How do you get the rear drop out adjustment screws to stay in place. The little spring keeps popping the bolt forward. It stays in place on one side but not the other.
Dont the threads in the dropout keep the bolt in place? The spring just gives the bolt a little tension.

I had trouble with this. My bike shop called quintant roo and they told them to glue it in place with lock tight. Not acceptable. I’m still having problems with it. I’m resigned to just not touching my rear wheel. I’m scared of it.
Sounds like (shudder…) you may have some stripped threads in there. That’s the only way I can think of that the bolt wouldn’t stay in place…
It’s a terrible design. The little bolts thread into some pretty pithy alumnium that is soft as peanut butter. The thing is sloppy. The bolts are some kind of harder material that just reams out the alumnium and wrecks the threading. Not a good arrangement.
For a manufactuer to tell customers that there $2000+ new bike has to have its rear wheel glued in place becasue the adjuster screws strip easily is the reason I’m staying away from carbon bikes with horizontal dropouts.
These desing are cobbled together. it is a contest to see who can make the coolest looking bike. Shame on you if you ever try to ride it.
I have to agree, as much as I love the bike this is a really poorly thought out way to do this. The bike is brand new, hasn’t even been ridden yet and the threads are already stripped. I will try the tape suggestion above and maybe I can come up with a better long term way of doing it. Why didn’t they just make the rear dropouts from steel I wonder? The weight difference wouldn’t have made THAT much of a difference, not nearly as much of a difference as having a wheel swing lopsided on you mid ride because the threads gave way.
Manufacturers need to learn to take a closer look at this *before *the bikes hit the consumer sales floor. There is a lot of wisdom to bike companies that test prototypes in the real world with a non-consumer test staff such as a cycling team first.
Cervelo’s experiences with CSC have yielded tangible results with product development so that by the time new equipment hits the sales floor it has been significantly de-bugged. Cannondale did the same with Saeco and Trek with Discovery.
In any case, it seems to me that sometimes certain bike companies don’t even assemble production bikes on an occasional basis and perform routine quality control.
I wish they were more careful.
I agree 100%. At the prices that bikes sell for, things as integral as this should be tested a bit better than they appear to be.
On a positive note, I took the screws all the way out and reversed them, putting the end cap/but on the inside. This spaced it out just right so the wheel tucks tight yet doesn’t rub. So at least I got it working for the time being. Maybe I’ll write a letter to QR, or well I guess ABG, asking if a replacement rear dropout could be created. If one was this would fix the only problem I’ve seen on the bike so far.
