Have an FSA Dyna Drive 48/36/26 crankset on which the drive side pedal came loose and destroyed the threads in the crank arm. I cant seem to find that exact set anywhere online, can someone recommend a similar replacement. I've seen SHimaos ranging in price from $30 to $150 and not sure which series would be comparable quality to the one I need to replace.

Thanks

The Acera is the cheapest with replaceable chainrings. $30 and you need a square taper bottom bracket.
The Deore is a modern 2 piece crank and comes with the outboard bottom bracket for $75. That's the one I'd recommend.

I still like square Taper .. Only have 1, (octalink) that is Not.

But I'm commuting and touring , those who need the latest gear to be feeling competitive, racing, Make different choices.





'/,

For ease of use 2 piece/external BB's like the Shimano HT2 system are the simplest to use, no need to work out chain-lines as they are fixed by the manufacturer, nothing wrong with Square Taper or Octalink, but both are old technology as bikes go.

You may be able to helicoil the crank to restore the threads at significantly less cost than a replacement crank. Your LBS may have a helicoil kit; otherwise, the drive side pedal thread is identical to standard spark plug thread, so anyplace that services small engines may also be able to fix it with a helicoil.

Stripping a drive side pedal on those is really punished in the replacement price.

Might be worth a shot

I was thinking about helicoil, (that link was interesting) .

I just got a call back from my dealer. Apparently the original crank was an OEM and not available aftermarket.

They said Trek tech docs list the Shimano Alivio FC-T4010 48/36/26T 175mm as the replacement. Its only $40 bucks so Ill just swap it out.

Its also an Octolink crank so all I would need is the appropriate crank puller to do the job(other than hex's), right? S
