Due to the popularity of the SS+, e*thirteen decided to continue designing budget oriented, but still race-worthy chain guides. e*thirteen created the new LS1+ chain guide by combining heavy trickle-down design with smart materials and engineering. This design was shaped by hundreds of hours of engineering and analysis. To help keep price down, e*thirteen used a durable stamped steel back plate.
After over a year's worth of testing off and on the World Cup circuit, the LS1+ has proved to be just as strong and reliable as the LG1+ retention system, and at 245 grams, it is lighter than most other high-end aluminum chainguides on the market at almost half the price.
Notable features of the LS1+ are:
The full LS1+ chain guide system retails for $90, or $60 for the bare bones system.
