Adding a thin layer of gel along the top of our Topo saddle elevates it to something that works on any type of road surface, particularly if it's uneven. We're all huge fans of the Topo for mountain biking due to its svelte, low-profile nature and excellent relief-to-support ratio, but the addition of gel makes it also great for gravel and touring bikes. And, because we want every ride to be a joy, we offer 2 patterned options for your riding pleasure.
