>>1981300>wondering if there's anything lighter that can be trusted.Not really. The peace of mind is worth the weight though in my opinion.
Pic related, the Kryptonite Evolution Mini 5 is probably the best safety-weight compromise, provided your tires are theft-protected with pitlocks or something. That way a mini u-lock is flexible enough. I'm using an Abus Granit X-Plus Mini right now. It's a bit heavier than the Kryptonite at 1200g but beefier and has the better keys and cylinder. The Kryptonite seems to have a lot of quality control issues with the keys.
