First Look: RockShox debuts an all-new SID

The SID fork has been around for a long time now, and has always been RockShox’s premiere cross-country fork. It even dabbled in the early trail bike fork arena with a double-crown model that had a whopping (for the time) four inches of travel and more recently with 120 mm models for lightweight trail bikes.


Now that short-travel trail bikes are using Pikes or Revelations, this leaves SID room to focus on its original intent: Superlight Integrated Design. That means a full redesign and some trickle-down trail bike tech.

All four SIDs now max-out at 100 mm of travel, letting RockShox optimize for stiffness and weight, including shorter air shafts and upper tubes. The magnesium lowers have a full redesign, including Torque Cap compatibility, which promises increased torsional stiffness when used with a Torque Cap hub, but you can still run any 15 mm hub.

The Solo air spring is more linear, but can be tuned with Bottomless Token spacers for heavier and/or harder charging riders. A Jounce bottom-out bumper (from the RS-1) helps to prevent harsh bottoming, and updated seals lower friction and improve cold weather performance.

Probably the biggest news is the addition of the excellent Charger damper in the World Cup and RLC models. The Charger damper, which is used in the Pike, Lyric and Boxxer is well-loved for its performance and easy set-up.  In the SID, the Charger has only Open and Lock positions, with a compression adjuster for the Open position.

The SID XX and RL keep the older (but still quite serviceable) Motion Control damper, but rest of the upgrades remain the same. All forks come in either 27.5 or 29 inch options, 80 or 100 mm of travel, 42, 46 or 51 mm offset and 110×15 Boost or 100×15 spacing.

All forks will be available June 2016.

First Look: OneUp Shark 10-50 11 speed drivetrain conversion

OneUp was one of the first, if not the first, to market wide range adapters for 10 speed drivetrains. It is not surprising to see the same thing for 11 speed.


The Shark is a 10-50 “system,” as it requires a range of components to make it work:

  • OneUp 50 tooth cog
  • OneUp 18 tooth cog
  • OneUp 10,12, 15 tooth mini-cluster
  • OneUp derailleur cage
  • OneUp Minidriver freehub body
  • Shimano 11 speed derailleur and shifter
  • Shimano 11 speed 11-42 cassette

Let’s take a look at the pieces:


The 50 tooth aluminum cog is installed behind the cassette.


The 18 tooth steel cog replaces the 17 and 19 tooth cogs in the cassette.


The 10 tooth cluster replaces the final three cogs on a the cassette. (In case you are counting, that is 5 of 11 cogs being replaced, or  about 45 percent of the cassette. Makes me wonder when OneUp will just make an entire cassette.)


Shark Cage (shown installed) replaces the stock cage on Shimano M9000/M8000 derailleurs. The upper pulley has 50 percent more offset to the pivot. When shifting to larger cogs, the cage rotates forward creating enough clearance for that big 50 tooth cog while keeping the pulley close to the smaller cogs as well.


The Minidriver is a shortened standard cassette body which allows the 10 too cog to hang off the end. This is a simple design with no patent issues, so anyone can develop one to fit their hubs. Expect versions to fit DT, Stan’s and Hope hubs to start.

If this sounds like a lot of parts to swap, it is, but many riders will find it worth it for the range.


Notice that you get extra gearing on both ends with the 10-50 cassette and a 34 tooth ring vs the now-standard 10-42 x 30t SRAM system.

You can pick and choose from the pieces, so for $125 you can get a kit with the 50t and 18t cogs and the Shark cage and up your climbing game from 11-42 to 11-50 without messing with the cassette body. Or you can add just the 10 tooth cluster ($45) and minidriver (40) to the other end of the cassette for harder gearing.

If you hurry you’ll be able to snap-up the 50t kit, but the minidriver and 10t cluster will be back in stock in May. This works solely with the 11-42 M8000 XT cassette, 11-40t cassettes can be converted to 45t.

Inside Line – SRAM NX 1×11: 1x for entry-level bikes

SRAM has been slowly trickling down 1×11 tech to lower and lower price points over the last few years, but with the release of this newest 1x group, even those with a less-than-sizeable bike budget can get in on the 1x evolution that is taking over mountain biking. Read on for full details and our analysis.

