hi there folks..
does anybody have a 1992 or 1993 lower swingarm also seatstay that's not needed so long as it's true and no crack's paint isnt an issue. would be glad of anything as i might have a little project in the pipeline......
-
Might be too late but this guy had a few bike bits for sale including a rather cosmetically tatty 753 frame for £30 (which icludes the bits you need)... he's a top bloke though so it's kosher.

nice one orange! looks like he has excepted £40 for frame and forks off some other dude though.oh and just to be nit picky it's a 1992 cos 93 had cut out on swingarm where pivot bushes are.( soorryyyy) well spotted though cheers..
-
Hmmm...not sure my 753 does. what do you mean by cutout?
-
check the side of the pivots 1992 are flush with plastic caps.. 1993 should slope towards the pivot pinch bolts and if i remember wright have rubber caps? look at my swing arm and compare it..yours is a gen 2..

also where pivot goes through frame 92 had triangle plates and a spacer..93 had just a tube.. bike in your photo looks like a 552
-
here is a close up of mine. By the way, (and sorry for hijacking your thread here), I've noticed that the swingarm on mine tends to move off-centre along the pivot bolt as there is nothing to stop it doing so - is it missing something?

just looking through the original handbook that came with my pro-flex and it says the pivot bolt needs to be 270 inch pounds if you got a torque wrench. the swingarm should fall under its own weight with no wheel or seatstay attached so tighten the pinch bolts according.. other than that you might have some wear and tear and should return to your nearest dealer (lol) as these are meant to be maintenance free so says the handbook..

looks identical to mine except I don't have the black plastic caps... will try and post up some pics at some point.

are those 753 stickers original? as they did the 552 in white most popular in blue though. is that a quill stem 1 1/4" if so i have a black flexstem lying around you can have for nowt also some rigid threaded pro-flex forks but they only fit 16" frame.used them for about 3 month back in 1993 then swapped to vectors.

I assume the stickers are original...I bought it off a guy in Long Eaton a year ago. He'd had it from original. It's not a pure white but pearlescent...
Yes it is 1 1/4 and I would love to have the flexstem - want me to collect or can you post? What's the length of the steerer on the forks as it's a very short headtube on the 753?
cheers
-
hi!
steerer is 100mm between cups with locknut wound on fully. dogbone on flexstem is 105mm from pivot to front of bar. yeah dude come collect im a long eaton lad to but just moved to sawley. not to far from plank & leggit...
