Thoughts on 2012 Trek DS 8.5

Hi,

I have a chance to purchase this bike for around $550.

It appears to be in good shape but it doe not have the Isozone frame.

How much difference does this frame make?

Is this bike worth it if the Isozone makes a big difference.

Is there anything else I should consider?

Thanks,

John

I had read your post when you first wrote it. My first thought was: "There are tons of bikes out there that are better than the DS 8.5 that don't have an Isozone frame. Why would that be a deciding factor?" But then I moved on to something else and never responded, until now.

If a DS is the type of bike you like, it sounds like a good deal. I bought a brand new DS8.4 in 2012 for $800 and love it, I wouldn't pony up the *new* price for a 8.5 given the difference, but at $500 if it is in good shape then good for you. The older DS frame is thicker more mountainy (yes I made that up and the spell check doesn't like it) than the new one, and I like it better to be honest. The ISO zone is some rubber in the frame, I have never tried it so I can't comment if it is worth having, but I certainly don't feel like I am missing out.

I would love to know what other bikes you feel are superior in that price range.

There's no doubt the IsoZone stuff works as advertised, but it would not be the deciding factor for me. $550 seems like a great price for an 8.5, especially if it's been used gently.

So really it comes down to your riding style, and what you want out of the bike. If you had your heart set on bump and vibe mitigation either through true rear suspension or something like the IsoZone setup, you're bound to be disappointed. Then again, you'd also have regrets shelling out extra for some flex system out back if you think it will work like true dual suspension. You will be very disappointed if you're asking too much out of it, "Well, I want a bike for longer commutes and utility riding around town, but I also want to do downhill runs or super technical terrain every other weekend." But if it's more a superfluous feature considering your goals here, no worries.

I would be doing nothing more than pavement and light trail riding. I should test drive and see if the ISOZONE frame makes a big difference. I am not ready to make $1200, but for $500 I would consider it.

Thanks, any other info you feel would help, please don't hesitate.

When did I say anything about price range? My point is that there are lots of bikes out there without an Isozone frame. Just because the new 8.5's have this frame doesn't mean they are superior to others, it just means they are different. If you can get an 8.5 for $550, and it's what you want, the frame shouldn't matter. Especially with a $650 price difference.

You clearly stated you felt there were better bikes out there than the DS 8.5, but failed to list ONE. Why is that?

What experience do you have riding a bike with this ISOZONE frame?

My assumption is that the frame should be superior to a lower model DS like your 8.3, but you haven't provided any feedback on your experience with that frame.

I DON'T KNOW if that is what I want, if I did I wouldn't be here asking for other people's opinion on the subject, and YES THE FRAME IS A HUGE CONSIDERATION IN THE PURCHASE OF ANY BIKE.

If there is a huge difference, I could easily wait 1 year and get the 2013 DS 8.5 or even 8.6 that have the better frame and a similar price to this bike.

Feeling better?
You are out in left field in your interpretation of my posts. I am not knocking the Isozone frame or the 8.5, nor am I suggesting you not get an 8.5, all I am stating is that I would not let that sway my decision considering the price difference. But if you don't want the opinion of other members, then why do you ask questions?

You have not responded to any of my questions that I asked in response to your first response. I want opinions that ADD VALUE that help me decide, because I am no sure what way to go. That is the entire reason for the post.

Let's look at the facts:

You clearly stated you felt there were better bikes out there than the DS 8.5, but failed to list ONE. Why is that?

You seem to think the ISOZONE doesn't matter, but what experience do you have riding a bike with this ISOZONE frame? This will help me decide, which is the purpose of the post.

You stated the frame of the bike shouldn't matter in deciding to purchase the bike, why?

You stated if I like it get it, if I knew I don't post.

These things are all straight forward, I'm not sure why you don't answer the questions instead of rambling about things that don't help clarify the question.

That isozone thing would deter me from buying the bike.

There's been a many postings about the 12 DS models having some really bad squeally brakes. Some people claim a little disc adjustment fixes it, but it caused me to pause before buying a GF Utopia. Trek changed the way the discs were mounted to the frame for 13 and I don't think I've heard any complaints on those.

As to the brake issue, it may have depended on which DS model you are talking about. My 8.3 came with Tektro Novela disks and within a month they started squealing and chattering a lot. Very annoying. I tried adjusting them but lost the battle. I ended up swapping them out with Avid BB 7's and haven't heard a squeak since. I think the issue was more related to the Tektro brakes than how they are mounted, maybe it was a combination of both. The 2012 8.5 has Shimano hydros, so they may behave very differently.