SRAM_MTB_NX1_Cassette_PG1130_Side_M SRAM_MTB_NX1_RD_Side_Black_M SRAM_MTB_NX1_Shifter_Front_Black_M SRAM_MTB_NX_Crank_1000_32T_AL_Spider_30mm_Side_Black_M

Pictured here is a basic group with only a few of the well-thought-out options: 11-42 11 speed cassette; crank with 28, 30, 32, 34, 36, 38, 40 chainring options; trigger or grip shifter; a $14 chain and a rear derailleur that won’t make you cry if it gets crunched on some rocks. Let’s have a look at the specific components:


PG-1130 Cassette

$79 | €89 | £68

Notice this is an 11-42 cassette, not the 10-42 range on the more expensive groups. This means it can fit a standard Shimano-splined cassette body, and is a hell of a lot cheaper than the 10-42 cassettes as well.

Claimed weight is 538 grams, substantially heavier than the GX 1150 10-42 cassette, and a little more portly than Shimano’s M8000 11-42 XT-level cassette.


1×11 X-HORIZON™ Rear Derailleur

$74 | €76 | £58

All the same features as the more expensive derailleurs, just a hell of a lot cheaper and a bit heavier. NX comes in at 322 grams, vs the $115 GX derailleur at 265 grams.


NX Trigger Shifter 

$27 | €28 | £22

The shifter may have the most stripped down feature-set of any of these components, missing out in the ergonomic adjustments and Matchmaker compatibility. But it is $27, which is less than a case of whatever craft beer you have in your fridge. At 142 grams it is only a little heavier than the 122 gram GX shifter which is $42. Also, SRAM still makes Grip Shift. Some people still ride them, I guess. If you want one, it is $33. Knock yourself out.




1x X-SYNC™ Crankset

$116 | €120 | £92

These are pretty simple functional cranks, with a ton of options. So many options, I’ll let SRAM cover them all:

  • BB COMPATIBILITY: BB30/PF30-68/73mm, GXP 100mm/ PF GXP 121mm, GXP PF GXP 68/ 73mm
  • CHAINRINGS: 28t, 30t, 32t, 34t, 36t, 38t, 40t
  • CRANK ARM LENGTH: 155mm, 165mm, 170mm, 175mm
  • BB SPINDLE INTERFACE: 24mm, 30mm
  • GUARD: Aluminum Guard, No Guard
  • CHAINLINE: 49.0mm, 52.0mm, 66.5mm
  • PART WEIGHT: 80-780g


PC-1110 Chain

$14 | €14 | £11

A $14 chain that works with any SRAM 1×11 group. Will probably work with any Shimano 1×11 group, too. Includes a PowerLock connector. Strangely enough, if you want a PowerLock to connect your Shimano chain, because Hyperglide pins are kinda off-the-back these days, it will cost you $17. That $17 PowerLock is shiny, vs the matte-black connecter with the $14 chain, but you get a WHOLE CHAIN included at that price. I know what I’d buy.

The 1110 chain is claimed to weight 232-273g, which is LIGHTER than 258 gram X1 chain. I predict SRAM is going to sell the crap out of these things.

Our Take

All told, this is a $310 upgrade for a fully-featured 1×11 drivetrain that will work with your current wheels. Use your old crank set paired with a $20 SRAM steel X-Sync chainring and get that price down to $214. And long term cost from consumables (cassette and chain) is a lot easier to swallow as well.

SRAM was silent about the 11 tooth vs 10 tooth high-gear range. It will probably be noticeable to those of use used to 10 tooth cogs. But, in all honesty, on modern trail bikes, I only ever want slightly easier climbing gear, and almost never want something to go faster on the flats. Regardless of slightly less range, a $300 1×11 group is going to replace a lot of Shimano Deore level 2×10 drivetrains on complete bikes real soon. And I would expect smart companies to offer some interesting builds with high-end suspension matched to the NX group to keep price in check but performance very high.

This may be bigger news that the original 1×11 drivetrain release in 2012. And maybe even bigger news than the rumors of even wider range 12-speed cassettes waiting in the wings.

Some things to be excited about

  • 155 and 165 mm crank lengths are very, very hard to find at this price point. I know what my kids will be riding soon.
  • Fat bikes (with 4 inch tires) have another crankset option
  • Lots of chainring sizes that should allow this to be used on everything from all-mountain bikes to flat-bar gravel bikes.
