Described by Transition as a "big all-mountain bike", the new Blindside is a 7.6lbs frame (taking a pound off the weight of the older frame); and designed around 170mm/190mm travel. Although more pedal friendly it is clearly designed to be able to take big hits. The 2010 Blindside is a refined, well-thought-out bike & will probably go a long way to expanding Transition's fan-base beyond its traditional Pacific NW following.

The purpose of this article will be to overview objective features of Transition's new Blindside. There are no ride impression details as yet. A test bike will be shortly made available and ride impressions, photos and videos will be forthcoming in September. I plan to ride this bike in Whistler, Galbraith, North Vancouver, Squamish, Silver Star, drag it into the alpine and where-ever else I happen to go over the next few months.
|38.5lbs as built with 180mm coil front and rear travel|Geometry Highlights (more here)
|The allen bolted chip on the rear shock lets you adjust travel from 6.5 to 7.5"|
- 65 deg HA/72.5 deg STA
- In the medium size -> 1168mm wheelbase/436mm (46"/14.2") chainstay length
- 14.2" BB
|A familiar face graces the straight seat-tube; tall leggy riders who need to raise and drop the seatpost a lot will rejoice|-Frame highlights-
|Enough clearance for a 2.8" tire|
- At 7.6lbs this is not an overly heavy frame! For context, a 180mm coil front/rear build with downhill tires builds to 38.5lbs. That's a bike you can lug around uphill without too much issue.
- Geometry stays the same as the 2009 Blindside
- Welding is much cleaner with smooth surfaces on the welds
- New hydroformed tubes (toptube and downtube) - increases strength while decreasing weight
- Tapered internally welded headtube
- Using a removable "chip", rear travel is adjustable from 6.5" to 7.5"
- While designed for 180mm travel front forks, the Blindside is compatible with 200mm and 160mm/170mm front forks.
- Maximum rear tire clearance of 2.8
- Completely straight seat tube. Can accommodate long seat posts yet drop the seat all the way down too.

|Beautifully thought out cable-routing brought to you by Sam (check out the chainstay routed cable). Only one option for rear ends now - the common 135x10mm standard|

And just because this video is sick and because I won't be able to ever flow a trail quite like this here's a repeat of last year's Blindside in action:
