How much punishment can my Trek FX 7.3 take?

It's essentially bone stock right now. Can I expect to be able to drop off curbs and the like regularly?

I guess I more worried about bending a rim (Bontrager Camino) than anything. It has 32c slicks right now (running 95 psi for now), thinking of going to a 35c with light tread sometime. Will that help at all? I need this thing to last. I only weigh ~140 lbs, but could be carrying 20 lbs or so on the back regularly.

I'm having a hard time learning to bunny hop this thing.

I'm showing my lack of knowledge and experience here, but that's how you learn sometimes. This is the closest thing I've ever had to a road bike, I'm not really sure what's considered acceptable. Thanks

I would.

I think with a rigid frame that bike should be fairly bomb proof, and you probably don't need to change the tires. 32c is plenty wide for pavement, and tread is pretty worthless unless you're riding on a substance that is actually softer than the tread itself (not pavement).

You're right to be concerned about the wheels, though, but stock wheels are notoriously cruddy. What's the spoke count?

Doing this sort of thing will be tough on the bike, but bikes are meant to be ridden, goddamit! I'm not sure I would buy a bike I couldn't hop off at least small curbs with, or bunny hop potholes.

They are 32 spoke and supposedly double walled.

I want the tires for riding on bike paths, just figured the bigger size (I remember them being a bit taller too) would help out while also providing a little more cushion for the rim. They would be the same tire that the fx 7.2 comes with and just happen to be treaded. Can's say that I've looked into alternatives.

With the aluminum fork, there is a lot of vibration even on pavement with loose gravel. Considering a carbon fork in the future too. I wish I could have ridden the 7.2 on similar surfaces to get a feel for if they (tires) will help or not. It might not make dramatic difference either way.

Should be totally fine especially considering your weight.

treads are useless...contact patch so small on bike tires anyways...

If you're worried about flats pump up the tires a bit more

FYI I was 240 lbs, riding a Gary Fisher Utopia with low spoke count Bontrager Select wheels and I rode down stairs and over curbs for years. The bike is still rock solid, haven't even trued the wheel in the 6 years I have had it.

You really don’t want to know what I have put my Trek 7.5 FX through. But in general running off curbs is a lot easer on the bike then running into curbs (that is to say it’s the sharp jolts up or sideways that does the most mischief to the rims.)

I have a '05 model 7500FX with 20 spoke wheels. I am worried about bending them, but they look cool as heck.

^^^ That’s what I have and it takes all the following to do them a mischief: Carrying 200+ lbs of cargo, traveling 20mph+ and hitting a real nasty sharp edge bump. Those rims are a lot stronger then they look IMHO.

I would think curbs would be no problem. I weigh about the same and had a car run me into a deep pothole at close to 20 MPH. The sharp edge on the other side sent me and the bike airborne knocking both feet loose from the clips. I expected a tacoed wheel, but the wheel came out fine.

I would not recommend trying this on your own. It proved to me the stock wheels were strong enough for anything I can put the bike through.
