Have to laugh... if I had more money, I'd definitely put this on my second bike. 700 for SRM is cheap!

I think 700 for the most tried & tested pm on the market is a fair price also!
Although I will consider all 'reasonable' offers, you may be lucky or unlucky depending what mood I'm :P

Amen to that G.

This would look nice on a retro build, just need black hoods and bartape to ensure the PCV doesn't look out of place :lol:

Power meter is something need to me so please excuse my rather silly question:

Is it universally fit any road bike? I have a Apollo Arctec R that runs on BB30.

Is the cables usually run internally in the tube or?

I assume the power meter itself has a battery? What is the life expectancy I will get out of this one? Is battery replaceable?

All questions I asked myself when I bought this :)

The bottom Bracket is a Hollowtech 2 type, which is for standard English thread 68mm frames, however there are adapters to allow the use of these type cranks on Bb30 frames such as the one shown below
http://www.enduroforkseals.com/id286.html

I've never actually noticed anyone elses cabling so I'm not sure how people do it, you can do it internally if you like but external is fine

Not sure exactly on the life expectancy , it was replaced about a year and a half ago and has been unused for a bigger part of that

The battery is 'meant to be sent to SRM' to get changed, however if you know how to solder it's a really quick fix and the batteries are pretty cheap from memory, I think under $50
I've changed the screen in my iPhone and switches in Pioneer CDJ's without prior experience and the SRM is by far the easiest to do from what I've seen online
(Of course you void the warranty by doing this but that has long expired )
There are plenty of guides on how to replace batteries, such as the one here

Hope this answers your questions :)

Also for those on Strava, it's possible to sync your SRM data so everyone can see your awesome power output when you smash some KOMs

For what it's worth, if you're going to use this in a BB30 bike, then if you can use the Praxis works bb30/hollowtech converter/BB, because it is far, far FAR better than any of the standard adaptors.
FAR better.

Also, I believe in principal they can be routed internally, but I am told the cable heads are too big for most normal internal routing holes.
