On my last day in Chatel, France, I had a chance to take a closer look at
Trek's 2011 Scratch Air 9. The 170 mm travel air sprung bike uses the same frame as the coil sprung Scratch, but should weigh in less for those riders who like to earn their turns. You can find all the details and specs inside!
Read on...2011 Trek Scratch Air 9
Trek's Scratch Air series is new for 2011, and although it uses the same frame as it's coil sprung Scratch brothers, both models are air sprung in both the front and rear to shave some weight and offer a different ride characteristic. The new Scratch Air's are designed to fill the gap left by the Remedy's switch to shorter 150 mm travel forks, and they could be just the ticket for riders who want to cover a lot of ground on a reasonably light machine, but will take full advantage of the bike's stunt friendly 170 mm of rear wheel travel. With this in mind Trek has spec'd both Air models with a dual chainring and bash guard combo, but there are also ISCG03 tabs if you want to mount up a chainguide.
Just as on the coil sprung version, the Scratch Air uses Trek's Full Floater system
2011 Trek Scratch Air 9 details
- Air sprung front and rear
- 170 mm of rear wheel travel
- Uses Trek's ABP Convert for active suspension while braking
- 12 x 142 mm rear axle (convertible to 135 QR with supplied hardware)
- Trail tuned Fox RP23 rear shock
- Fox 36 Talas FIT RLC, 120-160 mm
- Shimano 2 x 10 drivetrain
- E2 Tapered headtube
- Adjustable geometry via Mino Link
- Two Scratch Air models: Scratch Air 9 (shown), and the Scratch Air 8
A welded one piece EVO Link and all aluminum pivot hardware
Trek uses both their Full Floater and ABP technology on the Scratch Air that you've no doubt seen on their other models. In simple terms, ABP (
Active Braking Pivot) is Trek's name for their rear wheel pivot that rotates concentrically around the hub axle. The goal of the ABP system is to limit movement between the caliper and rotor as the suspension compresses and extends - the less the distance increases or decreases, the more active the bike will be under braking.
Full Floater refers to the rear shock not being bolted to the front triangle, instead it is attached to the EVO rocker link at the top and a short piece that extends from the chainstays beyond the main pivot. This gives Trek's engineers two places to tune the shock rate, as well as allowing them to build a slightly lighter due to not having to mount the shock to it.
ABP Convert allows the use of either the stock 12 mm x 142 mm rear wheel, or a standard 135 mm QR
The Mino Link allows you to fine tune the Scratch Air's head angle by half a degree and the bottom bracket height by 7 mm
Trek has built in the ability to fine tune the Scratch Air's head angle and bottom bracket height but rotating the pivot hardware that holds the seatstays to the EVO Link. The Mino Link adjustment offers just a half a degree of change to the head angle and 7 mm of bottom bracket height difference, but it is enough to fine tune the bike for the terrain or your riding style. As you'd expect, up front you'll find a E2 tapered headtube that makes for a lighter system than a full 1.5" setup, but stiffer and stronger than the 1 1/8th standard.

The build kit on the Scratch Air 9 consists of a mix of workhorse parts and components that should stand up to most any riders abuse. The two chainring and 10 speed cassette with it's big 36 tooth cog make for suitable mountain goat gearing that should compensate for the added weight penalty of the extra travel and burly parts. Suspension is handled by Fox both front and rear, with a custom tuned RP23 out back and a much sought after '11 Fox 36 Talas FIT RLC up front.

Mike Levy on The Scratch Air 9
Those riders who felt a bit left out when Trek decided to replace the Remedy's 160 mm travel fork with a shorter and lighter 150 mm version should be excited to see the Scratch Air released for 2011. Both air sprung models look to have a reasonable weight that will make ascending not too much of a chore, but the combination of slacker angles and more sag from it's 170 mm travel rear end should make for a very confident descender. The new Scratch Air platform looks to be an exciting addition for 2011.

