E13 Crank Installation Instructions

The LG-1 cranks by E Thirteen came out with very high expectations from the downhill community as a whole. This in large part was due to E Thirteen's chainguides that have been one of the best on the market for close to a decade. They aimed to produce a super stiff crank that was both durable and lightweight.

They achieved the stiffness by using a 30mm axle with a German DIN 32711-P3 Polygon Interface. Instead of using teeth or ribbed contact points for the arm/axle interface they used a 3 sided axle that is tapered. It is claimed to be better at distributing the load that other systems currently on the market. 

The arms are forged out of 7050 series aluminum which helps greatly with their overall stiffness. The pedal threads are 14mm deep to give a greater bite on the pedal axle and lower the risk of ripping pedals from crank arms in rocky terrain.

Overall the build quality of the cranks is as good as anything I have seen on Shimano, SRAM mountain bike components. They include all the tools needed to install and service the cranks. They have pretty detailed installation instructions follow them and intallation of the E13 LG1 cranks should be a snap.

This particular set of cranks is about one and a half years old now. They have been installed onto our Banshee Legend and have not been touched. They have been haggle free the whole time and have held up well to rock strikes and harsh landings. E Thirteen nailed the reliability side of the equation with these cranks for sure.

I am about 210 pounds and am fairly strong. The cranks are very stiff. I did not detect any flex in them and feel comfortable saying they are every bit as stiff as Shimano Saints. The aluminum chosen for the arms combined with the massive axle and interface used in the LG1 crank do what they should. Produce a stiff lightweight package that is very reliable.

The crankset as a whole is pretty light. E Thirteen now offers 3 versions The LG1, LG1+ and LG1r they vary in price and weight the LG1r weighs in at 760 Grams including BB which is about 300 grams lighter than Saint! E thirteen managed to make a lightweight Downhill crank that was also durable. Mission accomplished and I would have no problem recommending these cranks to those in the market.
