Adding power meter to so-called "low-end" bike?

I'm talking about a Specialized Tricross elite 2014; so its not really low-end.

Basically I was thinking that I could maybe use a Stages non-drive 105 crank arm and put it on the Tiagra (FC-4600??) crankset. Is this crazy? I don't know much about this part of the bike.

The reason is cost of course :-) And since the Tiagra arm is hollow I don't think you can glue a 4iiii on the Tiagra; I don't think its 'approved' on 4iiii's site either

I mean, I know I'm "not worthy" but I can still benefit from a power meter for training; no matter what the bike is. Doesn't have to be carbon to break a sweat AFAIK

Thanks!

Yes but you can buy one with the Stages glued on it (not hollowed). I'm looking for compatibility..

The power meter is a tool for you to train with not an add on upgrade for the bike. If you fill you need it as a training tool for some reason get it if you think its going to be an upgrade to he bike do not bother.

Can't think of a good reason why having a 105 crank arm on one side of the bike, and a Tiagara on the other side would cause too many problems, however it seems like you'd be better off emailing the Stages people to find out if this would actually work for the power meter part.

Alternatively, as you're willing to spend $699 on a power meter, why not just upgrade to a 105 full crankset along with that for a bit extra?

I started using 'virtual power' on TrainerRoad on indoor rollers. Finally found the metric I was looking for for training!! Extremely useful for pacing, playing with cadence (different cadence, same power for example; or high spin instant power...) etc.

Since this is a completely reversible/transferable mod, it doesn't matter what bike you put it on. Use it on a Denali, transfer it to your Pegoretti. Sounds like fun.

It should swap over just fine. Just make sure you get the same length crank arm. Don't worry about what kind of bike you are on. What would be better: having a nicer bike with the same level of fitness or having the same bike but being a stronger rider?
