This front wheel riser helps create a natural riding position when using a bike trainer. When using a bike trainer, the rear wheel is slightly raised off the floor, causing the front of the bike to sit slightly lower than the rear. This riser helps compensate for that.
The square design helps maintain stability during use. Four rubber feet are strategically positioned at each corner to prevent shifting. Strong, durable plastic ensures a long service life. This riser fits various tire sizes (universal). It can be used with road bikes, mountain bikes, and gravel bikes.
