Saris Climbing Riser Block Black, One Size

Add a bit of variety to your training session with this climbing riser block that lets you choose your own adventure in terms of level of difficulty. This riser block offers a unique design that transforms your at-home workout into a challenging climbing session. Saris designed this product for use with any rear wheel-mounted trainer, and you can even stack two blocks to simulate climbing workouts. Raise your front wheel as high as 3. 1in off the ground with one block, or as low as 2. 1in for a steady cooldown.
