after my old Carlton porteur was written off by a rather careless driver I have been on hunt for a solid old frame and fork that would be suitable for taking a beating on porteur duty.
I came across an old tsunoda (Japanese cycle company) grand prix, it has lots of fork rake and ideal head angle with great tyre and mudguard clearance, this all adds up to it being an ideal candidate, its not as lightweight as the old Carlton but that doesn't matter .
