Can I upgrade to Ergon GP3 Grips, Schwalbe Marathon Racer Tires and Box Three Brakes, on the Liberte, of which I have two? Thanks all.

Hello Mindfrog There are a couple of considerations to take into account when choosing grips. Most grips are sold as a pair. Most pairs are designed for either a twist or grip style shifter OR the trigger type shifter. The twist style grips are shorter than the trigger style. On all ZiZZO Bikes, we use a "hybrid" setup: Short on the right and long on the left (because there is no left side shifter. Because grips are sold in pairs of one style or the other, you may need to purchase both grip lengths. The tires, on the other hand, should pose no problems ;-) With regards to the brakes, we cannot make any specific recommendations, but all ZiZZO Bikes do use industry standard parts and sizing. If the brake you are looking for match the stock brakes specifications, then you should not have any difficulties with these brakes. Please let us know if you have any other questions. Tony
