    Trek 7.3 or 7.5

    Really torn between the Trek 7.3 an 7.5. I'm mostly using this bike for commuting, in Manhattan and Brooklyn, doubt I'll ever be going more than 20 miles in a day. Is the 7.5 worth $250 more? I don't want to have to upgrade again, but wonder if the difference in these two bikes is that noticeable.

    I'm upgrading from a too-small Trek 7000, I want something a little faster and lighter and better-fitting.

    Thank you for your help!

    If you are only using it for commuting, I would suggest you put this into your decision making process. If you are commuting over the winter when the roads are salted, beware of the winter damage it causes.

    i hear that manhattan is flat. if this is the case, you'll often use only the rear derailer. deore is nice. if your streets have a lot of potholes maybe you should consider the trek 4500 mountain bike with fat slicks for a comfy ride. the rim width of your bike will limit you on how fat the tires can be. i agree with rivendell that i'll go for fat, comfy tires and compensate with slicks + better engines. you may not prefer that but just a thought.

    your question is a good one and i'll wonder the same analogously later this summer when i get a mountain bike.

    what is the advantage of a 9 speed shifter, different cassette, and better front derailer? will the deore rear derailer perform better with deore shifters vs ef60 shifters? do the shifters, cassette, and front derailer of the trek 7.5 take better care of themselves over the long run than on the 7.3? i read on the forum that entry level derailers work just as well as midrange i.e. sora vs 105. well then besides a few grams of weight, why would anyone get the midrange vs the entry level? these are questions i wonder.

    The components are worth the price differences.

    I would buy that too, I think.

    I have a 7.3 FX, and it's a great bike. The price difference to 7.5 seems like a lot to me, but I've never ridden a 7.5. The only things I'd like to upgrade on my 7.3 are the seat and the pedals, but that's the case with most bikes.

    The 7.5 is equiped with a carbon fork,if i am not mistaking. I had ridden over 1,400 miles on my 7.3 without any adjustment,recently, i had removed to chain and soaked in Simple Green,scrubbed and rinsed in hot water,lubed and installed,the chain now is quieter than ever before and my average speed had picked up by.7 mph.

    According to the site, the 7.3 has a 11-32 cassette whereas the 7.5 has a 11-26 cassette.
    The components on the 7.5 are definately better, but if you realy need these depends mostly on your riding style.
    An 11-26 9-speed cassette wil give you more intermediate gearing options compared to a 11-32 8-speed cassette forsure, but again: this all depends on your riding style.
    The bike you have now has a 14-34 7-speed ... those are pretty low gears ... the question is: have you ever used your lowest gears?
    If the answer is yes ... the 11-32 has lower gears ans thus is more suitable for you.
    If you are more of a speedy and racy biker ... the 11-26 9-speed of the 7.5fx wil definately serve you better

    well I rode both bikes this evening and wow is the 7.5 a very nice ride - smoother shifting, easier on rough streets, really nice! Still trying to decide, can't say that my relatively short commute is worthy of such a nice bike, and also worry about the flashiness of this bike (I'm looking at the black bike with the red strip on the tires) - I don't always have the option to park inside in NYC.

    7.3 is great

    I have a 2007 Trek 7.3FX. i can't vouch for the 2010 models, my cousin just got the 7.2 and likes it. i commuted in both frederick and baltimore maryland areas and the bike has held up strong. i've gotten bar extensions on mine, and wrapped the whole set up in grip tape, i've also added a rear rack, lights, and reflective tape here and there.

    I've had the bike for a few years now, the seat is on it's last leg but when i first got it it just took a little bit to let my body adjust to it. after a few rides it was comfortable.

    The bike is fast too. great speed for a hybrid, and the long flat handlebars really let you add torque when you're pulling up those big hills.

    i always recommend the FX line of bikes to people who are commuting or recreationally ride.

    The most important thing is comfort. i personally don't think the 250 is worth it for such minute changes of what you need.

    wow this is a long post.

    I opted for the 7.5 over the 7.3 after test riding them. The 7.5 has a nicer set of wheels, carbon fork, shifts seem to be nicer and has better gearing for the riding I like to do. I liked the saddle on the 7.5 better, surprisingly I haven't changed it out yet as it has proven to be quite a comfortable saddle. I'm not going to lie, but I liked the black color over the 7.3 options too.

    In the long run, the extra money wasnt all that much for the differences to me, but the 7.3 is a nice all around bike too.