I will not be owned in that way. Neither will I buy useless standards.
This is what happens in the bike industry, and to add to that, this is a culmination of the best technologies and engineering out there. My bike is amazing.
i do notz get it. why is there a single page about norco und for every bike of trek a whole article?
It's not enough that this brand now is custom E2 steers but now we need to find a 142 rear that only shimano makes if we want to run a 12mm rear axle.
I love trek don't get me wrong. But bike companies now a days are making too many standards.
like, short cage derailleur, new bars, new stem, no stupid seat post that goes up and down, and single front chain ring with a full chain guide.
Bike looks super sweet. I wonder what price the 8 will come in at.
66 is bit slack for a trail bike though?
What's up?
I think this post is quite impartial and based on facts...
Maybe it's the word "exciting" ?
Or is it cause it's not a "boutique" bike ?
2)cyberhawk, you will be seeing the 142 everywhere because it is far better than any axle system on the market. lighter and stiffer. This industry is still young and innovation is important so the sport and the industry (cycling) keep growing. So if you were ghonna say they can stick the syntace axle through the rear wheel, then you have hit the nail on the head.
aswel for the 15mm thru axle in front. also BS
150mm hub in the rear is good enough..!
they are making AM parts now.. so QR is xc, 15mm is AM, 20mm is FR and DH
and so for the rear..150 dh,, 142 AM,, 135 XC,, that 142 is typical shitmano BS so is the press in BB 30mm like a bmx type.. getting the old in the new age again.. jeej (barf)
electro shifters.. have you seen it ? even more BS..
these are not my 2cts.. but a 100bucks.. take it to the bank
and your 100 bucks is more like 100 pesos.
142 mm hubs? No thanks - we've already got 150mm. The one good thing is that Trek set it up so that people can run 135's still.
One day, there will be a mountain bike category in between ALL MOUNTAIN and FREERIDE and we will be flogged with forks that have 17mm thru axles.
, they have to start changing around stuff to make some good old profit, and sadly all it is is supply and demand, for who has the shinniest newest most expensive bike now.
pink bike helped me want more and more,
so the 142mm crap, is the same thing as the 15qr, more new stuff to sell and then improve on, =more profit.
I love how everyone has go on to 9 spd, and now the hot trend is 10 spd, while I continue to ride my good old reliable 8 spd...
I find it so funny how people shoot something down just by a picture without any knowledge of the product itself. I'm going to go out on a limb and say that 90% of people have never ridden one and 100% of you have never ridden on as its meant to be ridden, so untill then, stop talking cause you really have no idea what you are talking about.
ATRAK:: ." They don't care what a bunch of weekend warriors say, they are listening to hardcore mega-avalance/ racers that get paid to do what they are doing and know what works!
I was @ the megavalanche.. did not see many peeps getting payed to ride there.. also racers use new products cause they are IN the spotlight and very good to use as comercial sales men..
sadly we bring in most of the profit for the companies..not the racers who probably lost their fun in riding and getting payed like you say..just to WIN..
did you even read yourpost before hitting Submit
Edit: Oh wait, you have a Session 88, that explains your blind ignorance on the topic...
@ bunkey, accualy that makes you ignorant because I know what a trek product is like, while you dont, so I know first hand that they make amazing stuff.
I'm saying its fads and trendwhores who keep the industry afloat by spending all their (parents) cash on 'the next thing to have', not what Pro riders choose to use as you previously stated. (And that goes for the entire industry - not just Trek).
Take Ipods for example, its an mp3 player, its designed to play music files just like any other mp3 player... However its limited to just mp3/aac audio, the output sound quality is dire (pretty fundamental flaw for an mp3 player I'd say), it is extremely over-priced, and iTunes is slowly making a monopoly out of the music industry... Yet EVERYBODY uses an Ipod because its a 'trendy' mp3 player...
The same applies to biking whether you like it or not (look how many people bought Demo 8's after Specialized signed Hill ).
