PSA- I want to give everyone a heads up if you're riding a Quintana Roo. I've owned and loved 3 QR's over the years! My third and current one is a a PR Six. I was on the front of a ride and as I went to drop back my back wheel locked up, made me skid and I almost went over the bars as I was at 30mph+. Long story short, the screws hidden inside the storage box (not the lid) which attaches to the frame came loose and caused the storage box to sag down on my wheel causing a rubbing-lock up brake effect on my tire. If you own one of the PR's then you know the back wheel and storage box have a very tight clearance. I had to have storage box taken off just to be able to ride home (tire trashed). After this- I will NEVER put the unit back on. I'm thankful I didn't take an entire group down with me as I got the bike semi under control until I came to an abrupt stop in the grass. I contacted QR on 6/1/21- the date of incident, did a f/u and they were going to get back to me. I have yet to hear anything yet (allegedly looking into) on this storage box which I see as a potential catastrophic problem for many. My bike is constantly maintained at my local bike shop and nothing felt loose prior nor would it ever occur to me that inside this unit there are tiny screws that may come loose or detach from the bike frame. The design is for sure missing something and I hope it gets corrected. Check yours asap and continue to! PS. I know the Slowtwitch- QR connection so I was hesitant to post but I'd rather everybody be warned and be safe.

Sorry to hear that. Do you routinely tighten all of the bolts on your bike? I typically check all of the vital bolts before each ride, and all the others every couple of rides
Bolts inevitably come loose from the vibrations of bike riding. Certainly not a manufacturer mistake. It is necessary to always check them to make sure things like this do not happen

Agreed. This is a maintenance item. Drop any part against the tire and it can wedge in there. I can’t think of a bolt on a bike I haven’t seen come lose at least once over time.
Re: Quintana Roo warning [iamuwere]
[ In reply to ]
I can. Yes I regularly wash and inspect my bike but things aren’t just dropping off all the time.
Loctite might have helped but ultimately my bottle cages aren’t regularly coming loose or my top tube mounted bento.
I’ll await some pics/diagrams before I just condemn the OP to not using enough Loctite.

There are bolts that don't ever really come loose, as you said the bottle cages are one, but I routinely find bolts in my stem and headset that come slightly loose. I'm not surprised that the storage box in that location would come loose over time
Any bolt that could cause catastrophic failure I check quickly before each ride. The other bolts I just give a twist to every few rides, like the brake lines and derailleurs. Simple enough maintenance and a good habit to get into

Re: Quintana Roo warning [RossJ]

If those bolts keep coming loose, you're using either not enough torque or low quality components. I never have to tighten a single screw on all my bikes, unless I make a plain build mistake. What happened to the OP is either installation or design issue; nothing to do with maintenance
Re: Quintana Roo warning [KSP]

Thanks for the warning!
My wife has a demo-model PR5 and the box came attached with tape only because the box where the bolts attach had bolt sized holes. I was still thinking of re-attaching it but will now leave it box-less.
Note: my Speed concept box is rock solid and does not need any servicing.

Yeah sorry to pile on, but this has absolutely zero to do with QR, and everything to do with you not checking your bike and/or someone not having properly tightened the bolts in the first place.
I don't even use loctite on my bike threads, I've always used bronze anti-seize on all threads, and nothing has ever come loose as long as the are tightened properly.
Glad you are OK.

Re: Quintana Roo warning [JerseyBigfoot]

Bolts are inside this box. If you watch the video online by QR it shows they are on with an automobile adhesive not screws. Mine did not Repeatedly loosen or come off. This was a first time and I had no idea the bolts were inside that box. When I asked around numerous people told me they had a problem also.
Re:

Not a QR problem. Bolts got loose onBTA bottle cage and I had to do entire race listening to this rattle noise. Since then, I check every single bolt once in a while. Loctite is definitely a good option. Blue loctite should do the work.
Re: Quintana Roo warning [KSP]

My Felt IA draft box bolts loosened once. Now I know to regularly check and tighten them, like all the bolts on my bike. (My road bike bottle cage bolts frequently loosen as well.)
Re: [s13tx]

Wouldn't a water bottle cage be an added feature? My box is an integrated feature on this bike. I do check all and tighten inc.. arm pads etc.... If this comes loose on a 120 mile ride you are screwed. Loctite Is a great tip though not sure if somebody was seriously injured that a court would say Loctite versus product liability. I will post a picture when I figure out how to put one online. I don't have a product Engineering design background but I do wonder if a lip underneath the cage Built into the bike would prevent it from rubbing on the tire causing a lock up. My goal in posting is to warn and prevent anybody from getting hurt.

Just like any part on your bike, integrated or not, its still your responsibility to make sure it is installed properly and tightened properly.
Re: [KSP]
[ In reply to ]
although i do genuinely feel bad that happened to you and hope you're ok, i'm also of the position that it isn't a QR problem unless you torqued them up yourself before that ride and they STILL came loose.

I'm going to be "that guy" and ask.........have you got Di2 on the brakes on that PR Six for doing group rides like that? So that you can sit up and participate? There have been some "yard sale" level crashes at a local group ride that mixes folks on mech shifting tri bikes with road bikes all in a pack.
That's a whole bunch of "hell no" to me.
I ride my TT bike like 75% of the time on road rides, alone. I'm a roadie, not a triathlete. I take the roadie to group rides. I've won TT races. So I "get it", but I'd rather not pile up my TT superbike in a group fueled by testosterone and inflated egos and dreams. We've got guys on group rides that bring out cheapo used roadies or cross bikes and do fine.
Seriously not trying to be a D, just saying to stay safe out there. Make good choices.

Re: Quintana Roo warning [KSP]

First and foremost, I'm glad you and the group are all OK.
did the mounting bolts back out completely? I have a PRFive with the same box. It is mounted by a bracket that has to M4 bolts like a bottle cage. This bracket has a lip that is designed to sit on top of the seat stays that doesnt allow the bracket to slide down into the wheel. The box then slides into the bracket and has its own lip that also interfaces with the seat stays.
The bolts holding this on would have to be backed out essentially all the way.
Here's a couple photos for those who aren't familiar with the design:

You have to be careful using anti-seize, it basically halves the torque requirement on bolts, even blue loctite in theory reduces the torque requirement.
I add blue loctite, grease or assembly paste to nearly every connection on a bike.

In that case, have fun and carry on! Around here it's a mess of what I would say are often relative noobs or novices at tri bikes.
Thanks for sharing that to the group. On a similar note, if anyone owns the newer Trinity with the front hydration......my kit didn't ship with new screws for the face bolts on the head tube. I assumed and reused one and it was too short. Thing fell off mid ride similar to this but didn't hurt or bind anything up. So, use longer bolts if you have the Trinity front hydration system if it didn't ship with the right bolts.

The QR tent were nice enough to reattach the box when it came off at nationals in Cleveland when the bike tipped over before check in. They explained this was a weak point and the tape was much better to hold the box and that it would be included in the future.

What happened to the OP is either installation or design issue; nothing to do with maintenanceThe very fact that a totally foreseeable problem (loose attachment bolts ,- hidden ones at that) can result in wheel lock up and crash, tells me it's a design flaw. There needs to be a stop or limiter to prevent it fouling the wheel when it comes partly loose.
Checking for loose bolts is not the right solution to this problem.
If folks have to be checking bolts every other ride, either the design of the bolted joint is shiiite, or it was assembled by a monkey.
