The Smart Trainer
Service Specialists

We’re an independent service centre dedicated entirely to indoor cycling smart trainers. Unlike general bike shops, every tool, every bearing, and every part we stock is purpose-selected for trainer repair.

Our CNC-machined replacement shafts and pulleys are manufactured to exact tolerances, and we use only premium NSK and Enduro bearings in every service. The result is a trainer that performs like new — or better.

“Brilliant service. Sent my Kickr V5 in with a grinding noise and had it back within 3 days running smoother than when I first bought it. The new bearings are noticeably quieter.”

“Couldn't find a replacement flywheel shaft anywhere until I found STSC. CNC-machined part fitted perfectly and my Neo is back to full power. Highly recommend for Tacx owners.”
