GOLDfren began manufacturing sintered disc brake pads for a wide range of off-road and road motorcycles in 1991, nearly three decades on from their first motorcycle brake pads GOLDfren has become one of the largest aftermarket manufacturers in the motorcycle brake disc pad industry. Their development of next-generation products has kept them at the technological forefront of Sintered Friction Braking providing you with confidence in the performance, durability and reliability of your brakes.

K5 Series:

The K5 sintered compound is optimal for off-road motorcycles and ATVs. It is recommended for riders who demand great off-road stopping power and brake pad durability when riding on tough off-road terrains. The K5 series is designed for low abrasive interaction with the rotor, long life and self-cleaning capabilities necessary in off-road riding conditions. Friction materials contain metal-ceramic with a sophisticated bronze-graphite and full-metal mixture formulation with fine friction particles to achieve optimal friction properties.

Features:

  • High static friction coefficient
  • Good abrasive resistance
  • Self-cleaning capability
  • Low abrasive interaction with the brake rotor material
  • Up to 3 times longer operational life compared to organic and Kevlar composite materials

Application:

  • Developed specifically for off-road motorcycles & ATVs
  • Can be used on both front and rear brakes
  • Could be used on the rear brake of road racing motorcycles

Operating Parameters:

  • Specific pressure: 2.0 Mpa
  • Sliding velocity: 20 m/s
  • Constant maximum temp: 500°C
  • Short time maximum temp: 750°C
  • Counter-surfaces: steel disks

What is a sintered brake pad?

GOLDfren only manufacturers sintered brake pads that contain metal-ceramic and ceramic-carbon friction materials, these materials allow for less brake dust and a quieter braking experience. Sintered brake pads are made by fusing together metallic particles under high temperature and pressure which enhances friction properties and pad life, resulting in longer life and stronger braking. Sintered brake pads experience no brake fade when operating at high temperatures and in wet conditions. They also last up to 5 times longer than organic pads and provide additional braking strength. All materials used are environmentally friendly and do not contain any lead, asbestos, fibreglass or formaldehyde.

Reminder: one set of brake pads services one brake disc, if you are servicing multiple discs you will need multiple sets of brake pads.

They’re fantastic!!!!
Size: X-Large, Color: Multicoloured E-(5-pack)
My clothing size is 16/18 and XL. Even though Amazon suggested a size XXL, I ordered my normal XL and they fit perfectly. The fabric for this style is 92% bamboo viscose and is amazingly soft and almost silky feeling. I had ordered a different boy short in this brand but they were 80% bamboo viscose and the fabric was significantly heavier. I returned those and ordered these.

My favorite underwear
Size: Medium, Color: Multicoloured C (5-pack)
Super comfortable!! They are soft and breathable. No pinching, no shifting, and relatively invisible in skirts, pants, and loose dresses. True to size. Excellent quality, holds up well. Only thing is that the wording on the front does come off after a few washes, so you have to differentiate the front from the back of the underwear by how high the seam comes up. I almost exclusively wear this underwear now, I love it!

Incredible Comfort
Size: Large, Color: Multicoloured F (5-pack)
Amazing; I’ll be ordering more. Super soft, lightweight, smooth under clothes, incredible comfort! Best underwear! I ordered these because I’m tired of underwear lines when wearing biker shorts/leggings. Other boy shorts were too long or the bottom hem too thick and both of those issues left lines around my upper leg. THESE are *just right* - perfect length and fit. No panty lines on close fitting pants, comfortable under other pants and dresses, great with jumpsuits, and fit well under slip shorts with dresses. NOTE: These take longer to dry, than similar clothes, in the dryer. No shrinking though. SIZE: I ordered these in size L and they fit perfectly. A little snug when first on but they loosened up. For reference I’m 5’4” tall, about 175#, carry my weight in my hips and backside,wear size L sweats/pajamas/loose pants, size 12 jeans.

Full coverage and full comfort
Size: XX-Large, Color: Multicoloured C (5-pack)
These boyshort underwear are a dream. They’re very soft, very stretchy, and very comfortable. They do not shrink when they’re washed. They’re heavy enough to make you feel like you have something covering you for discretion, but light enough to wear under any type of fabric. I have wide hips and I’m older so I don’t have a tight perky butt anymore. Most underwear tend to either ride up on me or become very uncomfortable. These stay where you put them. And they come all the way up to your waist so that there is no panty line whatsoever. The waist line is soft and comfortably. It does not dig in. They do not ride up and drive you crazy they stay where you put them. I would recommend them to anyone young or old. I have tried so many different styles and materials to find underwear that’s actually comfortable. These are the absolute best I have tried in five years. I just threw all the rest of them out.
