FS Giant Trinity A1 Triathlon Bike
POSTED: 8/08/11 7:53 PM

2007 Giant Trinity A1 (purchased new 5/2009)
Size Small – compact frame (sloping top tube) so this should fit a wide range of riders.

Well cared for. Never crashed.

It is a great frame! Intelligent Tri design and good geometry. (see Slow Twitch Piece below).


Asking $1,000.

Major changes to original spec of the bike:
Handlebar: Vision Alloy Base Bar 26.0 x 40cm Black with Vision R-Bend extensions (nicer and more aero than original equipment)
Stem: Dimension, 70mm -35deg
Brake levers: Vision Alloy
Saddle: Performance carbon saddle, black (or optional Vision AeroMax Tri, chromoly rails, white)
Crank: SRAM Rival, 50/34 (compact) 170mm

Selling with the wheels that came with the bike. Similar to the Xero wheel set pictured in the Giant Brochure. To be exact Xero XGR1 wheels. They are a nice set of Aero, minimally spoked, Aluminum Deep Rim (32mm) Wheels. They would do fine for training and most Tri's (unless you want to rent some Zipps for your big A race of the year.)


Here's a Slow Twitch Piece on the Bike:

...::: TRIBIKE MIKE :::...

PREVALENT FEATURE: Ready for first tri bike. ALSO: Been in the sport 1-3 years, been doing tris on older but serviceable road bike; wants a steep seat-angled bike; wishes to stay below $2000.
So you think you're ready for a tribike? Let's make sure. Do you own a road race bike? Got clipless pedals down, and the gears, you know how they work with intimacy?

Do you have some sort of aero position rigged up on your road bike, and you can ride quite well in that position, without getting freaked out? Do you find yourself riding on the nose of the saddle, pushing your saddle forward on its rails, and you still ride on the nose?

Okay, you're ready for a tri bike.

You've got two criteria at the top of your list: It's got to get you in the right position, and that equates to a bike with a geometry that matches your personal fit coordinates. It's also got to fit inside your price range, and that's below $2000. Happily, there are a nice selection of bikes that will do this.

You can get the world for this price, but it didn't used to be this way. Bikes are like computers -- they don't go down in price much, but the value at target price points keeps improving. Nowadays you can get sub-20 pounds, aero tubes and posts throughout, faired rear wheels, 10-speed Ultegra or Dura Ace derailleurs, and some carbon.

Best, yet, many come in top geometries. In fact, some of our industry's best geometries are available in these bikes' frames, because they're typically aluminum, and bike designers don't have to wait out a mediocre geometry in order to amortize a previous, less ergonomic, carbon frame's mold.

Let's get down to specifics. Giant's new Trinity Alliance 1, (A1) costs $2000, and is geometrically just what you are looking for. In fact, this is a perfect example of the cheaper Giant being better than the more pricey all-carbon version. Why? Because it's newer, and the geometry is updated.

The Trinity A1 is a largely carbon bike. The aluminum "chassis" folds seamlessly into a carbon, sort of like a running shoe's durable outsole attached to the more compliant midsole. You can see from the photo what's aluminum versus the black part of the frame, which is the carbon.

The parts kit is slightly downspec'd from some of its competitors, and that's due to the more upscale frame construction. The shift system is Shimano 105 with Ultegra, Tektro brake calipers, and FSA crank and Xero wheels. The aerobar clip-on is a quite nice Easton Aeroforce, and all are accented with a Giant-branded stem, saddle and so forth.

You've got four companies out there all offering bikes in this price range that have the frame features described several paragraphs above, as well as the geometries you'll want. Giant is one of them, and it's got the most feature rich frame materials...

I may be interested. How does this compare to cervelo p2?

Giant is a very aero bike. I had it in the wind tunnel in SC last month and it was very close to a 2011 Super Bike. Within 16g of the Super Bike. (At 20mph, his equates to about 1 watt power difference, so almost no dicernable difference.)

Both Cervelo P2 and the Giant A1 have the same cockpit and similar component specs. The 32mm deep wheels on the Giant are bit nicer (same depth as Zipp 202s) and will do for most races. The “Economical price point” wheels on the P2 are only 24mm deep and are closer to box training rims than anything you would want to race on.

But to be honest, the 2011 P2 is a nicer bike. All carbon frame vs. Al/carbon hybrid frame for the Giant A1. The P2 frame is likely a bit more aero than the Giant (although this does not equate to tons of time saved as you can see from above). So if you have $2,400 the P2 would be a great choice.

But the Giant is $1,400 less. So bang for the buck. Or $ per time saved the Giant is a better value. You could save the $1,400 towards a future set a race wheels that would save you a lot more time than the P2 frame.

I hope this has been helpful. -A

Oh, and Giant had been to the AG podium a number of times in the last few years. It has good race Karma.
