MPC VT Variable Traction Inline Speed Wheels XFirm 100mm 6-Pack

Innovative Design

The VTs employ MPC's Mtech dual-pour construction. That means they have an inner layer of bouncy urethane (similar to the stuff of Super Balls) and an outer layer of hard road-worthy urethane. MPC says this combination makes for a wheel with superior rebound and durability.

Good Looks

The first thing you notice about the VTs is their good looks. The outer layer is made of a transparent tinted urethane (pink, firm; gold, ex firm). Under the outer layer — and clearly visible — is the translucent inner core. Floating (cleverly) between the layers are the black and white letters of the label. Add to that a black spoked hub and you've got a very attractive wheel.

Roll and Feel

The VTs provide excellent roll. Gliding on them, you feel little loss of forward momentum on flat surfaces. They also do a good job of soaking up road vibration.

Hard wheels like these can tire the legs over long distances. But we found the VTs to be quite comfortable when we combined the ex firm with the firm on each skate. They were not as easy on the legs as wheels designed for comfort, like the flexible-hub PC Vanes. But unlike the PC Vanes, the VTs make no compromise when it comes to roll and stability.

Grip

The VTs hold the road very well. We felt confident on tight corners and noticed no slipping when sprinting.

Hub

The VT hub is designed like a jet turbine. The nine spokes slant sidewise like the blades of a fan. MPC says this design cuts wind drag. We can't vouch for that, but we can say that the hubs are strong and not given to flexing.

MPC used to have a reputation for making its hubs too large. But it appears to have corrected this problem. Bearings fit perfectly (not too loose, not too tight) in the hubs of our VTs.
