Buying a left crank arm only and not the whole crankset

f_rederik

Having just taken delivery of a Kona Paddy Wagon (single speed) to use as a winter workhorsee for my commute, I am having some issues with the threads in the left crank arm.

I suspect I might have damaged the threads having changed around the pedals a few times.

Does anyone know where I can get the left crank arm only? Don't want to buy a new crankset unless I really have to.

The crankset is the FSA Tempo (City).

Any clues?

(Very chuffed with the bike so far, by the way, but then again my commute is mainly flat ;-))

Damaging threads when whipping pedals in & out is easily done even if you're very careful as I know to my cost to the tune of £50 for a Sugino Messenger chainset. It might be worth looking at velosolo or charlie the bike monger for a cheap SS chainset if you can't find a LH crank.

I completely destroyed the thread in the right crank on my bike on Monday- overtightened the clipless pedal I'd just put it in and 8 miles later the thread was completely bare. Mine was an FSA Omega Mega Exo Chainset, couldn't find a right crank by itself so replaced the whole chainset. Perfect excuse for a bit of an upgrade too though, replaced the BB whilst I was at it

Have you priced up getting the thread Heli-coiled at your nearest engineering company or garage?

There is an answer to wreaked threads. Find a friendly engineering prototype workshop and ask them to install a thread insert. They will machine out the thread and install the insert. Make sure they install the correct hand of thread.
