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 >>>>>>>
155mm Triple Road Cranksets
$89 to $149 Depending on Chainrings
EbayUsed, and occasionally new, Octalink 105s and Ultegras show up almost daily on Ebay. You can set up a Saved Search string to alert you anytime some are put up for auction.
(fc-5504, fc-5505, fc-6503) for triples or (fc-5501, fc-5502, fc-6500) for doubles. FC-5500 and FC-5503 are not safe to shorten.
In your My Ebay - Saved Searches click on "More actions" and select "Edit Email Options". Click the box marked "Email me daily when new items match my search" and Save.
If you win a set at auction, or find them online from another source, you can have them sent directly to me for shortening.

| 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
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.

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