Trek 7.2fx vs 7.3fx tires on gravel/dir

I *think* I am down to my final decision. Waiting for the shop to get in a bike closer to the size I need so I can do a test ride.

My concern is the tires between the 7.2 and the 7.3. The 7.3 look almost bald and I am concerned I won't be able to get through the short dirt roads I have to cross to get onto our bike train.

Also, is it worth the upgrade? I like the handlebar grips better on the 7.3 and I think the pedals are better too.

I already decided against the Scott Metrix and the Sportster (although the Sportster was comfortable) and the Specialized Vita/Sirrus ( didn't feel in control). The Trek's have been the best so far. I am trying to locate a store that carries Jamis.

Thanks,
Pam

I have a 2011 7.3 FX, and love it. In general, I think moving up the FX line, each step is worth the jump if it is within your budget.

However, I wouldn't make a bicycle choice based on consumable items like tires... although I would consider whether it would fit the type of tires I want to use. If you want something with more tread, my 2011 can easily handle 35 mm cyclocross tires... and I have squeezed in 40 mm tires (very little room to spare, but they fit).

Or go with a 32 mm tire with tread that you would like if you are ok with the width. You could even sk the shop if they would give you a deal on a set of tires you would like more, or if you are bold, ask if they would just swap the tires, since they could be able to use the existing tires for replacement for people who insist on the same tire the bike came with.

Neither tire would be much good in mud. However the 7.3 has Bontrager AW1 Hard-Case Lite tires. The AW stands for All Weather. I'd think those tires would work better.

Ditto what Darwin said. Tires are easily changeable.
IF I were to buy a brand new bike, I'd look seriously at the 7.3FX vs the 7.2 FX.
Main reason is the 9 speed vs 8 speed. 9 speed cassettes come in a much wider variety of cog combinations than 8.
For people that don't do steep hills, something like a 12-23/25 cassette makes the bike much more road friendly.

I got the 7.3 over the 7.2 for the extra speeds as well. If I had to do it again, I'd upgrade to the 7.4 for the carbon fork, more forgiving than aluminum.

It really isn't. All you're getting with carbon is weight reduction, I rode the 7.3 and the 7.4 back-to-back at my local Trek dealer and found both rides to be equal. I rode the full carbon 7.7 and that was a nice ride but the usefulness of a carbon fork on a full aluminium hybrid bike is overstated, it's a very small and marginal improvement.

As for the OP, there's a laundry list of reasons i'd go with the 7.3 over the 7.2, you're getting a lot of upgrades for not a huge price increase.

Put whatever tires you want on the 7.3, but IMO, a very bad idea to make a purchasing decision based on stock tires. I have switched out stock tires to something better on most of my bike purchases.

as for whether the stock tires would handle the dirt roads you have to ride, a picture is worth a thousand words. Also, how far will you be going on this dirt road? 1/4 mile? 1 mile? 5 miles?

replace the tires? LBS here does that on new bikes and puts the other new take-of tire back for resale .

I disagree. I have a Sirrus, Comp, with a carbon fork, and the carbon rides much smoother than aluminum forks. It really is noticable. Road buzz is almost non existent. As is handling of ordinary bumps.

Granted, its not as smooth as my suspended crosstrail, but it really is a much nicer ride.

After having this Sirrus, I would definately opt for a carbon fork.

I run 28s (Bontrager hard case AW) on my 7.2 FX over gravel paths and woodland trails with zero issues. And on the road they are so much nicer than the fat stock tires.

Currently, you have to spend some money to get compliant carbon fiber. The cheaper stuff is merely light.

Semi slicks or semi knobs work fine on dirt roads, but as usual YMMV.

As others pointed out, choose a bike based on non consumables. frame > fork >wheels >compnents > consumables

+1

I was using the Bontrager in a size 28mm for a while and they were fine on the vast majority of rail-trail and crushed lime-stone type trails. Where they fell short was riding the C&O canal tow-path, but that's an especially rough trail by recreational riding standards... it was also more of an issue running a 28mm tire at too high of a pressure; the same trail with a 32mm tire and lower pressure would have been fine. A more aggressive tread pattern does have advantages on gravel if you decide to sprint but unless you are in a race, that doesn't matter. They stop about the same.

Although "woodland trails" is kind of vague... I wouldn't use slicks on a trail with rocks/gravel bigger than say a marble. Not for more than a mile, at least.

That's one of those things where a short test ride wouldn't make for a noticeable difference... the (potential*) harshness of aluminum tends to stand out after a four hour ride. A carbon-fork upgrade really is an upgrade, not just marketing (this coming from someone with no desire to own a carbon bike).

*I say "potential" because variations in tubing size and design also influence ride and comfort.

How many hybrid riders (ie FX) go on 4 hr rides? Not that many, I'd imagine. I do 1-2 hrs regularly and that's plenty for daily fitness rides though have done 3 hrs in organized charity rides but you do have several rest stops.

I know quite a few people that have taken multi day touring rides on hybrids... so it's not out of the question. Granted, as a percentage, that would be a minority (for that matter, the majority probably get ridden twice and then rot in a garage). I think a good number of them end up in charity rides and centuries, probably more than you think, actually.

Really just comes down to what a given person plans to use the bike for. That's why I hate these bike-forum discussions that always turn into "what is the correct choice?" The only true answer is that all choices are correct/best choices, and you have to understand the pros/cons and figure it out for a given scenario. I don't think enough posters understand that; they just want to be told what to do (as opposed to being given the info and left to make an independent decision). Speaking from personal experience, it was time to get a new bike when I started riding centuries on my hybrid, which wasn't pleasant.

I ride a 2011 7.3 FX but have gone in an opposite direction. I originally purchased the bike to be a training bike with short rides in mind but I have changed that line of thinking and now my rides have lengthened with thoughts of riding a century or two next year. The 7.3 did not make me happy on limestone or gravel with any loose or rough surfaces and I have now gone to 28mm tires and am using this bike as a road bike only. I also ride gravel roads and some MTB trails and have consequently purchased a Trek X-Caliber for that purpose. On my 7.3, I have flipped and lowered the handlebars and with using the lighter/narrower tires and going to clipless pedals, I have managed to improve speed by about 1-2 mph average over a 30+ mile ride. Imo, the FX line of bikes are basically flatbar road bikes (yes slightly heavier) and are not really designed for off road surfaces. Eventually, I plan to sell my 7.3 and purchase an aluminum frame/carbon fork road bike as its replacement.

I made a purchase today....after riding several bikes from different manufacturers. I purchased the Cannondale Quick 4. It fit me the best and was so very comfortable. I cannot wait to go for a longer ride!

That's the way to do it! Congrats! Have fun! Use a good lock and don't leave it sitting out where an opportunist-thief will see it. Grab a small bag and keep a few energy bars with you when you ride, and an extra tube, of course.
