We know extensive product offerings can be confusing. Here at e*thirteen, we make cycling products for everyone from serious gravel racers to casual weekend warriors to adrenalin junkies jumping off small cliffs on two wheels. 

While we do offer some products for use which span across multiple disciplines, our products with more explicit use recommendations are grouped into 3 categories: 

XCX for cross country or gravel riding. Mostly appropriate for hardtails to 120mm travel FS bikes.

TRS for trail riding. Aggressive hardtails to 140mm lightweight FS bikes.

LG1 for all-mountain, enduro, DH and freeride. 140mm and up. 

Base, Plus and Race are simply our designators for the quality level of the product. This is the good, better, best proposition.

Base = Good

Plus = Better

Race = Best

Take our wheels as an example: 

• LG1 DH is our entry level OEM only DH offering with a lower end alloy rim, straight gauge spokes and brass nipples. 
• LG1 DH Plus is our mid level wheel with a high end alloy rim, butted spokes and alloy nipples. 
• LG1 DH Race is our flagship wheelset using a carbon rim, butted spokes and alloy nipples. 

or our TRS and LG1 cranks:

• TRS/LG1 cranks use lower end alloy arms and a heavier 24mm steel spindle
• TRS/LG1 Plus cranks use stronger and lighter high-end alloy arms combined with a 30mm alloy spindle to further add stiffness and save weight.
• TRS/LG1 Race cranks use carbon arms and 30mm alloy spindle for the ultimate in strength and performance.
