weeks. We understand that this is prime bike riding season, but please refrain from riding your TR11 if yours is in the affected serial number range. We will have you back on the trails in just a few weeks. If you have any questions, or concerns, please reach out to Transition Bikes via email at

Thank you!
Transition Bikes


USA and Canadian Customers:

If you have a local Transition Bike dealer, please reach out to them for assistance. The replacement chainstay will be shipped and installed at no cost to you. If you purchased the bike directly, do not have an authorized Transition dealer nearby, or would like to handle the replacement yourself, please follow THIS link, and we will get you taken care of right away.

International Customers:

If you live outside the USA or Canada, we would ask that you work with your local distributor or dealer from whom you purchased the bike to help handle getting the replacement for you. This will be the fastest solution for you. The replacement chainstay will be shipped and installed at no cost to you. Follow THIS link to find our distributor list.

 You have had great support in the past with warranty of frames. I appreciate your dedication to warranty and this recall.

 What a contrast to Rocky Mountain!! The clearcoat is peeling off my new Altitude frame at the headtube and the warranty has been disallowed. Apparently it was somehow caused by the Ridewrap even though the peeling emanated from the head tube and migrated towards the Ridewrap and the spreading has actually been stopped by the RideWrap.

 Seems like a lot of bikes break nowadays but when I warrantied my tr11 a few months ago it only took 2 days for them to get me a new one (granted I live in Bellingham). Regardless of the warranty issues they are always diligent about righting their wrongs and that’s why my next bike will be a tr as well.

 I just had a chainstay break at speed in a berm at that very same weld spot on a different kind of bike, it's quite exhilarating and everyone should try it from time to time.

 @rickybobby19: I've cracked more than one chainstay right at that spot too, on the drive side.

The compression from pedaling, then the extension from hitting things puts lots of stress on the aluminum right there.

 @stuie321: Rocky Mountain sound like they provide a similar type of warranty to Orbea... ie non-existent.

 @LiveFreeorDie: I found a very faint crack in my Levo’s headtube while I was regreasing it. I took a couple of pictures, sent them to Rider Care and my LBS and they warrantied the frame no questions asked. They swapped the entire bike since that was cheaper than moving everything to a new frame.

 @Ttimer: Transition maybe has the best warranty service in the industry. I know people who have bought 2nd bikes called them up and got helped out. When I had a warranty it was basically no questions asked. And they got me the frame within 2 weeks and just asked I sent the old one back AFTER I swapped the parts over.

They’ll do right.
  • 3 0
 @Ttimer: They have the best warranty in the business in all my experience. I cracked my TR11 frame, went on the Transition website to view my order, clicked the warranty button, uploaded a picture with a short description and I had a response and a shipping confirmation the same day. My replacement frame showed up in 3 days and I didn't miss a day on the bike. They stand behind their products and couldn't have made it any easier for a customer. There's no doubt they'll make good on this.
  • 3 0
 @bulletbassman: depending on the scale of the problem the reality of the situation is that Transition's frames are manufactured abroad like most others and some things are outside their control. I don't doubt their good intentions and I am not suggesting they don't perform above the industry average when it comes to warranty. But ultimately if it's not your on site team doing the welding it takes more than wanting to do the right thing and trying hard. Hopefully they already have a shipment of TR11s on the boat they can strip the rear triangles off of and send to customers while production catches up.

 Interesting there’s a theme of this sentiment here when the only reason they’re doing this is because they’ll be sued into oblivion if they don’t remedy the issue and the chain stay fails on someone. They’d be found negligent in court in a heartbeat.

People are failing to see the difference between a legitimate safety issue and user-caused failures or cosmetic issues.

 Any transition owners having issues with the suspension linkages breaking? My buddies carbon Scout is on his third (!) warranty claim in the last 90 days because of the carbon delaminating around the suspension bearings causing them to come out. Transition and Rose bike in Orono ME have been great about it, but this is insane to me. The poor guys spent more time driving to and from the bike shop than he has actually riding it.

