Item # SSO000R


Good for riding and good for wrecking, the ultralight Six Six One Rage Knee Guard works equally well pedaling or during an impact. That's something not all knee guards can claim, and it's due to Six Six One's extensive armor expertise.

To start with, Six Six One uses a stretch mesh back and perforated neoprene to allow freedom of movement without annoying bunching -- it also permits cooling air to flow. The Rage Knee Guard is pre-curved and stays in place with hook-and-loop closures to prevent migration. For impact protection, EVA foam sides keep your pedaling smooth and uninterrupted.

And for the kneecap, a hard plastic and internal softcap provide a solid defense against injury. Finally, Six Six One's Rage has a stretch Kevlar outer for durability. The Six Six One Rage Knee Guard comes in one color and sizes Small through X-Large.

  • Hook-and-loop closure
  • Stretch mesh back panel
  • Perforated neoprene sleeve with stretch Kevlar outer
  • EVA foam side panels
  • Hard plastic kneecap covering

Not just for biking

These came in quite handy when we found ourselves in a dark cave with plenty of hands and knees crawling required

Saved my knees

  • Familiarity: I've used it several times

I was using the Gform knee pads and they were to tight. I do have large legs, 17 inch calf and 22 inch around the upper thigh. but the Rage in XL fit perfect! It is hard to find guards for guys who have are a little on the big size not fat but some guys are just bigger naturally, I weigh 195lbs. anyways, these saved my knees I was on a rocky trail out here in AZ, went to fast on a turn and bam! went down scrapped up my arms nothing bad but hit my knees hard, no scratches no bruises! I just got up and continued on.

Hello :) i have a question!! Is this a pair(one left, one right), right?

Responded on

Hi Soyeon,

You'll get a pair. That's one right, one left knee pad. Give us a call if you would like to order, or if you have any other questions!

good pad bad paint

  • Gender: Male
  • Familiarity: I've used it several times

I have used these pads several times so far, some rides lasting for 5 hours. Pads are comfortable once you get the straps adjusted right and have protected me completely in a few spills, nothing too harsh yet. One of the big selling points for me was that these had padding on the inside of the knee where they can come into contact with the frame. A lot of other pads dont have this and you can go home with bruised up knees even though you had on pads. The only complaint I have is that the blue graphic rubs off on my white frame and it can be a pain to get off.

Soft v. hard shell

  • Familiarity: I've used it several times

Background: My first pair of knee guards were 661 Kyle Straight knee guards, which were great--so of course 661 discontinued them. When my Kyle Straights wore out, I bought a pair of Rage knee guards, which supposedly had a plastic insert for knee protection, but I could not detect it, so they seemed like they offered less protection than the Kyle Straights. I used the Rage guards until the velcro wore out, and they protected my knees perfectly in several crashes.

To the present: I ordered the soft version of the Rage knee pads shown here, but when I rapped my knuckles on the front of my knee, it hurt a little(unlike my worn out Rage knee guards). So I decided to order the hard shell version for comparison. I performed the same knuckle rapping test on the front of my knee, and the hard shell version offered the protection I was looking for. Does the hard shell version have any drawbacks? I could tell no difference between the two versions by looking at them, nor could I tell any difference in weight when holding them--they both felt really light. While wearing the guards and flexing my knee to simulate pedaling, I could tell no difference between the two versions. As a result, I was left wondering why anyone would order the soft shell version. I returned the soft shell version.

I've been on three rides with the Rage guards, and I haven't noticed that I am giving anything up in the pedaling department, so unless you can't afford $10 more for the hard shell version, I see no reason to buy the soft shell version.

I can't give these guards 5 stars (yet)because the velcro wore out on my last pair of Rage knee guards, and the guards still had plenty of life left in them. I haven't experienced an crashes yet while wearing my new Rage hard shell guards, so the 4 stars is based on my previous pair of Rage knee guards.
