WTB: Spinervals

Currently own: 16.0 - Aerobase Builder, 5.0 Tough Love, 13.0 Mental Toughness

Looking to add a few more for winter time trainer rides.

Not sure if I want to add Basebuilders, Sprint work, Big Gear work, etc.

Would like to know who is looking to sell, which ones, and price.

Thank you.
