It will probably cost nearly as much to shorten as a new chain set.

The last set Mike Burrows did for me a year or so ago cost £28 inc return postage...

My apologies for inserting a rude word into my previous posting. Any Ian Dury fan can re-insert it. I blame it all on my Grandmother who taught me to swear at a tender age.

"Spinning" is easier on shorter cranks as you have less distance to move your feet or flex your legs.
I.E. The longer the throw the slower the RPM.
Picture an ice skater spinning, to spin faster they pull their arms and legs tight into their body making a smaller circle and to slow down throw their arms and leg out away from their body making a larger circle.

Suntour make some 152 triple cranks, they appear to be "8s" which should work on 9s chain. Look for the "JR" in the model number. Not expensive.

My knees like 155mm cranks, though the Thorn and Alligt ones I have don't seem to be available at the moment.
Built f' comfort.
