Eurobike 2010: New mid-range wheels from DT Swiss

Plus revamped suspension range

It's DT Swiss's higher-value mid-range wheels which will benefit from the biggest changes for 2011, rather than the top-end hoops which are out of reach for many. First and foremost are less expensive versions of the innovative Tricon wheels for both road and mountain.

The new R 1700 and M 1700 share similar rims and 'open crow's foot' spoking to the flagship models but forego the stress-reducing multi-piece hub shells in favour of simpler one-piece bodies and slightly chunkier axle setups. Additional cost saving measures include straight bladed spokes instead of butted ones.

The solid outer rim wall again lends easy tubeless compatibility and DT Swiss's hyper-durable star ratchet system carries over, too, but weights have gone up 100-150g depending on model and axle type – and speaking of axle fitments, the top-end XM 1550 Tricon is now available in a Cannondale Lefty-compatible version.

Cross-country riders will have lower-cost versions of the XR 1450 wheels, too, including the X 1600, X 1800 and X 1900, all with 24mm-wide alloy rims designed for 26x1.5-2.25in tyres. Double-butted stainless steel spokes are used on the 1600 and 1800 models but only the former gets the lighter and more durable star ratchet system; the others get a conventional two-pawl setup.

Big changes come with the new FR 2050 freeride wheels, which shed a substantial 200g or so from their predecessors for a more nimble feel, and there's also a pre-built 29in mountain wheel in the M 1800 29er

2011 suspension

The DT Swiss suspension range has also undergone a massive overhaul for 2011, including three new damping systems and a new air spring architecture. The top-end Twin Shot damper features externally adjustable low-speed compression and rebound damping, internally adjustable high-speed damping, and a three-position lockout dial (open, closed, or lowered) that can be retrofitted with a bar-mounted remote.

The second-tier Single Shot system moves the low-speed compression adjuster inside and goes with a simple on-off lockout system. Finally, there's an update to DT Swiss's Launch Control damper, which is aimed at long-travel enduro machines and continues to use a unique bump-activated lockdown system for fast gate starts or when starting to descend after a long climb.

Single-shot dampers can also be retrofitted with handlebar remotes if desired

All of the DT Swiss fork range will include the updated ABS Auto Balancing Spring system. Similar to RockShox's Solo Air, ABS will use a single valve to charge both positive and negative chambers, yielding an apparently supple and linear stroke with fewer parts and less maintenance than a two-valve system.

Sitting at the top of range is the cross-country race-oriented XRC 100 with 100mm of travel, 28.6mm aluminium stanchions and carbon fibre lower legs with 9mm quick-release dropouts. The 'Race' edition adds a carbon crown and steerer, bringing the claimed weight down to just 1,170g.

The more trail-friendly XRM offers 100mm of travel as well but steps up to stiffer 32mm stanchions, DT Swiss's novel Torsion Box hollow-arch magnesium lowers, and optional 15mm through-axle dropouts. A tapered 1-1/8 to 1-1/2in steerer will be available, too. Claimed weight ranges from 1,550g to 1,665g depending on configuration.

Need more travel? The XMM forks share the same features as the XRM but with 120mm or 140mm of travel and claimed weights between 1,650g and 1,765g. Alternatively, the XMC subs in a lighter weight carbon lower leg assembly, which brings the weight down to just 1,570g.

Finally, there are the 150mm-travel EXM (magnesium legs) and EXC (carbon legs), offered exclusively with Launch Control II dampers. The EXM will be offered in both 9mm quick-release or 15mm through-axle versions while the EXC will be quick-release only. Claimed weights for the two forks are 1,675-1,770g and 1,575g, respectively. 

Prefer no travel at all?  DT Swiss have added the fully rigid XRR fork to their lineup for 2011 with carbon legs, crown and steerer, plus magnesium open dropouts. Claimed weight for the 26in version is a paltry 585g while the 29er version adds just 10g.
