vector pedals

Amprodude

Used a set of these today on a bike. However I was having trouble with their use. I was going up a hill out of breath 182bpm on the HR monitor and it's reading 30w instead of 300+watts. The watts then went to 0watts and then 20 watts and this was all happening up a hill and I almost out of breath.What is the problem here? Are these garmin vectors gimmicks or what? My stages powermeter never misreads like that.

where they installed correctly?

they obviously haven't been torque'd correctly to 34-40Nm. i have mine a few months and they always show correctly (well, i think its correct!)

Also, I have noticed that whatever ANT+ items you have connected at the time of installation need to be connected when re-calibrating at a later time.

I've been using them for months and no accuracy issues, if you have installed, torqued and calibrating them properly then they will function as expected.

It was working fine on my first ride and saved it. Then I started 2-3 different rides but didnt calibrate it. Could that be the problem?

On the garmin video on YouTube the installer advises to tighten the pedals firmly using a pedal wrench and if you have a torque wrench, then by all means go and tighten it to required specification. By my understanding it isn't a must having a torque wrench but I'm open to correction.

Maybe your just really crap?
Seriously though, most of the examples I've come across have been temperamental as hell with torque. And to answer your question about them being a gimmick? Yes, I think they are. They just don't seem to hold up on Irish roads, I've lost track of how many I've seen being sent off on warranty in the last 3 months even.

Every video put the garmin video suggests that if you dont torque it to the correct torque you wont get accurate or repeatable readings. I think the manual says the same.

They are fussy, no doubt. I accept that, and have not gotten used to when they are telling porkies. I think the flexibility of them between bikes is still worth the messing.

How much do these fancy pedals cost?

i got my Vector S on sale @ rosebikes.com for 623 euro delivered.

Of all the brands I've tried (Powertap, Quarq and SRM being the others) I find them the most frustrating. With my first set I was having to re-torque before every ride and they were not recording power when the should have been. On my second set now but it's really only back-up, on the spare bike or to be transferred to one of the others if its PM is "incapacitated" for any reason

Once torqued correctly they're fine, you also need to take the batteries out for a while after changing bikes with them so they'll re-calculate the installation angles or if you re-torque them

There should be none of that messing around for pedals system that are the bones of a grand. They should be bulletproof for that price.

Maybe I am but even the crappy riders are entitled to use power.

Sure torquing only takes a second, as does popping out the batteries.

i love how my garmin cadence meter (the newer one) just works, head unit finds it and were off.. i know its a different less complex bit of kit to a p-meter but i get amprodudes frustration.. for big bucks you want to just hop on the bike and have it work everytime

Well said Amprodude.

Correct torquing would be where I woukd start from and if that don't fix the readings to within the normal +/- range, I would be following up with point of sale/dealer.

I assume there are no medical factors here? No need to go into if there are. Just saying there can be a physiological reason for lower readings ( which are measured correctly by the PM)

Is was a joke about the 30watt readings mate...:rolleyes:

I will get a torque wrench and torque it correctly. Would I be able to get one of these in a LBS? I had a look this evening at the setup and I noticed one of the black clips that stick into the pedals had fallen out. I noticed when spinning the crank that the cadence was hitting 0 so I knew something wasnt right. I refitted the pedals clipped in the black clips and calibrated and it worked fine again. I will get a torque wrench though to make sure it falls into the required specification.
