If the seat or handlebars on your 1260sc Studio Cycle ever start to slowly lower, dont worry! It is an easy remedy and nothing is broken.
On the mast just below the seat or handlebars you will notice two allen screws, one on each side of the bike. With the silver lock lever up, turn each allen screw evenly on both sides a few turns. You will notice that the more you screw in the allens, the harder it is to lock out the silver lever.
Find your sweet spot that will stop them from lowering when you dont want it to and still be able to lock out the lever.
