If you have hope Evo hubs and need to convert them to boost, there is no better option than the MRP boost adapter kit. Hope also have a boost adapter but it adds the full 10mm to one side of the hub, meaning a complicated process is required to dish the wheel. The MRP adapter adds 5mm on each side and includes a 5mm spaced for the brake rotor, resulting in a perfectly aligned wheel and brake. The hub inserts click securely into the Hope hub (unlike other cheaper hub spacers that will fall out when the axle is removed). The build quality is excellent and worth the price.
Great service. Fair price. Fast shipping. Thanks for keeping Kreitler's products rolling.
I had rollers for many years (30) they worked well but they are getting loud and no resistance. After doing some research I I chose the Kreitler training station, and I went to a smaller roller size. (4" to 3" What a difference, without adding the resistance magnets or the flywheel the resistance has increase and gave me the extra work I need for winter training.
