Buddy! read your manuals, you struggled taking the non drive arm off, because you never lifted up the safety pin, which is plastic, and there to save your life if your crank arm comes loose!
the 12newton meters torque equals a 12kg force applied on a 10 cm long torx wrench. You can use a hand luggage scale to pull on the wrench just to make it perfect.
Yikes... you need to properly adjust bearing preload with that plastic cap. Too tight (as yours was) and the bearing will not operate smoothly and wear out quickly. Too lose and there will be some play in the NDS crank arm. You must thread the needle inbetween. Park Tools has a great tutorial to help with this.
OK this is how NOT to install a Stages power meter. You should probably make annotations where you advise people to flip that plastic security tab and use a torque wrench. Maybe use some grease inside the crank arm hole, too.
Will a ultegra crank work on a tiagra crankset? reason i ask is because i currently have a tiagra bike and i want to buy a powermeter but am going to upgrade to an ultegra bike in 6 months of so and leave the tiagra as a rain bike.
You need to get a torque wrench and some proper tools if you are going to be working on your own bike. And a bike work stand so you don't have to be on the floor removing crank arm etc, I believe every cyclist should have these tools. Even if you are not a mechanic. The bolts on my bike seat post crank arm etc are always torque to the proper spec no guessing don't want to over tighten or not tighten enough. You can get a torque wrench for reasonable price they not that expensive at all.
Lol! Man before you remove the left crank arm you should unscrew the screws and pick up the plastic protection, then go down easily. And so... You scratched BB's, and destoyed a protect.
Ok so you're 2.5 years into using your Stages PM. How do you like it? Have you seen a noticeable improvement in your power, speed, fitness, etc? Please share. I'm thinking of getting one. Thanks!
Thanks for this video. I just got a PM too and was having issues with the crank not coming until I saw you use the small round tool. I guess I need one of those! :-)
Nice, I am waiting for my Stages Powermeter to come. Hasn't shipped yet, but should be shipping out soon hopefully. How are enjoying riding with power?
I like it so far. I've only put in a couple hundred miles with it, but I'm starting to get a feel for how Watts compare to heart rate. For example, if I keep it below 200W I know that I can eventually recover from a hard effort.
Great, I'm looking forward to being able to work with power after I do my initial FTP testing to get my numbers, then can set my zones to be able to know if I am going too hard or too easy and relate that to my RPE and heart rate as you mentioned. Of course retesting every so often. I recommend reading "Training and Racing with a Power Meter, 2nd Ed.". This is a great book if you are going to train and ride with power. Thanks for the info.
Yes VEGAN Weight, but mostly asthetics (weight is in the range of 10's of grams). If you're not swimming in money, it's probably a good idea to go for 105 version.
I actually wrote to Stages about it and asked. Any Shimano crank will work with a shimano crankset, as long as it is "hollowtech 2 standard". I have no idea of what that last thing is supposed mean.

you didnt pop up the plastic tab the secures the crank arm if the bolts come loose.. so i hope you didn't fuck the crank by forcing it off
@6:56 gives a clear view of it. it is in the channel between the bolts in the centre. you needed to flick up the little plastic piece
theritchieli Yeah, that would have been nice to know beforehand.
You need to get yourself a torque wrench before you do your next video and some grease.
Thanks for the vid! Stages power meter added to my wish list :)

Florin Crisiacu Isn't it 12kg of force applied to the end of 1 meter (100cm) lever?
Swink No, it's 1,2kg with a 100cm lever if you like

not a correct way to remove & install the crank arm.
It was hard to come off because you need to lift the "Safety Clip"

I'm riding with Shimano 105 and my mechanical skills are 10 times that of yours :P
Have fun with the Stages! Buying one soon.
A great video of all the things NOT to do when removing crank arms.
Are the stage products compatible with the mio 505 hc?
Are these factory crank arms that they simply buy and then install their power meter system to?
Yes.
Thanks for this video. I just got a PM too and was having issues with the crank not coming until I saw you use the small round tool. I guess I need one of those! :-)
The small round tool is called a compression tool. Part nbr: TL-FC16

If i buy the PowerMeter for the Shimano 105 and then buy a new bike with ultegra6700 do i need a new PowerMeter???
No, the 105 crank will work perfectly even is the rest is Ultegra. The 105 crank is probably slightly heavier.
oisiaa thx for the quick answer :) but i dont understand why Stages makes differences in the gear. is it just because of the weight?
Yes VEGAN Weight, but mostly asthetics (weight is in the range of 10's of grams). If you're not swimming in money, it's probably a good idea to go for 105 version.
CrY of FuN yes, i bought the shimano 105 version!!!
Looks like this ones a job for the LBS
Buuuuuuurro.
can i put a stages 105 crank arm on ultegra crankset ?
Yes.
what about 105 5700 arm on a ultegra 5800 crankeset ?
Ask stages about it.
i just placed a ultegra 6700 on a ultegra 6800 crank set so i think you can.
I actually wrote to Stages about it and asked. Any Shimano crank will work with a shimano crankset, as long as it is "hollowtech 2 standard". I have no idea of what that last thing is supposed mean.
