Trek 5500 water in Frame(7 posts)

Trek 5500 water in Frameotfman

I purchased a new Trek 5500 in June of this year and I should add that I really like the performance/feel of this bike. The one complaint that I do have is after riding in wet weather like we have had much of the summer in the southeast , I can pull my seat tube out and pour out ~ 8 oz of water. Has anyone else had this problem with Trek OCLV ? Is there any way to correct this or do I just continue to pull tyhe plug and drain afetr rainy rides ?

You have to make a seatpost condomAllUpHill

OCLV frames are terrible about this. The other week, I thought I had poured all the water out the seat tube from any recent rides in the rain. Well, I took the bottom bracket out and poured out almost 1/2 cup right there too. I guess it had been lurking in the downtube and chain stays and didn't come out when I tried emptying the seattube. It's so bad I have to pour water out even if I just ride through some small puddles on the road on a dry day.

The solution is to seal up the area of the seatpost clamp with a section of old inner tube. You will need to cover up from the notch in the seat tube to an inch or more above the clamp. A road tube is too small to stretch over the clamp, so you have to use a mtb tube. About a 3 in section should do it. Then you'll need a really small piece of road tube (~ 1 in long) to seal the upper edge of the mtb tube around the seat post. Obviously you have to pull the seatpost to put all this on.

Water can get in through the headset area as well, although not as easily. If you want to be really thorough, make a similar "condom" for the upper and, espeically the lower headset bearings. Have to pull the fork out to install the lower seal.

Drill a 3mm hole in the bottom center part of the bb shell. Many bikes come standard with drainage holes in their frames.

Trek is a great company with one of the best warranty policies in the world but if you drill a hole in the BB shell of your OCLV you will have VOIDED the warranty in a BIG WAY!

If you would even consider doing this visit your Trek dealer first and ask them if it is a good idea.
lighten up it's only a small hole :) nmdivve

If I ride in the rain for a prolonged period of time, I always pull the seat post out and usually get some water out of the seat tube. Its no big deal. I've never gotten as much as 8 oz, but the amount doesn't matter. Just hang the bike upside down and let it dry.

Water will get into the bottom bracket as well. You can remove that if you're worried about it. I just ride it and figure the water gets out the same way it got in. With a carbon bike, rust is obviously not a concern.

I understand that most bikes do this ! I also own a litespeed ti bike that has the small hole in the BB shell for water to drain out. My problem with my Trek OCLV is, I shouldn't have to pull the BB, seattube, or anything else out to drain the water. I paid $3300.00 for this bike . Trek should if is possible design a OCLV frame that will drain itself. Drilling a hole in the BB will definitely work , but I'm not going to void my warranty . Is the condom thing the only way to correct this or is it something that all of us Trekies must live with ?
