Drilling holes in the frame? Ok to do or big no no?

I just picked up an old schwinn Super Le Tour 12 speed. It will be use primarily as my commuter until I get something better.

Last night I went to install the bottle cages and realized it has no holes to do so. Same problem when I tried to install the back rack.

So would it be ok for my to whip out the drill and put some holes in there to install these things or is there a better way to handle this?

Thanks

As long as your careful, I don't see a problem with it. Here's a link for waterbottle tools, and mounts.

There's a better way to handle it. P-clips are a sturdy, easy way to attach the rear rack at the seatstays, and Zefal Gizmo clamps will do the same for water bottle cages. I've got an '83 Schwinn le tour luxe myself, and that's the way I've handled it-

YES indeed,this man has the right idea but you MAY need to start-off with a teeny-tiny hole, holes get too big real fast with a drill. As far as compoming the integrity of the frame.. naahhh, I'll allow it !

Get bottle cages where the mount holes are on a tab that a screw clamp can get around. Cut the clamp strap to length and cover it (except for 1/2") with heat shrink tubing, and you are set. This will protect the paint and look better. Perormance has the right cages, and the hardware store has the clamps and heat shrink. Don't overtighten. bk

Don't just drill or use self tapping screws since eventually they will work loose and you have no reinforcements on the frame tube to support the screws which could either tear the frame tube or crack it or buckle it.

There is a better way with either a home made system using hose clamps which looks junky but it's cheap; or use the stuff that Minoura has for various water bottles holder clamps depending on what you need: http://www.minoura.jp/index-et.html

As far as rack mounts go depending on how much weight you want to carry, the best way for light travel up to 25 pounds is with a seatpost rack: http://www.nashbar.com/profile.cfm?c...cat%3A%20Racks

Or if you must have panniers, you can get some to mount onto a bike that doesn't have the bosses to handle the racks, scan down thru the page to find either a large bags that fastens to you seat OR a pannier system that mounts to the frame: http://www.peterwhitecycles.com/carradice.asp

Go to Wal-Mart or K-Mart.

Yes, I said it.

Last time I was in there, (which, admittedly, has been some time) they offered a bottle and cage that came with a metal clamp that wrapped around the tube. It looked like an otherwise normal, if somewhat generic cage and bottle.

I bought a cheap rack off Nashbar about two months ago, (I think it's a delta) that came with straps.

Good luck with it - and congrats. My first non-department-store bike was a used '89 Le Tour. At one point there was contact with a large pickup. It added a minor curl to the down and top tubes. I replaced the fork and went right back to riding. Rugged bike, that.

I haven't seen the Walmart variety of stuff so they might be ok. But the cages that use velcro straps don't work real well. I had one, and the weight of a full bottle kept moving the bottle and cage to the side of the frame everytime you hit bumps, no matter how tight I made the straps so I was forever moving it back in line with the frame. Works great though with an empty bottle!

Why not just teach yourself brazing and add some real mounts? OK...besides the cost, time and repainting, that is.

I'm with TrekDen, the riv-nuts are the best fix for this situation, and your LBS may be able to do it for a small fee if you don't wish to invest in the tools. Personally, I look for any excuse to buy tools.

GOOD IDEAS
It's not like we're discussing your bike for example. The OP has an old LeTour,a commuter. The "value' of the bike has been taken into account by most of us, MOST. The owner of said bike sure has anyway. He most likely drilled it already. OK, you want to get squeemish,look in the fixed gear forum or on e-bay if classic frame preservation concerns anyone,not mention compromising frame integrity.

I haven't drilled anything yet. I picked up some self tapping screws if I decide to go that route. I am going down to the shop in a bit and I will talk to someone while I am there.

Thanks for the advice so far.

Ugh. Velcro seems like a poor way of keeping a bottle in place. The steel clamps looked like they might mar the paint, (cut up an old tube and use that for protection if you're worried) but they seemed like they'd keep your water in its place.

Here's a pic of a Zefal Gizmo clamp like I mentioned earlier. I think they look kind of cool, and they work great: http://www.yellowjersey.org/GIZMO.JPG

My cage that didn't work real well was made by TwoFish; this is what it looked like: http://cyclocrossworld.stores.yahoo....fiswatbot.html

But stay away from it.
