Power Torq v Ultra Torq

[HLaB]

Im about to build a bike with campagnolo, am I right in thinking that a Power Torq crank needs a special tool whereas a Ultra Torq one doesn't?

Also would an 11sp campagnolo crankset and front derailleur work with my 10 speed shifters?

Thanks,

HLaB

The Ultra torque crank has a central bolt that holds it together and theoretically needs a special tool to tighten it, I used a 10mm allen key with a ring spanner slid onto the arm to tighten the Centaur one on my Campagnolo equipped bike.

The centre bolt is too far in to allow the allen key to be used conventionally but sliding a 10mm spanner onto the long section allows enough force to be applied to tighten the bolt.

Power Torque needs no special tools to install. Removing it is a different matter...

I install Ultra Torque with the long end of an allen key, tightened with a spanner.

PT removal = nightmare

Yes.

The only special tool you need with UT is a bearing puller (if you ever want to change bearings).

Cheers folks, I went ahead and ordered a chorus 11sp chainset and I needed a new rear mech too so ordered the matching rear mech, hopefully it'll work with my 10spd shifters. I ran 8sp shifters with a 9sp dérailleur and 8sp cassette before no problem with just adjusting the limit screws, so hopefully this will be the same and I can upgrade the shifters at a later date.

If it's 2015 chorus then you may have issues as the pull ratio changed and only 2015 and onwards shifters will work with 2015 dérailleurs. They are not backward compatible.

Sounds like the next purchase will be new shifters

But when you do get those, oh what a group set you will have.

Everything is a 2015 11sp except the cassette and shifters. I'm not actually bothered about 11 sp, I was just going upgrade them if I ever sell the bike but I'll guess I'll have to do that sooner (upgrade not sell, I no been able to bear that with any bike so far)

Doh, realised just after I posted I need an 11sp chain too :-)
