Trade: My silver Tektro R538 Long Drop Brakes for 'standard' drop one(s)

I'd like to swap my silver Tektro R538 long drop (47-57mm) brake calipers for equivalent quality ones.

These are from my Charge Plug Racer which I have purchased 2 months ago. I have only used the front one, which is in excellent condition. The rear one is brand new unsused.
The 'drop' is too important and doesn't line up with my rims (even at their highest setting, i'm still 5-10mm short) so I really need standard ones. These brakes are ideal for touring bikes/wider tyres (28-35mm).

Realistically, I'm never going to use a rear brake so I could swap the brakeset for a better single front caliper like a good used Ultegra or Dura-Ace. I only run 'thin' tyres, 23mm or less.

Get in touch if you have something!

Wouldn't want to hijack (much) but if you don't get any takers for swaps, I'd maybe offer cash ...

(Based on Ribble price probably though, so not much cash ...)

Hey, I have some virtually new Tiagras that I'll swapwith you?

Cheers,
Gav

Swapped - Good meeting you Gav!
