2010 Nelson 1
Read on...
Opus offers two models of the Nelson, the less expensive Nelson 2 at an MSRP of $2960 CAD, and the higher end Nelson 1 that we're going to have a closer look at below. Both bikes are built around the same triple butted aluminum frame and feature Opus's Floating Pivot Point suspension that delivers 175 mm of travel and a 1.5" headtube up front. The top end Nelson featured here has an MSRP of $4160 CAD.
Opus has clearly put the Nelson 1 together with the demands of high end freeriders in mind. Up front you'll find a 1.5" head tube that not only increases strength and stiffness but will also let you run any fork of your choice down the road, be that the 1.5" Totem that it comes equipped with or a standard 1.125" steerer, or even the latest crop of tapered steerer tubed forks. Opus's choice to use the larger headtube size also allows the rider to fine tune the bar height or even headtube angle by installing headsets with different stack heights.

Hydro-formed top and down tubes curve to provide great standover room as well as clearance for any fork knobs that may have come in contact with the underside of the frame otherwise. If you do barspins on your FR bike, or are planning to, there is nothing holding you back on the big Opus. Cable routing takes a clean route beneath the downtube, although riders who hang there bikes over the tailgate during shuttle runs my take issue with this choice. The rear end is tied together with a 12x135 mm Maxle system for both stiffness and quick removal.
The Nelson's rear suspension
Suspension on the Nelson is a Floating Pivot Point affair with two short links joining the front and rear triangles. This system can be found throughout Opus's complete line of mountain bikes and is put to good use on the Nelson, the longest travel bike in their lineup. The Fox DHX 4.0 is not mounted to the front triangle, but instead floats between the upper and lower links. All pivots rotate on sealed bearings for durability.

The Parts...
Opus equips the Nelson to be a turnkey freeride machine with a nod towards reliability as opposed to light weight. RockShox and Fox tag team the suspension duties, both handled with coil instead of air. Out back a DHX 4.0 manages the 175 mm (6.8") of travel while allowing the rider to adjust rebound, ProPedal, and Boost Valve pressure. Opus spec'ed RockShox's long travel, single crown, 1.5" Totem up front. With 180 mm (7") of travel and adjustments ranging from rebound, preload, and Mission Control, the Totem should be ready for any freeride adventures you have in mind.
The cockpit sees an assortment of FSA goodies, including a Gravity-Lite 710 bar and Gravity-Lite 60 mm stem. Controls are handled by SRAM, Avid, and Truvativ. If you have some big moves planned you'll be stoked to see the use of Code brakes to slow this heavy hitter down. A big 8" rotor can be found up front and is combined with a slightly smaller 7" disc out back.
Other standout components include the not often spotted Geax Neuron tires wrapped around Mavic's EN521 rims, and Truvativ's Holzefeller cranks in a galvanized finish.

I like your bikes. My favourite is the Bee. I saw it at the Toronto International Bike Show and I loved it: here's my review ;-)
