I’ve also had the snapped rear gear cable. My right R7000 lever munches a gear cable about every 3000 km though. Adjusting the high limit screw gave me the more palatable choice of the 13t sprocket for the ride home rather than the 11t. [Edit: I now carry a spare gear cable as well. ]
Another time I crashed & the bike fell on the rear derailleur, thankfully only bending but not breaking the hanger. I adjusted the limit screws & the cable tension screw to get home with a few choices of gears.
Bike multitool other than tire repair? Its been a few years, but I still carry one. Sometimes I pull it out at work to make a minor tightening rather than use the full size hexes I have stored in a desk drawer.
Key-chain mounted Gerber dime helped me on my commute/errand ride today to take the license plates off my now totaled SUV.
Better to have and not need, than to need and not have. Or something like that.
On one ride, someone had a pedal fall off. ‘Does anyone have a pedal wrench?’. Um, no… Left my truing stand at home too, sorry.
You can have too much stuff, and some people have issues like I had once: Every popular size of allen key, and no torx! Why does SRAM do torx? Just to piss us off?
Chain breaker is of limited use, IMO. But if you have one, make sure it’s for the chain you are riding. Older multi-tools with chain breaks are likely not going to work well for some chains.
I use the Silca Italian Multi-tool, and it came with their little carry pouch when I bought it as a package deal. The Italian Swiss Army Knife actually, and they don’t sell the little pack I use any longer. If you need anything more than that, you really need to see a bike mechanic or aid station?
You can carry too many tools. Someone was carrying a Park Tool DAG for a tour. Too much?
On group/club rides, I usually have a repair stand and a pump, and some other tools, spare tubes, etc.
I say yes. A pair of pliers will probablydo the job on the roadside.
Speaking of too much, my training buddy years ago quipped me for carrying a square taper crank extractor in my saddle bag. But at the time I had no cycling-specific tools besides what was in my saddlebag, & carrying it on the bike meant I at least knew where it was.
I’m interested to know what this repair stand looks like. Obviously it’s not going to be what I’m picturing in my mind which is a 5’ high, 15 lb workshop stand, strapped to your back like a quiver & causing all manner of aches when it slides around.
I get that Torx has more surface to bite into that is supposed to save the fastener end, but how many times have people used one bit that is just about the right size and risked messed up bolt heads? Will we have to have more multiples of Torx sizes eventually? And the sizes are sometimes so close, and yet could be so disastrous for tight bolt heads if they don’t have the exact size bits. /rant
Ah, for tinkering at the start/end of a ride. That makes sense. I thought initially you were talking about some fancy little stand that can be fastened underneath a top tube that I didn’t know about.
In the computer biz, I had a vendor tech freakout because I had security Torx bits. Really. ‘Dude, you can buy them damn near everywhere now! Amazon, and even the big box stores! Where have you been?’ (It was a few about 8 years ago, but I had several sets of them. Yeah, they weren’t as secure as they thought! One set even has security Allen bits, in case I run into them (Wiha has the best bit sets))
You can use torx keys on allen bolts and the question should be the other way around, why are we still using allen bolts when we have superior torx with less danger of stripping
I had a bike with a FSA BB30, also 8mm allen bolt that needed routine re-tightening. In my case, the torque required (>50) to do the job was a lot of wear & tear on the multi tool. I would usually just tolerate the ticking until I got back to the car, where my big Park shop grade wrench was.
Had to repair a couple of snapped chains - never my own, always fellow cyclists. It was a previous chain snap that made me start carrying one. I often get roped into using the hex keys to help people adjust their bikes.
Was recently in the market for a stem. Anything with Torx (like Zipp) was out from the start. No good reason for it. And I’m not carrying another tool because of it.
I don’t need to try, I’ve used both in either in a pinch. A Torx is objectively weaker fastener and driver than a hex. This isn’t something that is up for debate.
