by 'chain length' I of course mean chain stretch, whether it is worn. not number of links.Nice!
Does it deserve a service?
- Check chain length, if too long then replace chain & possibly cassette.
- New cables & hoses.
- Remove BB, steerer tube & seatpost, check tube internals. If ok, generous spray of linseed oil inside the tubes, and close up.
- Fork service, new seals and lubrication.
- Regular clean & polish.
