This would be for my "shop" (garage) - not a real shop, but not going in the seat bag either. Is there one you guys like more than Park's CT-3.2?
I've been doing the same thing, although I use a Park CT-2 to break the chain. I've found the links seem to be more reliable and consistent than the various different pin methods out there.I've been using a Park CT 3 for a number of years, issue free. I just use it to break chains, using a link to make them whole. I've used it on 10 and 11 Campagnolo chains and on chains for 5 and 6 speed drivetrains.
I think that the most important thing to consider is a tool large enough to handle easily while doing the job.
pmf, have you used the Lezyne Campy chain tool and, if so, what do you think of it? I have one but haven't used it yet; when I replaced my Campy chain I chickened out and used a KMC link. The whole peening thing seemed like more art than scienceI really like the Lezyne chain tools. I'd love to have the fancy Campy 11-speed chain tool, but it's in excess of $200. Plus, I like links better than pins. I think the strength of the Campy chain tool is installing pins.
Lezyne Chain Drive Tool - 11 Spd - Bike Tools - Ribble Cycles
I've used it to remove the 11-speed Campy chains, but not to do the pin/peening. The peening process looks almost like doing a rivet. I've had bad luck with pins on Shimano chains and only use links to put a chain back together. I think they're superior to pins. A lot less chance of screwing it up.pmf, have you used the Lezyne Campy chain tool and, if so, what do you think of it?
