So you want shorter crank arms – now what?
Continued from Are your crank arms too long?
Ok, I have decided that I want to replace the standard 170 MM cranks on my Slipstream with 155 MM cranks more appropriate for my Hobbit legs.
So I Googled and found almost nothing. Looks like the shortest commercial Road and MTB cranks are 165 MM. There are 155 MM and shorter cranks out there but they are BMX cranks and cranks for kid’s bikes. None of those are drilled for a Triple Chain Ring. There is no way I can give up my Triple.
However, I did read in the forums that there are companies in the UK and USA that remachine Cranks to provide shorter crank arms. They will shorten yours if possible or sell you a remachined set. With the current Euro-Dollar exchange rate I am only interested in USA suppliers.
The company in the USA is Biksmith Design & Fabrications.
They have a selection of good crank sets at a range of prices. For what they do the prices seem quite reasonable ($80 to $160 for a set with chainrings).
You can pick road or MTB sets with arm lengths down to 145 MM and several choices at 155 MM. In general they recommend not using Kneesavers with these shortened crank arms. But they do have a set of remachined Salsa Cranks that can be used with Kneesavers.
I haven’t quite decided which set to buy yet, but I am leaning to the Salsa Cranks because my industrially sized feet rum most cranks.
Next Steps in the process are:
1. Find a Bottom Bracket to work with the new cranks
2. Do I need any other hardware for new cranks?
3. Learn how to remove my Shamino HollowTech II cranks
4. Learn how to install the new cranks
5. Learn How to Set Up Front Deraileur with new cranks
This sounds like fun, I’ll post my experiences as I work through this process.
