New rig, used for Cobbles Crusher on RGV course.

New sound system blaring out my Spotify rock compilation . ZZ top perked me up for the serpentine climb before the sprint, again sprint was poor compared to my best

PD4, liked it. Far less churning, more consistent power required. I found it slightly harder to get back on the pack once slightly off the back. Also noticed speed dropped more quickly if you tried to coast for micro rests.

Slightly annoying situation ... got the new power pedals, seemed to work well in Jordan .. but haven't been able to fit them to the Roubaix ... can't get the old pedals off (well, thankfully the LBS managed to get the drive side off, but not the left side). So just had to order a new R8000 left side crank arm! Due next weekend, so hopefully I'll be able to use them properly locally ... will be interesting to see what power I need to get up some of the hills around here.

Saying that though, I'm struggling at the moment in the cold air ... and having to come off the 'good' asthma drugs as they were causing too many side effects. So my asthma is not great. Hopefully will improve once the weather warms up.

When I sent my neobike back I had to leave a pedal on as it was a nightmare. #greaseisgood. Surprised your LBS couldn't get them off though!

Be generous with grease when fitting pedals. Future you will thank you.

They broke a tool trying 🤣

That's impressively bad - particularly if they're the ones who fitted the pedal. I'm always quite careful not to overtighten pedals as I don't want to strip the thread in the aluminium cranks. You've also got the issue of dissimilar metals touching which can cause corrosion when in contact with salt water. Large dollop of grease is the best way. Heck - it's the ONLY way :laugh:

Bike shop fitted the pedals originally ... definitely not enough grease applied.

When I fit pedals, I cover the threads in (lots of) copper grease, and just ever so lightly nip them tight. Pedals self tighten by their opposing thread to rotation. There is no reason to fully tighten a pedal.

I've never had a pedal even when on the bike for 5+ years not come undone.

I prefer to use a longer lever to apply torque rather than hitting a short lever with a dead blow hammer.

Some pedals are Allen keyed for fitting, which is fine but try and get those with a larger socket, less chance of rounding the Allen key. Those with conventional flats, use a narrow, but proper spanner, not the cheap bicycle pressed spanners

Some of the power meter pedals (e.g. Garmin Vector 2 & 3) do specify a torque, but how many people have a torque wrench that fits on a spanner?
I know they exist, but they're pretty niche.

You could get 'crows foot' spanner heads for your torque wrench

There is an additional leverage so this formula needs to be used to work out actual torque

Or just nip them ;)
