MRP Introduces the 2x Guide
MRP introduces the new 2x guide for 2-chainring MTB cranks (“two-by”). In development for almost two years, the 2x utilizes MRP's patented integrated skid chainring protection and introduces a new patent-pending dual pulley tensioning system.

The 2x is designed to work seamlessly with the new wave of 2x10 drivetrains being specified on many new mountain bikes. These new drivetrains created new challenges to chain management with their unique gear ratios, chain lines, and impact protection requirements. The 2x solves all of these challenges.

To create the 2x guide, MRP began the process of applying their range of technologies and systems to find the optimal solution for 2x10 drivetrains, and through collaboration with SRAM and extensive testing it was decided that the ultimate light weight solution was a chain guide sharing elements of the G2sl, LRP, and XCG products. Notable is the absence of an outer capture ring on the cranksets, relying on the front derailleur and lower pulley assembly for complete chain retention.

MRP’s design goals are driven by the passion to design and produce products that allow riders to just ride – not worrying about chain damage or dropping a chain. The integrated skid protects the chainrings from impacts without the added weight of a full bash ring. The dual pulley tensioning system ensures that the chain is properly tensioned and in the right position, keeping it on the chainring in the roughest conditions. The dual pulleys also reduce drag and noise compared to other designs, ensuring a better riding experience. Finally, the raised top fin profile prevents the chain from dropping to the BB shell.
Features:
- MRP's patented skid (US Patent 7,066,856), removable for those who prioritize weight savings over protection (43g savings)
- Patent-pending dual pulley design provides precise chain engagement while reducing noise and drag
- Raised top fin profile prevents the chain from dropping to the BB shell
- ISCG, ISCG-05, and BB mounting options
- Compatible with 9 and 10 speed drivetrains
- Available in black or white
- Weight: 36-38T w/ skid – 130g (ISCG-05 model), 39-42T w/ skid – 144g (ISCG-05 model)

I would like to use this guide, bb mount, and without the need to upgrade to 2x10, I know it would be optimal, but quite expensive replacing everything, from the cassette to the shifters... =(

We've already got a guide for the impending "micro" revolution too....

9-36 will come for sure... Question is when do they wanna push that? SRAM and Shimano push hard in direction 2x10 so they won't go that way soon. Another player might do that: Hope. That's for sure my next set up. Single chainring forever!

I'm a single ring kinda guy... honestly wanted to see the 9 tooth thing that Monster/Spec boys were playing with pan out, and then someone offer a 9-36 casette and stick with my 32 up front...that would be dialed!

Haha, I dig Noah's solution.

Noah - hahaah! funny, but sad all at the same time. There are bikes out there I really want to ride, but will not just because they feature pressed in BB's and have no ISCG tabs. Boo..
Chris - sweet!!! keep me posted. My twigs cannot push a single ring, so I need 2 x 9/10.

Luc, I'll let you know!
Noah, Thanks! I seriously hope the frame guys figure that out. I run 1x9 with a guide but wouldn't mind getting into a 2x10 setup later on. This guide looks solid for sure!

We've come up with a solution for bikes without ISCG tabs or thread-in BB's....the inclusion of ISCG tabs in their next redesign.

The new distributor will be in Sedona, AZ. Info to come out soon!

ohhhh gotcha. Forgot about Nico M. I would love to try a Commencal AM, but I don't know who will be US distributor (since BTI will probably stop carrying them)

Hey Luc, I was talking about Nico Menard, the engineer from Commencal that designed the bike....he lives in Andorra.
Bjenson, Yes I knew that there wasn't a guide available, but I thought maybe MRP had thought of something else since this is a brand new product.
Oh well I'm not ready for a new bike yet...at least my pocketbook is not, so I'll have plenty of time to wait for the latest and greatest!

hans, no guides will work on bikes with a press fit bb and no tabs. might have to get a dangler!

Nico? did you mean Remy?

Thanks Luc! I thought it was odd that an aluminum frame would miss that. Plus Nico is a super rad guy and a ripper!
