To add stability to the front end of your bike when riding on a trainer, this Elasto Gel Travel Block helps with balance & is a vital accessory to training at home. Made with an Elasto Gel insert & deluxe base, the block creates a level training position by raising the front wheel to the same height as the rear when on the trainer. Overall this will contribute to improving balance, & the Travel Block can be clipped on to the handle of the trainer for simple storage when not in use. A really useful piece of kit.
