Decreasing power reported by Rally XC200

Yes, I agree. I’ve been riding with power since 2002 and you can tell if there’s a major problem. I’ve owned Powertaps, Quark, these XC200’s. I just got the 4iiii dual, but I think I like a simple spider based PM like Quark. What are you using now?

Thanks JP

For me, it really boiled down to installing the pedals at 34-35 Nm. In the past year, I have swapped them multiple times between a trainer bike, a road bike, and a gravel bike, always installing them with a torque wrench. The power numbers were always correct. I find it a bit hard though, that you need a proper tool for the pedals to work. Especially that one can't use a hex key for installation. I ended up buying a special crow foot extension to be able to properly install them with a torque wrench.

So when it comes to power numbers, I cannot complain. The pedals seem very reliable and I never experienced any dropouts.

I do have a different problem with XC200: squeaking. I cannot eliminate the annoying squeak coming from the right pedal. It doesn't matter which side I'm clipped in. It doesn't matter which shoes I use (tried 3 different pairs of Shimanos and one Giro). It doesn't matter whether I use Shimano or Garmin cleats. It's making my life miserable, especially during climbs when I try to focus on breathing and putting out power. Garmin exchanged my pedals already twice but I might switch to a crank-based power meter just to eliminate the annoying squeak.

Thank you for the reply. I do use a torque wrench. I guess some just have this issue.  Yes, my right pedal squeaks too. The cleats are loose in the horizontal plane. When Pulling horizontally at 6 o’clock and pushing horizontally at the 12 o’clock you can feel the cleat move or slide a bit, it will also “click” a bit. That’s what’s causing the squeak I think. Garmin sent me new cleats but it didn’t change anything.  I have the 4iiii dual because I’m somehow interested in the L/R info. They have mixed reviews. I’ll let you know how it goes so you don’t waste money. I think in the end, I’ll be back on a Quark.  

I also have that squeaking, spray on lube fixed it. Re-apply when the squeaking returns.

Has this improved at all, in the past year? I've just opened a box of Rally XC200 and (having read the posts here) I am having reservations already!

In spite of my experience, and everyone else here, I would say go for it. Based on the sheer volume of pedals sold, it’s probably just a case of a few bad ones here and there. If they were all bad, these posts would be never ending, filled with hundreds and hundreds of problems from hundreds of hundreds of people.  

Go for it! Maybe yours won't squeak. For me, the squeaking was unbearable and I decided to finally return the pedals.

Full refund? 

Yes, I got a full refund from the shop.
