SOLD OUT!
I just sold my last set of NOS (new old stock)  Shimano 105s and sold the last set of Ultegras about 2 years ago. I haven't seen any new ones for sale, at a price I could turn a profit on, for over a year.

For short road cranks you have a couple of options, shown at right >>>>>>>

$159 W/Shimano 30-42-52 Chainrings.  24, 26 & 28t Inner Rings Available. 		The bad news is that these fine cranks have been out of production since 2006
The good news is that I just found 8 new sets in France, at a price that allows me to sell them, shortened, for only $10 more than they originally sold for, unshortened.

These, and the also discontinued FC-6500 series Ultegras, are the highest quality cranks that can be shortened. Light yet stiff, they are HollowTech, ie. the arms are hollow. However, when shortening the 170 and 175mm versions the new pedal eye misses the hollow section by a good margin.
With the standard chainrings, these are particularly suited for faster riders, (or normal folks with 20" rear wheels).

For the rest of us, $80 will upgrade you to
Salsa 24 & FSA 39/48t Chainrings
 CNC'd from ultra-hard 7075 alloy
(Or $82 for 26-39-48)

Over the years I've sold about 70 of these chainring upgrades and have had nothing but good feedback
 For an additional $11.95 I can install FSA or Problem Solvers "One Key Release" type crank fixing bolts. They allow you to remove your cranks with just an 8mm Allen (hex) key.

About the Shimano 105 crankset
Weight;
With Shimano 30, 52 & 52t Chainrings - 669 grams after shortening. With FSA 24, 39 & 48t Chainrings - 641 grams after shortening.

Q factor; 161mm with Shimano 118.5mm spindle.

BB spindle;These will fit any 118.5mm Shimano Octalink type V-1 spindle; 105, Ultegra or Dura Ace.  (Only 105 triple spindles are still being made.)

If you need a BB spindle - I urge you to support your local bike shop, by buying it from them. (Especially if you will have them install it. :-)

However, if this is not possible, I can provide one for $59.00.

Bolt Circle Diameter (BCD) The middle and outer ring are 130mm BCD, inner is 74mm.

 How Safe Are Shortened Cranks?
Knee Savers should not be used with these cranks. They increase leverage and may overstress the reduced amount of metal around the eye.

"Safely" is a relative term. Modern cranks hopefully have a margin of safety to allow for the occasional 280 lb mountain biker. Shortening will obviously reduce this safety margin, as there will be less aluminum around the pedal eye than before. The shortened 105s are not suitable for large, strong, high mileage riders.  I've shortened at least 200 105s and Ultegras and have not heard of any failures.

Back in the '70s and early '80s road cranks were often smaller around the pedal eye than is common today. Failures were rare, but not unheard of.
Click HERE for examples.

I will shorten a good quality, cold forged crank if it will have at least as much material around the new pedal eye as those older cranks.
