UPDATE:

Thanks again, guys. Last week I was able to pour 1960W into the machine and it was really steady.



So, being that we are never satisfied...

My SRM track cranks are just sitting on my track bike and won't be used until April or May when the season is about to begin. I want to put them on this thing. They use the Octalink BB.

The SRM records data at a faster rate and sooner than the PowerTap. With the PowerTap I miss the first few seconds of the effort.

I called Cycleops and they said that the BB in the unit is a 113x68 ISIS and uses that big steel combined crank and chainring thing. I have a 109.5 Dura Ace BB, but I think that will throw the chainline off.

So, what are my Octalink options? I've only seen 109.5mm. Are there longer ones? Anybody got a part number for something longer?

Thanks!
