Wahoo Core, these are the best mid range smart trainers, if you can find one it will be $900 + tax + shipping.
Got a TACX for an early Christmas present, wife says only one trainer allowed in the garage. Here's your chance to get a Core for 20% off, it even comes with an Ultegra 11 speed 11/32 cassette, I might have a 10 speed too. Upgrade your inside ride for only $720, price is firm and you pick it up.
