Mandatory Service Bulletins
2014 - 2017 LEFTY HYBRID (1.0), LEFTY 2.0, SUPERMAX, OLAF
Solo Air Superseded By 2Spring System
Subject:
All Lefty Hybrid (1.0), Lefty 2.0, SuperMax and Olaf forks on model year 2014-2016 Cannondale bicycles, and model year 2017 Cannondale bicycles that do not contain the decal depicted in the image above, contain an air spring system called Solo Air. Certain Solo Air systems have exhibited inconsistent performance in managing the exchange of air between the negative and positive air chambers. If this happens, travel, ride height and/or spring rate can be affected, resulting in an unusual or inconsistent spring feel.
Remedy:
Cannondale has designed an improved air spring system called “2Spring”, that can be retrofitted to replace all Solo Air (both Wave Spring and Coil Upgrade) assemblies, kits and maintenance parts. Cannondale builds world-class bicycles, components and parts for riders who demand the highest levels of performance, and is issuing this mandatory service bulletin to ensure all Solo Air systems are upgraded to 2Spring. In addition to improved air chamber management, 2Spring moves more freely at the top of the travel, giving the rider increased traction and reduced feedback. Installation of the 2Spring kit can be done at an authorized Cannondale Dealer. Solo Air parts will no longer be supported and will be replaced with 2Spring assemblies, kits and parts.
Contact:
If you have any questions about this Mandatory Service Bulletin, please visit your local Cannondale dealer or contact Cannondale.
Affected Models:
Cannondale will provide 2Spring upgrades to all Lefty forks that have wave spring or coil upgrade Solo Air systems installed. This includes Lefty forks from model year 2014-2017, except for 2017 forks with the 2Spring decal located on the front of the Lefty fork, 15mm above the lower collar. The image below should be used as a guide to determine if your Lefty fork is affected.
Consumer Actions to Take:
- Use the identi cation guide below to determine if your fork is eligible for a 2Spring upgrade.
- If your fork is eligible, bring it to your local Cannondale dealer and they will facilitate installation of a 2Spring upgrade in your Lefty fork.
