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 aluminium inner before cooling, this process creates a permanent bond while flat socket set screws prevent lateral movement between the rings.

Renthal sprockets 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 feature Renthal's self-cleaning design, preventing build-up of mud, helping to increase the working life of the sprocket

WIDE Dress Shoes With SUPPORT
Size: 10.5, Color: Brown
I've seen dress shoes and worn dress shoes before, but these are simply the best dress shoes I've ever worn my entire life. 99% of dress shoes have the same problem, they have the thinnest little soles that offer no support. BRUNO MARC HAS SOLVED THE PROBLEM. These dress shoes not only support wide feet like mine who historically have had and still have little support in the market, but Bruno Marc has wide options that fit perfectly, and the support with the thick foam sole is so needed and awesome. I had a pleasant surprise putting these things on and there being some tactile grip enhancers inside the shoe so you can feel the shoes better and get a little tickle / massage while you're at it. These things are dripping with style, easy to wear, and while they might look firm on the outside, on the inside the shoe just has such a nice flexibility and foamy feel, the top where the top of your feet feel the roof of the shoe, it has such perfect ooey gooey support I can't believe it. The outside sole also has this neat tactile feel. The durability looks good and feels good for now.
