Most peoples saddle height from 1 bike to the next will be out by 2.5mm ... People wont swap crank lengths (me included) however will use different shorts with different thickness padding .

Avoid Stages, i'm currently trying to get a refund. Had a unit that developed the usual battery issues and was sent a new one under warranty. Battery dies on this after one ride, fitted another, two days later whole unit seems dead. Stages want me to bring bike/unit/battery in the house and keep warm. Total waste of time if you want something reliable. Got a set of p1's deliveredd today so will see how they go. Also got a couple of sets of Vectors which I've had issues with but seem ok at present.

Mmmm, made me think a bit more about the Stages option (although talking to a couple of guys at works and they rate them).

Looks like the 4iiii option is a good one and added that they may come up with a 'pro upgrade' version (like they do with the Dura Ace version) in the future so you can get both left and right power readings.

Just trust me on this. Do not do it.

People that rate them have no idea because they've never used a proper one in many cases. Seriously, I could put you in touch with 10 people who have bought these units and had huge issues (not to mention the fundamentally flawed method it uses for giving you power in the first place) - it really REALLY isn't a product you should buy.

I will take your point on board, however, what does that ^^^^^^ refer to? the left hand only side, or something a bit deeper?

The left hand side doubling method that it's based on.

Wouldn't go near Stages ... don't think I know anyone who's on their first one. Most are on their 2nd, 3rd or has given up.

I'd rather work on 'RPE' than Stages ... cheaper and infinitely more reliable!

Thanks for clarifying. For my level of cycling and budget, I'm happy with that approach.

rofl

But for a SMALL amount more you get something that is 10 times better?

Am I mad? Am I? I just cannot fathom people spending 350 quid on something that is LITERALLY all over the internet for how st it is.

Probably the one place I always agree with okgo. For all the accuracy you may as well use HR and save 350 quid. I just don't get it.

Appreciate all comments.

Just measured my bike and I don't have space between my crank arm and frame for the 4iiii option, so that is out whether I wanted it or not. (Bike is a Canyon Ultimate)

My stages (gen2) has been fine smile I don't know anyone who has had any issues with theirs.

Its the pedal based systems amongst the people I ride with that seem to suffer (serious) reliability issues.

Oli Beckingsale had the same to say when I had a chat with him a few weeks back. Apparently they've seen a lot of issues with the P1's but he stood by the stages for most of the Gen2's being good and the customer service being fantastic if it fails. Added bonus, the repair place is only a couple of miles from me.

Still don't know what to do myself though. I'm leaning towards 4iii because of the comments. It's the price point I think gets most people. Sub £400 is easier to swallow and is my personal barrier.

I've got a 4iii. Its my second unit as the first one died suddenly one morning. It took Evans 2 months to get a replacement sorted. I think the delay was more with the UK supplier rather than Evans or 4iii and I think I would have had it sorted in weeks if I had have sent it directly back to 4iii.

The unit itself is fine for what I want to use it for (general training and some pacing on hills and pacing the start of TTs) and I can swap it between bikes in about 5 mins. I personally find that I can go harder and deeper with the power-meter not showing, as the numbers tend to get into my head and I blow up, rather than not knowing how many watts I am putting out and being able to 'hack' it.

Okgo, or anyone else: how do Quarqs cope with Q-rings please? Am I going to end up with useless data if I go down this route?

Echo the above, Stages is a waste of cash in terms of reliability and validity of numbers. Powertap P1s are also rubbish, mine went back to Wiggle for a full refund within the 1st 3 months

Now have a Quarq DZero, but I've not done that many miles on it to make a judgement.

Not sure of latest ones, I know they claim to be able to get rid of any inflation, but I'd be skeptical - testing was done on older units and it was a fairly big chunk if you had the aggressive q rings (from memory)

Also, just use round rings smile

My Stages that failed was G2. The brand new unit they replaced it with last month under warranty was a G2. It lasted one ride!

After reading this little lot, I'll think I'll invest in some new wheels or a smart trainer rather than a power meter
