Wondering why you’d want ultra-compact gearing for your gravel bike? Or whether crank arm lengths as short as 145mm will improve your cadence…or aerodynamics?
Now’s your chance to ask Full Speed Ahead anything you want about either, so you can get your offroad adventure bike, gravel race bike, or bikepacking/touring bike ready for its next big ride!
What should you ask them?
Over the past few years, FSA has released exceptionally small gearing and crank options aimed at (mostly) gravel cyclists. Their compact gearing, which they call Micro Compact, also known as Sub-Compact or Ultra-Compact gearing, offers really small chainring combos…including little rings with as few as 30 teeth.
But can you use them on regular road bikes? How small is too small? Which front derailleurs are compatible? What does it do to chain length? What else do you want to know about putting these on your bike?
The extremely short crank arms were launched mainly at the request of their sponsored triathletes, who wanted to keep their pedaling motion closer to their running motion so they could, quite literally, hit the ground running.
