Story time folks.
I just had this happen last weekend in Moab. I was on the Gold Bar Rim trail and took a VERY silly little tumble. Not a scratch on me - but my handlebar hit the ground at JUST the right angle to SNAP my Hayes Brake housing in half (front brakes no less). The brake handle completely flopping loose on the ground, 100% unusable! The resevoir was luckily in-tact.
So there I was halfway through this LONG 28 mile ride that finishes with the Portal Trail...a quite gnarly technical decent and NO front brake. I'd be TOAST without my front brake. One of the crew of 13 with us whips out some zip ties...5 minutes of tweaking later - VOILA! Presto! It worked well enough that I hardly noticed the rest of the ride.
Look closely...the zip ties worked so well it's hard to see the break...
Any other amazing trailside "McGuyver" fixes out there?
