Renthal Hard Anodised Rear Sprocket 184-520

Great Sprocket for Track

I have used Renthal for years on all my track bikes and I've always found the quality to be superb. They get a bit of a beating on track and are a lightweight yet durable.

Removed after 1400 miles

I like the look and feel but no longevity. Removed after 1400 miles as my chain chewed it up. I do 1000 miles a month for commute so this is definitely not a commuters choice. I ended up putting back my previous steel one until I get a new steel one.

Renthal = good sprockets

I haven't tried this one out yet but I have several sprockets from Renthal, both front and rear and they all work very well. They're light and looks nice. Definitely recommended.

Maximum quality

Hello, product of maximum quality, like everything Renthal, very light, much more than the standard, and at the same time material very hard, as well as steel. I recommend your purchase against any other brand. Sportsbikeshop is a very good store, serious, professional, fast. If you find what you are looking for, the best in the world. In terms of service, SPORTSBIKESHOP for me is better than the majority of recognized stores in Spain. Greetings thank you.

Nicely designed product

It was fast shipping and good care of packing of this product. I like the small detail of the gel insert on the side of the sprocket. (Company logo). Today is going to be fit on the bike.

Renthal Hard Anodised Rear Sprocket 184-520

  • Ultimate combination of strength and lightness
  • Enhanced 7075 T651 aluminium alloy
  • Hard anodised coating
  • 33% lighter than steel sprockets

NOTE The second half of the part number above refers to the pitch

Renthal hard anodised sprockets are specifically designed for road and road racing applications. They feature all the benefits of Renthal off-road aluminium rear sprockets but with increased longevity from the hard anodised process.

Hard anodising is an integral surface coating which significantly increases the hardness and wear resistance of the chainwheel surface. Renthal hard anodised rear sprockets are precision CNC manufactured to extremely high tolerances. The high strength is especially enhanced by using a 7075 T6 aluminium alloy coated in an ultra hardwearing finish for extreme mileage. The rear sprockets computer aided 'Ultra light' design gives the maximum reduction of unsprung weight at the rear wheel, to give maximum power transfer. The Renthal rear sprockets are 33% lighter than steel and the self-cleaning mud grooves prevent dirt build up and help keep the sprocket clean.
