Mavic Aksium 11 speed trainer wheel with new Schwalbe trainer tire, good Shimano 105 11-32 cassette, ANT+ speed sensor, and skewer. If you are still using a not-so-smart trainer and want a dedicated trainer wheel that doesn't shed rubber all over your workout room, this is what you are looking for. Add an ANT+ USB adapter for your computer and you'll have what you'll need for Zwift. $100 for everything. If you don't need the cassette, $75 for the wheel, tire, sensor, and skewer.
Inno INA391 fork lock rooftop bike rack. This is designed for vehicles with factory crossbars, but it can work with aftermarket crossbars as well. Comes with one key for the lock. $75.
Thanks,
Chris
