Flexzion Bike Trainer Front Wheel Block, Indoor Bicycle Riser Support

Works perfectly. I use it for both road and gravel bikes. Tire groove is about 2” or 5 cm.

I thought the Flexion Bike Trainer Front Wheel Block was too inexpensive to be very good. I was wrong. It is a great addition to my trainer set-up. My bike sits in a Wahoo Kickr Core 2 trainer after having removed my rear wheel. The wheel block goes under the front tire but on top of my Wahoo Kickr floor mat. It perfectly stabilizes my front tire. I couldn’t be more pleased with how well it works! I highly recommend it.

Perfect wheel block to level my bock for the rear wheel trainer i have. No sliding around and after 2 years it still looks brand new.

This works very well. I am pleased with this product.

It is a cup for the front tire...

Not sure why the manufacturers don't include this product with the trainers. This is a must if you are using a Wahoo indoor trainer. Great product, it fits perfectly, doesn't move while riding.

Great

Did not give 1.5" of rise like advertised. Im not sure why I believed the listing but it is actually 1" for road bikes. Otherwise, it does what it says.

Tutto ok, come previsto.

Ok

Marche super bien ! Solide

I have used this to steady my front wheel when on my indoor trainer. Works perfectly

I picked up this front wheel support block to pair with my indoor bike trainer, and it’s one of those small accessories that surprisingly makes the setup feel more professional. The block lifts the front wheel just enough so the bike sits level instead of tilted forward, which makes longer indoor sessions feel more natural. It also helps keep the bike steady under the handlebars instead of wobbling around when I get out of the saddle. The design is straightforward — solid molded plastic with a rubber-textured base that grips the floor and prevents slipping even when I’m pedaling hard. It fits a wide range of tyre widths (from fairly narrow road tyres up to fairly chunky mountain bike tyres), so I didn’t have to worry about compatibility with my hybrid. There aren’t any bells and whistles to speak of because it’s basically a wedge of plastic, but that’s also part of the appeal: no setup, no adjustments, just place it under the wheel and you’re good to go. The only minor quibble is that if your floor is super smooth, a small mat underneath can help it stay put even better. All in all, a solid supportive block that makes indoor trainer rides more comfortable and stable — especially useful once you start pushing yourself on longer workouts.
