help - bottle cage mount in Ti frame damaged

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

help - bottle cage mount in Ti frame damaged

Basically, it spins in place but doesn't fall out. I think it was over-torqued when the cage was mounted. I think the mount is AL but the frame is Ti - when something gives, its the Ti.

Frame looks okay, but is there any good way to fix mount in place (like some sort of metal glue)?

I am so depressed right now, I think my entire weekend is shot.

JB weld is a 2 part epoxy that works on metal available at your local parts store and large Home Depot style hardware stores. Without seeing it I couldn't tell you if it would work or not. While your at the hardware store pick-up a couple some small nylon bolts for it (take a cage bolt with you to match the closest you can get, it will be ever so slightly larger), i use them on a couple of my bikes and they work great and weight almost nothing. The tops are slotted for a screwdriver and don't take much pressure to tighten them down.

didn't you mention you're in contact with Tom Kellogg? Give him a call--he's probably seen this before.

good luck

I'm guessing that you have a rivnut that has come loose. The way these things work is that when installed the outer part is held fixed and the inner part is tightened causing the cylindrical part in contact with the frame to expand and it is held in place by friction. Sometimes they can be retightened (a very quick job) but sometimes they have to be replaced (a tedious job if you want to be extremely careful to leave no grinding marks on your frames when grinding the head off.)

Do a search in the mechanics forum. I think that I've seen rivnuts discussed over there.

I can't recall for sure, but it seems like I've seen a tool for these before. My guess is if you have a good frame builder anywhere close they might be able to take care of it.

Good Luck - John

The basic concept for a homemade rivnut tool can be found here:

Adapt to your own situation.

Find a Lightspeed dealer...

Lightspeeds use rivnuts and this is more common than you think. Any Lightspeed shop worth thier salt has the tools to fix the problem locally. Goodluck.

This happened to one of my bottle mounts, I put a dab of Super Glue (cyanoacrylate), and it's been solid since.


Another solution would be to get a longer bolt (~2 in) and a nut. Thread the nut on to the bolt, almost to the head. Thread the bolt in to the bottle boss (riv-nut), at least enough to get the bolt pass the riv-nut inside the tube. Then thread the nut down on to the riv-nut. Use a 4mm Allen key to hold the bolt stationary, while turning the nut down on the riv-nut. This will compress the riv-nut and tighten it up to the tube again. Don't use a lot of force, just enough to coax it back into place.

Be careful to not turn the bolt, rather turn the nut on the bolt instead.

Thanks - I took it to the Capitol Hill Bikes in DC (where I bought it) and they reset the rivnut. CHB has been my favorite LBS in DC for a while now even though it's not that close to where I live. Depression has passed.

In celebration, and in light of the now bearable 82 degree temps in DC, I went and did intervals at Hains Point. Sweet bike or not, I'm still not that fast. But at least my bottle cage stayed put.

I'll never understand why frame builders use aluminum bottle mounts in steel or Ti frames (not sure if there are problems with aluminum/Ti other than it being fairly soft and easy to strip).

When I had my LeMond painted the painter looked at the frame and suggested we replace the aluminum bottle mounts with steel ones (since my frame is steel). There was bubbling of the powdercoat where the two dissimilar metals were joined and would likely have been a problem down the road if we left them in there. The few grams lost in going with steel is more than offset by the durability and strength gained IMO.

Just a minor rant on my part. Glad you got it sorted out.

That was almost exactly what the guy at Capitol Hill Bike said.
