187 Knee Lock-in recaps are smaller caps than the ones that fit the old Pro version.
Here is how they work:
- C1 Cap will only fit the Pro Derby Pads XS-L and it will also fit the 187 Pro Pad in XS.
- C2 Cap will only fit the Pro Derby Pads XL and it will also fit the 187 Pro Pad S-XL.
Advanced cap design closely contours the foam core and casing, greatly minimizing the gaps between pad and cap. Lock-In™ bar works with strap from pad to securely hold and align cap in correct position.
