Reducing saddle bounce when increasing cadence Trying up my cadence, but noticing a fair bit of saddle bounce.

Few things that could be contributing.


I use toeclips over cleats
saddle height (thou I'm at the sweet spot of full leg extension without strain)


Is there any techniques/exercises to reduce this or am I simply trying to increase my cadence too fast too soon?
It is a matter of both fit (frame-geom, saddle position, stem &amp; cranks), practice, and gearing. 

Everyone has a max RPM after which they start "bouncing" and you'll find this RPM is even lower if you're at a relatively low gear. 

Assuming the bike fits you properly, raising your max RPM is simply a matter of practice. This can't be done at will in one session. It is a motor skill that has to be trained by drills and observed for progress. Informally you can try forcing yourself to ride at lower gears than you're used to. Over time your body kinematics will become more efficient and your form will improve (bouncing will start at higher and higher RPM's).

A cadence of 100 without bouncing is achievable by almost anyone who tries for it. Elites on a track have motionless backsides at cadences of well beyond 150rpm.
