The UK company Slick Revolution are now offering for pre-order (available June 2018) an interesting wheel kit for Boosted Boards, to work both with their own large 110mm Rough Stuff Wheels with treads or, usual favorites, the softer 75a ABEC 11s.
The kit is a really good value at £29.99, for the 56-teeth pulleys and belt-covers. The Rough Stuff 87a duro wheels, which come in red and black, are extra at £74.99 (including bearings); although, I don’t know how they will perform against the slightly more expensive ABECs. on vibration and ride. Equally, I need to check the compatibility with existing belts and the torque and speed impact with the new 56t pulleys and 110 wheels, compared to the stock 50t pulleys and 80mm wheels. Different gearing can increase speed, but reduce torque, or visa-versa; personally, I would like to keep the torque and am not bothered about increasing the speed.
UPDATE: I checked with Slick and it works with the existing belts, with the gearing giving it an increase in speed (and decrease in torque).
I have been looking at various wheel-kits, including the excellent Booster Box kit, for the last month. Much as I like the Orangatang (Loaded) Kegels, at 80mm, on the Boosted they don’t give much clearance for the belt guards and we constantly grind them when traveling over our local rough Victorian pavements and roads; running a 110mm wheel would give greater clearance.
