What did you break today?

Do you ride your hybrid hard? Post pics!

Don't you hate it when this happens?

Nice! I rode home on a slow leak. I noticed my rear tire was soft when I felt it squirm diving into the first of two sharper than 90 corners on the new bikeway in NE DC. When I looked down, I saw the wheel out of true. I thought broken spoke but later found the cracked rim. I made it home without fixing the leak.

Was your tire trashed? If not, did you have a spare tube?

Last Sunday, about 15 miles out and just short of my turnaround point, my seat clamp bolt sheared, leaving me with just a seat post (ouch).
This has happened a couple of times before, so I always carry a spare bolt. Had the seat reattached in just a couple of minutes, but took several times readjusting it to get the seat comfortable again.

I noticed a bit of a wiggle from my rear wheel on the 730 on the way home last night; probably from standing and hammering a couple of hills in an effort to stay ahead of a large tractor towing an implement.

Couldn't see anything wrong it initially so I just nursed it home about 10 miles. Figured I just had a loose spoke or two but to my surprise ALL of the spokes on the non-drive side were baggy??? can't say that I have ever seen that before. It was about dark when I put it in the garage and the LBS is closed on Wednesday so I didn't inspect it further or remove it for that matter.

I need a spare set of 700c rims/tire for that bike...luckily I have a couple of backup bikes.

If something does break on the bike, it's usually just a spoke, and it's always breaks at the hub and not like the OP's rim.

CCrider, ready for the busted seatpost bolt! Good for you. The last time this happened to me, I lost some parts and couldn't use that seatpost again.

Shepp, the non-drive side spokes always have less tension than the drive side spokes because of the dish. This can lead to loosening. It's not too difficult to retention the loose spokes. All you need is a spoke wrench and some patience. A truing stand will make the job much easier, but it's not absolutely necessary. Nice to have backup bikes though, and it's not a bad idea to let the bike shop get your wheel right if you aren't iinterested in doing it yourself.

dynodonn, I have had many rims fail in this way, but I more often wear though the braking surface and get a split in the rim there, where the brake contacts the rim. A friend was *****ing about his rim breaking like the one pictured above because it was on a bike with disc brakes. He thought the rim would last forever because he didn't have rim brakes. "It's a Mavic! WTF!?" He was steamed, but I told him stuff happens, an indestructible rim would weigh 5 lbs. You don't want that.

Chicken dinner would rhyme with winner. I agree that "A sweat." is the best answer to the question. Good one, Danni!

I've had tons of broken spokes, along with bent/broken axles, but so far, nothing like the rim you have pictured. I too have had rims that showed signs of brake wear, but I usually retire them long before they wear down enough to crack.

If you're breaking a lot of spokes, your wheel maybe shot. A skewed frame could cause that too. Busted axles also point to frame alignment issues.

A rim can also split there because of too much air pressure;
I learned that the hard way after splitting the *second* Mavic mtn rim.
Just because a mtn tire specs a certain max pressure, doesn't mean the rim can handle it.

The spoke breakage is over a period of several bikes/wheels, and the bent/broken axles were from carrying too much load weight on freewheel type wheels, and by switching to freehub wheels I've stopped having axle issues.

New rims? I figured air pressure was the force that causes such a split, but assumed significant wear from brake pads had to occur first. I'm putting an iffy wheel on my mountain bike right now to keep me rolling until I get new rims for both bikes. Based on your post, I'm going to inflate to the low end of the recommended psi range.

I switched to freehubs in the 1980's and I don't recall having a bent or broken axle since.

I didn't have any axle issues in my early commuting years, thanks in part that I was commuting on a Schwinn Varsity with it's stout freewheel axles, and later in the early 90's I unknowingly bought a commuter bike with a freehub. It's when I unknowingly replaced the freehub bike with one with a freewheel, with it's hollow axles for QR skewers, that I started having issues. The internet and bike forums are a wealth of information unlike the pre dot. com days of trial and error on one's part.

First time it happened I had a three mile walk back to where I was parked. My LBS wanted $15 to order a new bolt, but the clerk suggested just going to a hardware store. Lowes had it for about $1. Not as strong as the original (lasts 2-3 years instead of 10+ years) but they are cheap. Other than a tube, it's the only spare part I typically carry.

The second rim, (identical replacement of the first), cracked in one month.
The tire was a 1.9" rated at 50-70psi.
I was running them at 70.
The bike was used only on the street.

I don't get it. 70psi is not very high pressure!

I broke my chain today.


Something else bad is going to happen if that cable housing isn't replaced soon. I'll need new cable too, note the duct tape cable end. The cable was too unravelled to get a real cable end on it and too short to make a fresh cut.

You should replace them instead of putting new tires on them.

my week-old rear rack shook itself apart on the ride in to work today. Luckily the bolts that remained held it in place enough for me to ride it to the LBS that installed it and they had it back together in 5 minutes. They said if it happens again or I'm not comfortable, they'll redo it with some loctite but they didn't want to use it if they don't have to in case I want to remove it or run fenders at some point(only one set of eyelets).
