Compatible with all boat brands.
 
We have developed a high quality bearing wheel that has a reduced radius for better contact with the slide surface reducing the chance of premature and unnecessary wear of the anodisation of the slides.  The design also reduces the torsional rotation of the seat ensuring the seat tracks better at race ratings.
 
If replacing Empacher wheels, all four wheels must be replaced at once as Empacher use a slightly smaller wheel.  All other brands are fine.
