i read SRM's instruction carefully and made sure to clean the chain rings before sending it in. afterwards i think i used quite a few dollops of Gojo to get rid of the grease
both units are refurb, and i'm just waiting right now. I've found that i tend to get OCD and make conjectures way too often, and most of the time it's not even necessary and i just wasted time thinking about potential possibilities.anyway, if it's a manufacturing problem i'll bet they'll take care of you. you've had this issue for a little while (and called them about it, no?). i *think* you said you bought the DA SRM new, correct (vs used or refurb)? i
i agree with you about saving money vs spending money (particularly in this case), but what good is a device that doesn't report proper #s ? if someone offered a free power meter but the data was inaccurate, would you take it? if the only choice they offer is for you to pay and you truly can't do it (cross that bridge when you get there), maybe explain that to them, ask them if the same deal will apply in the future, and ask for the crank back so you can at least use it as a crankset until you get the funds for the change.
for the moment, all this stuff is just conjecture and probably unnecessary--just let the company come back to you with their assessment first.
when it comes down to it, i'll probably pay up
