187 Pro Derby Knee Pad | Black

187 Pro Derby Knee Pad | Black

Low-profile Pro protection, developed for roller derby.

The 187 Pro Derby Knee brings years of roller derby experience from the rink to your knee, with features tested and refined through input from top derby skaters. It's a lower-profile, less bulky pad with high-level protection, built for roller derby, and it suits rollerskaters and transition skaters who want Pro protection with less bulk.

V-22 Dual Density Foam balances cushion and protection for repeated hard falls, and the Lock-In Core System lets you pull the foam out for washing. A Rapid FLEX Hinge moves through the full range of knee motion, the Fusion Groove Channel helps stop slip-down, and the removable cap is held by the Lock-In Cap System.

Size Guide

Straighten your leg and wrap a soft tape measure around the middle of your knee. 187 measures the circumference of the extended knee. 187 says its chart is a guide based on averages. If you're between sizes or unsure, size up: customers generally do better with the larger size.

The XXL-XXXL size in this listing is 187's 2–3XL. Strap extenders compatible with the Pro Derby Knee are available from 187 for bigger legs. 187 publishes this chart in inches; cm values are converted and rounded.

About 187 Killer Pads

187 Killer Pads started out in an upholstery shop run by a single family, and that sewing-room background still shows in every pad: ballistic nylon, industrial-weight stitching and shapes refined over years of feedback from riders. The Pro Knee is the flagship, and 187 calls it the trusted choice of professional skaters and top athletes worldwide for bowls, vert ramps and heavy sessions.

The pro connections run deep. Keegan Palmer and Steve Caballero have both had signature 187 pads, and Lizzie Armanto worked with 187 on what it calls the first women's pro model pads in skateboard history. On the roller derby side, the Pro Derby Knee was developed with input from top derby skaters, and collabs with Independent Trucks keep the skate culture front and centre. From a first six pack to full Pro gear, it's the pad brand riders trust when they're going big.

FAQs

What size 187 Pro Derby Knee should I get?
Measure around your knee with your leg straight and match it to the chart: XS fits 25–30cm (10–12in) up to 2–3XL at 53–61cm (21–24in). If you're between sizes or unsure, 187 recommends sizing up, as customers generally do better with the larger size.

How do I wash the Pro Derby Knee?
Pull out the foam core. The Lock-In Core System is designed so the foam can be removed and washed. Let the core and the pad casing dry fully before putting them back together.

Pro Derby Knee or Pro Knee?
The Pro Derby Knee is lower profile and less bulky, with a Rapid FLEX Hinge and a groove channel to stop slip-down during derby. The Pro Knee is the heavier-duty option for vert and big bowl skating.

Can I replace the caps?
Yes. The Lock-In Cap System takes 187 Lock-In ReCaps made for the Pro Derby and Pro Knee. Swap them when they wear thin from knee slides and falls.

When should I replace my knee pads?
Replace the caps when they're worn through and the pads when the foam stays flat or the casing and straps are damaged. Compressed foam won't absorb impacts the same way.
