The 2008 Trek 1.5 is formerly known as the Trek 1500. As mentioned in the Trek 1.2 review, Trek has updated, and reorganized many of their model numbers in 2008 from the thousand (1500 last year) series, to the x.x series (1.5 this year).

Once again, Trek doesn’t disappoint as the Trek 1.5 is a decent value, with a stiff, and light frame. The components have seen some significant changes, but as you’ll see, not all of them are for the better this year.

Visuals

The Trek 1.5 is actually quite stunning compared to last year. I really like the red and white model as it looks sleek, and speedy. Of course, this is just my humble opinion, and yours may vary. Be sure to click on the pictures for a larger version to get a better look.

Frame

The frame is fantastically rigid, and stiff for a mid-grade aluminum frame. The 1.5 includes the standard, road absorbing, Bontrager carbon fork. The carbon fork isn’t unexpected at a bike in this price range, but it’s definitely welcome. This year Trek has included a slot in the fork for its Speed Trap sensor.

Drivetrain

Trek has replaced the Shimano 105 components of yesteryear with Shimano Tiagra and Sora (front derailleur). This is a bit of let down in that it’s definitely a cost saving (for Trek) downgrade. I believe the Shimano 105 setup went to 10-speed for the 2008 models, so Trek is saving some money by sticking with the 9-speed Tiagra. The most bizarre downgrade has to be the Sora front derailleur (FD). Sora FD’s are not known to be very good, as they need constant adjustment, especially on a triple.

Components

The Bontrager saddle sits on a carbon seat post. It’s a pretty familiar setup for anyone that owns, or is looking to own, a Trek road bike. Trek went with the SRAM PG950 cassette (last year was the Shimano HG50), and a Bontrager Sport crank.

Warranty

All Trek bikes include a lifetime warranty on the frame for the original owner, 5 years on most of the Bontrager parts and the fork, and 1 year on pretty much everything else.

Conclusion

The 2008 Trek 1.5 is a pretty good road bike for the folks that want a step up from a Trek 1.2. It’s too bad that so many of the components were downgraded. That said, the frame is quite good, and is worthy of being upgraded. The drivetrain is 9-speed, so it should be fairly easy to find some higher quality (possibly used Shimano 105′s) components to upgrade to.

The MSRP of the Trek 1.5 is $1039.99, but you’ll surely find it for less.

As always, make sure to visit your local bike shop, ask lots of help, and get properly fitted before purchasing any bike.
