2nd bottle cage, problem bolts

by bikeboy76   July 27, 2013  

I have had my current bike for nearly four years. I have had a bottle cage on the diagonal for all that time. But recently the cheap wire cage just became too rattly on the bad roads to tolerate. So I bought a nice pair of Lezyne Flow cages. My idea was to get a second cage on the vertical tube and use for a second bottle on long rides or a storage bottle for my phone/keys/tools if I want to go for a quick blast in a skinsuit with no pockets.
The bolts for the second cage has merrily sat there forever but when I tried to fit the new cage they just would not hold in and the cage fell off. I tried swapping with the bolts on the other cage but with the same effect. It seem like the internal bolt housing. They will screw in but won't hold the cage when I try to attach it. They are allen key bolts. Anyone know how I could make them work or find a cheap alternative bolt, I don't imagine BnQ would have something so specific?

Ok, maybe I've missed something but is the 'plate' bit of the new cages thicker than the old cage. In other words are the bolts too short?

Some cages (Spesh for eg) come with new bolts.

Either the bolts are too small (they may be M4 bolts trying to fit in an M5 hole), it's also possible that you may have stripped the threads on the bolt bosses. Check the size of your bolts first, M4 and M5 are most likely bolt sizes.

The plastic on the new cage is thicker than the original metal cage I had. I never used the down tube bolts before but the same bolts work fine in the same type of cage on the diagonal front tube. There were some screws that came with the cages but just to attach it to the card, they just rattle in the frame holes and are not the right size at all.

I am stronger than Mensa, Miller and Mailer, I spat out Plath and Pinter.

It does sound like the bolts are too short to me, purely by what you describe. I take it the old cage still holds, right?
If so, some longer bolts from a lbs should sort it.

If all else fails, there's always Loctite threadlock...
