Dude, sorry, I aint no private dick. Bad luck on the theft.
I recommend a ball bearing in the allen hole to prevent opportunists nicking them.
But I'm starting to think they're a bit substandard saddles anyway, swifts, you're best off without that. Why do they pucker so quickly? They seem to need tieing before breaking in. Buy a Team Pro and chop it.
Put my Fizik Arione on the beater but much prefer the Swift TBH - good comfortable short journey saddle. One thing tho - I don't seem to be able to put my saddle back far enough - I'm right on the end of the rails and still it doesn't seem to sit onto my sit bones. Layback seatposts, the merits thereof: discuss.
