I can see theres a chap in Oz that can service these - but I wondering if theres anyone more local - bought on a whim and the digi display is dead and the calendar adjust is misbehaving.
Dekerf are very very good frames - most certainly in the ‘exotica’ category - one of the very best you can buy, whether steel or titanium however I think any 26” frame will struggle to fetch the asking money.
