Don't know my own strength

I keep snapping brake cables (specifically pulling the pear nipped off) with my aero levers, wondering if anyone has similar experience? Typically happens when commuting and someone pulls in/out suddenly and I stop hard (or try to).

The levers are Tektro RX 4.1 (aero levers) on bull horns bars.

i use magura rt6 aero levers, no pear to snap, problem solved.

Exactly this happened to me last week. I also find that the inner housing somehow manages to push out of the outer, rendering the brakes useless.

Can be pretty unpleasant.

Congrats to you.

Anyone else?

What brand of inners and outers do you use?

I've had the barrel break of twice in the past couple of years. These things aren't going to last forever. I've not just gotten more paranoid about the creaks when breaking as that is the only thing I can tie back to both incidents as possible warnings. I am guessing the strands of the cable were starting to work themselves loose over time until a point where an emergency stop was enough to kill it off.

Here's a few possible reasons for trouble with brake cables. Check that cable is routed so that there isn't a sharp bend right after the brake lever. Make sure the endings of cable housings are properly cut without sharp edges and that you have the end caps where needed. Lubricate the cables inside housings so there's as little friction as possible.

The nipple is pulled clean off the cable, or the cable snaps?

The cable snaps close to where it meets the nipple

Thanks. Had a look and the angles look good. I've put in a new cable with plenty of lube, if it goes again soon I'll remove the levers and check the housing.

Torque wench everything.

Bolt should be at least 7Nm.

Measure back and see what's there.

Or buy my levers: I offer a no-snap guarantee.*
