Hello again.
Just an update for anyone following this thread. I've been scratching my head and generally going round in circles looking at potential bikes! Decided early on that I wanted something from a UK outfit, which limited the field of players.
I discounted the Sonder Frontier because it uses an odd rear hub standard that would make upgrading/replacing wheels difficult. Not too sure that a rigid aluminium fork would be too comfortable either.
Discounted the Ramin 3+ because, although it looks like a well spec'd and capable machine, it was perhaps a bit too "bikepacky" for my overall requirements.
Discounted the Whyte 629 'cos I think it's just too long and slack to be comfortable over any distance. I now realise 'trail bike' means 'trail centre bike' and I have no real interest in visiting such places.
Started looking at frames with a view to building something up. The Stooge looked like a contender for a while - a very versatile (and pretty) steel frame and rigid fork combo that would pretty much take any size wheel you could think of. None in stock at the moment though and probably a bit too much for my budget, meaning I'd have to compromise elsewhere (wheelset probably). Then remembered Sanderson from years back and found out they currently do a steel 29er frame at a decent price, with similar 'progressive' (ie. a bit of a hoot) geometry to the Frontier. Not much info available though. Think it'll take up to a 2.4" tyre but waiting to hear if it'll take 650b+ . Then chanced upon the Onza Payoff. Another steel 29er frame, similar geometry and will definitely take 650b+. Frame gets very favourable reviews and currently available with 10% discount direct from Onza. Also available in virtually the same shade of blue as my old Grifter. (Full build is available in a lovely sparkly orange, but not as frame only) I'm think I'm about to click buy....
Now, do I keep my old Cove Stiffee, sell it, or dismantle it and sell the bits!?
Apologies for rambling.
