    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

    Don't order for use with TacX Flux

    • Familiarity: I returned this product before using it

    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.


    • Familiarity: I've put it through the wringer

    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.

    Yep, it holds the front wheel.

    • Familiarity: I've used it several times

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