Truvativ Launches X Guide Dual Pulley Chainguide

2012 Truvativ X Guide chainguide device with dual pulley design

New Truvativ X Guide shift guide mounts to ISCG 05 or ISCG03. The difference between this and similar pieces from others is the dual pulley setup behind the chainrings. The pulley wheels are a bit smaller than derailleur pulleys, and somehow the chain just jumps between them.

I asked SRAM’s PR manager Morgan Meredith why two pulleys instead of just one that slides side to side and he said “This way has less noise and less wear and tear and eliminates the possibility of derailment when back pedaling because the pulleys are basically pointed directly at the chainring.”

I tooled around the expo on it and it is indeed pretty quiet. MSRP is $TBD and it should be available from August.

The shift guide was mounted up behind their new “all mountain” 2×10 chainrings with 22/36 gearing. They also offer 24/38, which is aimed at the 29er crowd, and they’re available for X0 and X9 as a complete crankset or an upgrade by swapping out the spider and rings on your current crankset. They get a special front derailleur with shorter cage, too, in X0 or X7 trim available in all the popular mounting options.

UPDATE: It’ll also available in a BB mount.

Another rebranded MRP guide. Cool…

The industry needs to get ISCG mounts on every damn bike. Dammit!

Absolutely agree with Steve ^

Guys, I need your help :)

“The shift guide was mounted up behind their new “all mountain” 2×10 chainrings with 22/36 gearing. They also offer 24/38, which is aimed at the 29er crowd,”

I’m a roadie so maybe I don’t understand something here, but what’s the logic behind putting harder gears on a bike with even bigger wheels? Shouldn’t it be the other way roung, e.g. easier gears for bigger wheels and harder ones for a smaller wheel to achieve some kind of balance?

Sorry for this question but I’d just like to know.

mkrs – I don’t think it’s that they put a bigger gear on it, it’s that the granny is smaller to make climbing easier. If you go downhill at all or are really strong, it’s easy to top out and run out of gear on the smaller chainring combos…kind of like hammering down a mountain road on a compact crankset, you simply max out cadence before you max out power. This is also a departure from their 3:2 gear ratios, but the chainrings mentioned here still have the X-Glide ramps, pins and spacing to facilitate shifting just like the original 3:2 gears.

The 22-36 is geared for 29ers to yield more capable ratios for the larger wheel size. The 24-38 would be ideal for a 26″ wheeled trail-bike looking for a reasonable low gear to climb with and a larger gear for descents. Although, you can use them interchangeably as your fitness and terrain allows. Basically, they’re just adding more options so you can choose the ratios that suit your setup.

mkrs, the 24/38 is easier compared to 26/39 which was the standard setup this year I believe. The 22/36 is even smaller for the AM thing.

will this help with chain suck? I don’t see how but it would nice to kill the chainsuck I get with my Superfly 100.
