We don’t ever leave our bikes out where they can be molested, but if we did this Abus Brooklyn Chain would probably do the job (even if it is heavier than our road bike). The set-up features the following:
- Open 10mm/120 cm hardened steel loop chain
- Fabric sleeve prevents damage to frame and paint job
- 80/TI50 TITALIUM™ Padlock features a solid lock body made from TITALIUM&trade aluminum alloy offering higher security at a super light weight
- Hardened steel shackle with NANO PROTECT™ coating
- High precision 6 pin key cylinder
- Two keys supplied with lock
