Keep dreaming, it's only February
Blackburn makes the Trackblock 3 because stacking old college textbooks or two by fours under your front wheel is just not pro. The Trackblock 3 levels and stabilizes your front wheel as you do a workout on your indoor trainer. It has three slots that are unique to different wheel diameters -- 700c, 650c, and 26in wheels.
You'll be able to thrash yourself in front of the TV on those long winter nights, as the injection molded construction of the Trackblock 3 makes it virtually indestructible.
- Optimized for use with the Blackburn Trakstand Mag series of trainers to keep your bike level; use with other trainers to raise bar height and simulate climbs
- Item #BLB0146

Don't order for use with TacX Flux
This item is OK, and provides the function, just not with TacX Flux. The TacX Flux hub is less than one inch higher than the center of a standard 700X23 wheel and tire. This trainer block's smallest height is considerably taller than what you need, unless you want to simulate a 15% grade.

Keeps your wheel in place. Meant more for a road bike wheel, though.. Wouldnt recommend putting a mountain bike tire on it or it doesn't stay very sturdy. How fancy do you really need to go with a training block? Does its job.

does exactly what it's supposed to
nice to mix it up a little with the variable heights.

Yep, it holds the front wheel.
It does exactly what it is supposed to do. It levels the bike and holds the front wheel vert steady while pounding the peddles.

Used it on the mountain bike to train inside. Need to try it on the road bike, but so far it's been awesome!
