The Renthal Twinring Rear Sprocket is a long-lasting durable Off-Road sprocket that was developed and tested over the course of 5 years. The unique flat face two piece design keeps weight to a minimum and maximizes durability all while keeping a narrow profile. The outer steel ring is expanded at 200°C and then fitted to the aluminum inner before cooling, this process creates a permanent bond while flat socket set screws prevent lateral movement between the rings.

Renthal chainwheels are chosen by more factory Motocross and Supercross teams than any other brand on the market today. Each sprocket is CNC machined to offer the greatest concentricity and optimum tooth profile for maximum life and durability in the most extreme conditions. Through the CNC machining process, Renthal is able to create an extremely durable and lightweight rear sprocket that reduces revolving unsprung weight and allows maximum power transfer to the rear wheel. The Renthal Twinring Rear Sprocket was designed for the serious MX or Off-Road rider looking for maximum durability and performance.

Features:

  • Each Twinring sprocket that leaves Renthal's engineering facilities are individually CNC machined to the tightest possible tolerances, ensuring an accurate and reliable fit
  • Inner ring of the Twinring is engineered from Ultralight 7075 T6 Aluminium which helps keep weight to a minimum
  • Outer ring is constructed from electroless nickel coated steel which ensures an ultra long service life
  • Mud grooves prevent build up of mud, helping to increase the working life of the sprocket

Elevated T-Shirt
Size: Small, Color: Army Green
Cute top. Material is good quality. I wanted something more detailed than just a regular tee shirt. The neck line and cuffed sleeve gives the top a more elevated look. I ordered the army green. It looks like army green in natrual light, but indoors, the color gives off more of a brownish vibe. I found this runs true to size.

Comfortable Fit without over compression
Size: 38B, Color: Gentle Rose
This is a good post surgical bra. I had a lumpectomy and it gave me enough support without being too tight. It is adjustable in the front and the shoulders. Use the size chart to get your best fit. Soft material. Comfortable enough I wore it 24/7 for a couple days. Only downside is handwashing but I will try the delicate cycle on my machine and air dry always.
