Touratech parts bought from anywhere other than Touratech UK will always be cheaper, regardless of exchange rate. Even if the euro reaches parity with the pound (which is highly unlikely), a lever bought from OTR will still be �12 cheaper than from TT UK!
I always get anything Touratech from
here and they sell the whole catalogue - it's all about 35-40% cheaper and they charge less for delivery from Germany than TT do from Swansea!! Work that one out?
