Mirrycle FTW
Useful accessories:
1. Rear-view mirror. The fact I haven't broken any of my four Mirrycles over many months with frequent falls of my bikes says something.
2. Kinekt 2.1 suspension seat-post. Worth every cent.
3. Good pedals. It is the rider's most personal item. I've standardised on CrankBrothers Stamp 1 pedals.
4. Good grips. You cannot lose with Ergon GP3 or GP5
5. Ortlieb panniers with QL 2.1 system (fit any rack). Bike Packer Classic for bigger ones or E-mate for a compact one. If the Bike Packer Classic, it has to come with Ortlieb Commuter Inserts (sold separately)
6. Saddle: it is even more personal choice than the pedals. I'm all for Ergon ST Core Prime.
7. Bell: Knog Oi! (two sizes available, needs to be selected for specific handlebars)
8. Proper lighting, provided the bike has none.