 Does your homie have a real torque wrench? Sounds like he's overtorquing the pivot bolts to ape spec.
  • 11 6
 Raced on a devo team supported by transition for a few years (2019-2020). Between about 15 riders, ive never seen so many bikes blow up. Carbon around bearings wallows out, multiple shock bolts snapping, lots of downtubes cracked from rocks popping up, and my bb housing fell out once because there wasn't enough glue. At least it was easy to glue it back lol. Great bikes but they are made of glass.
  • 2 0
 @stravaismyracecourse: bikes got less than 100 miles on it. He had no reason to even touch the pivots at all in the first place. All warranty reassembly was done via the lbs where it was purchased. something is clearly out of alignment or flexing more than it should and causing load where there shouldn't be.
  • 2 0
 @stravaismyracecourse: or the bearing and or bore are not to spec, or the backup support for the bearing isnt in spec so the link is flexing when tightened down.

 @bulletbassman: that's what the LBS is supposed to do. I'm gonna take a guess and say that 95% of people who purchase MTBs do not even own a torque wrench, let alone checking the torque specs on a new purchase. Very naive comment.

 @rclugnut: Many possibilities, but when problem solving, usually best to start with the easiest/most likely. Assembly error is way more likely than consistent production issues, especially if it has been assembled by the same shop every time.
  • 1 0
 @bulletbassman: my first ride was 1 mile into the trail sadly. I absolutely believe there is something badly aligned in the rear, because after the last bearing blowing out the side I went and hit the biggest jumps as fast and hard as I could, (was at MT Abram on big bermed downhill) and nothing creaked or broke any worse. I was fully intending to bring that bike back in pieces because this many problems in less than 70 miles is annoying. The fact the bearing was halfway out of its resting place and taking major hits tells me they have the geometry and spacing wrong from the factory.

 @bulletbassman: Ill follow up to my comment since I cant edit it; hitting a jump as hard and fast as I could wasnt really anything all that impressive. tabletop type jumps with less than 3-4 feet of vertical air, no big drops. Ive gotten old and worry more about breaking myself!

 @MartyMcfly2810: interesting....I have cracked my first Spire alu raw front triangle got a replacement one (only front triangle - but fast). But soon I found out that rear shock mounts are misaligned -> so another warranty case. That one took a while since they didn't have raw frames in stock....first they offered me orange triangle but was not acceptable for me with raw rear end. They refused to get me a whole frame or carbon one....only way was to wait a few months....waiting was prolonged two times....but then after some talk they finally found/received Raw frameset for me (4 months of total waiting time - not happy with procedure of second warranty case). This one (3rd frame) is now aligned and still without cracks - will see how long it will hold.
*also seatstays cracks on Spire at brake mount
I am surprised how so heavy frame (4kg without shock in size XL) couldn't withstand one full season.

 Good on them for warranty. That is how everyone should do it.
Try getting a Small Raspberry Red Scout Frame in the UK though! , I first pre ordered one in Nov 2022 after being told would probably arrive with distributor end of Jan 23 and lbs shop said April ... I waited ....April came along lbs didn't have any, they didn't get much info from Transition either, I emailed distributor in UK..and was told, expecting them towards the end of year at earliest. Unfortunately had to cancel my order. I'm patient but wasn't going to wait a year, maybe more for a frame. I get they are popular but to keep pushing/advertising pre orders with such long/vague lead times is not the best

 I’d never hesitate to buy a transition. They took care of me when they didn’t need to. Bought a used alloy Spire, realized about 4 months later that the lower shock mount was welded about 3mm out of spec causing premature wear on the shock. They could have told me to kick rocks since I bought used. They instead sent me a new front triangle. They are stand up people and do what they can to keep you as a customer.

 Props to @TransitionBikeCompany for taking a proactive approach. I've had nothing but great customer service experiences with the folks at Transition. They have always been fast to respond, beyond fair in what they have replaced (at zero cost to me), and always did everything they could to expedite shipping to NH so I'm not left without a bike. Not to mention a free hat and t-shirt along the way! Cheers Transition and a special thank you to Dillon T & Ryan F. for your help with my claims. You guys were both great to work with.

 No doubt that TR have a good actitude and policy in many bike areas but they have done a huge bad choice essentially to a ebike owner and it was to choose a shimano motor that dont assist their motor outside warranty time ,2 years.This is the oposite of TR pollicy for treat well and loyalty to their clients.I They are not 300$€£ bikes made to last two yeras ,indeed 300$ bikes lasts twenty years.Its because of that i didnt bought a repeater .Fazua its no also a a good choice in the Relay with 430w battery for enduro bikes.Its only the opinion of a water drop.
