CIB began experimenting with slide blocks in 2012. They saw skaters out creating their own mix and match bits and saw a need for a universal design. They knew we were on to something when the Slider had taken over the skate scene. Now you see blocks of all types on almost every skate! This latest evolution of the CIB Slide Block includes a simple-to-install adapter and features Riedell's signature, proven “twin-fin” design.
 
CIB Slide Blocks come in four sizes and are compatible with popular plates. Best of all, they’re super easy to install without removing plates! There will be a full compatibility list available soon on CIB's website.
Sizes:
S - 60 mm (W) x 45 mm (H) 
M - 75 mm (W) x 50 mm (H)
L - 90 mm (W) x 54 mm (H)
XL - 110 mm (W) x 54 mm (H)
The sliding surface across all sizes is 56 mm
 
If you prefer, use this size guide that is based on a Reactor Neo plate, (which is roughly equivalent to US men's boot size).
