I’ve just swapped out the kit from a Ti456 to a Sanderson Blitz mainly because of the On One’s bb height issue, but also because of the cockpit length and the slight insecurity I always felt going down challenging stuff (did everything else A1). I can’t help thinking that the Ti456 was not a mirror image of the steel version, there was something different, beyond the lasck of tyre clearance, that was not an improvement. I think the Ti456 needed a 160 fork to balance it out which I think would have hindered climbing and I wasn’t wanting to go there anyway.
I’m well pleased with the Sanderson. If you search on here you will find a muddled review I did on it and you will find some piccies kindly posted for me by a fella called Paul.
My reservations about the Sanderson were weight (The frame was 5.8lbs and I’ve built it to 29lbs while still retaining stronger weightier parts, and I’m getting used to that.) and speed (but having serviced the rear hub and gotten rid of draggy old bearings and serviced the rear brake and freed up draggy pistons, I’m no longer bitching about that either) and the cable routing (I’ve put in a full cable run to the rear which has sorted that) and I don’t like the bolt on mech hanger (but I can see why they did it).
It ticks every other box I wanted ticked though. It goes up and down better than a 456 and I find it more balanced with a (510 axle/crown, is it?) 140 fork, and it is more forgiving on the rear end.
My experiences with a Pace 303 suggest that the 325.5 would be good but I doubt you will get 2.35 tyres on that…..
….. and the one ride I had on a Transition Transam suggest that was going to be worth putting up with a 30lbs build weight. It was instantly engaging…..but look at the headset (integrated campag) and the rear dropouts (you’ve got to take them out if you get a puncture) before you buy…if you were minded I think it would be worth it.
