Typically, a hanger is going to break well before the der is trashed. Its designed that way.

My buddy that munched a pair of Zipps the other week tore a bunch of spokes out of the rear wheel using his derailleur. Changed out the hanger, der was fine.

The Wheels Manufacturing hangers are typically stiffer than stock, so be aware that the 'fuse' in the system just got rated for a higher amperage. IOW the hanger is stiffer and you'll shift better but you also have a greater chance of messing up your derailleur.

YMMV

Back in the day, a buddy snapped his hanger off while we were descending a rough downhill section. We got to the bottom of the mountain and I ended up pulling him about a mile to the parking lot, with him hanging onto my seat post. Thanks for the memory jog.

That's the point where you pull out the chain tool and make a SS out of the bike so he can ride out.

Emergency surgery on mtn bikes can be fun. ...as long as its not your bike!

Damn, that very thing occurred to me but I thought it was too obvious, so there must be some reason it wouldn't work.

Nope. Works great.

BTDT a few times over the years. Primarily before replaceable hangers were invented. Damn sticks!

The timing of the hanger snap was perfect. Happened close to the bottom of the downhill. Coasted out onto pavement, smooth easy tow ride to parking lot. If you ever head to southwest VA, I suggest the trails at Douthat State Park to experience it for yourself, but a SS won't go very far there.

Love it. So all I have to take with me is my chain tool, which is always in my backpack anyway.

Sorta.

Its like triage for people: first do the easiest fix. Lots of times its the hanger. Then move on to the more interesting things like making a SS, using the bottle cage bolts to hold a broken shifter cable in place, etc.

Unfortunately, a stick in the chain and spokes, at the same time, doesn't break the hanger. Ask my MTB partner. He's done it twice.

When is your next trip down here? The Biology trails at Collegedale are turning into a very nice system. Many improvement have been made since they opened last winter.

arggh, telephone and internet went out sunday early AM. just came back...

yesterday, I swapped my 122.5 stock BB for a UN55 110mm, and yup, my math was spot on.

middle ring is exactly halfway between gear 4 and 5 (out of 8), and with the front derailleur readjusted into sanity, it now shifts all gears, and the only ones that make any noise are the crossover 48:26 (both big gears) and 28:13 (both small).

Running in the gears you /should/ be running, the machined alloy chainrings are MUCH quieter than the stock stamped steel ones.

now, if it just stops raining long enough for me to get out and do a 10-15miler as a shakedown.

Not sure.

I haven't been on that trail system, as I only had a couple days, the last time I was down there.

Campy and Shimano have slightly different tapers, so says the late, great Sheldon Brown;

(if you want a good condition 10 spd Campy crank, pm me, we can maybe work something out, I don't have a BB though).
