Front Freewheel Middleburns?

you know onza used to do an attachments for putting a front freewheel onto 3piece cranks, well do you think you could have something made to put a front freewheel onto either middleburns or my fsa afterburners?

i've searched the forum and found a little on this topic but nothing that said yes doable or no not...

thoughts?

I don't see why they wouldn't, assuming you had a long enough BB? I mean, mine fit on my mod and I've got but alu stays and tyre clearance for a 2.5" wide tyre :huh:

I thought it was more changing freewheel threaded cranks to having a spider, as opposed to vice versa?

I was told they wouldn't fit too. the BB on the frame is like 83mm wide or something random like that so basically only special BBs fit. tensiles don't bend outwards as much as burns do.

maybe i'm wrong about those 3 pieces but i was sure it was an addapter to fit a freewheel not the other way round.

i can't rmember why i think tensiles dont fit on leesons but i'm sure someone on here had to send clive their cranks so he could build the frame specially so they'd fit, something to do with the amount they curve out from the taper i think and don't forget leesons already use the widest BB's on the market...

the old t-masters came with c-piece cranks and a front freewheel as standard, so im sure supercycles wil be able to sort you out :huh:

cheers

yeah but again that'd mean changing the BB to fit 3 pieces which i can't be arsed with and don't know if its possible anyway...

With regards to converting Middleburn RS7s, I don't *really* see how it could be done. Because it's just got that splined interface where the various spiders sit on, there's virtually no way of getting a freewheel thread on there. The actual bit that sat on the splines would have to be pretty spindly so it could accomodate the internal diameter of the freewheel, plus it'd have to be 15mm deep so the freewheel would fit on. This'd mean there'd be quite a bit of it hanging over the edge, which would stop you being able to put the lockring onto the splined bit, assuming you managed to actually make a splined, threaded attachment for a freewheel.

Anyway, like I said, it was always more that you could fit a spider onto the Onza 3-pieces that had freewheel threads as opposed to the other way round.

Might be out of luck, sorry.

What about ZOO! or Bonz cranks?

Yep they did....

Ive still got the 3 piece crankset of the t-master int garage

from when i had my t-master...

Lee :huh:

what BB did they come with and have you got the front freewhell adapter for them? fancy a swpa or part ex for a 5 arm spider for them so i can see what the FF adapter's like and see if it'll fit my afterburners?

They're squared tapered, aren't they? Are you running square now?

Anyhoo, they don't look too bad. I was half-way tempted before I snaffled up some cheap Tensiles from Andyroo (good luck with the marriage!). Having spoken to Tart, he advised me just to go straight for the Tensiles if I could afford them, but if I was going to buy new and didn't want to spend much, I wouldn't have a problem going for the Echo's. The only problem they had before was the freewheel threads stripping, but they've got a replaceable outer bit now so that should be sorted :huh:

Look pretty fly too...

To Nick - the thread the lockring screws onto on the RS7 crank arms looks to be smaller in diameter than the freewheel threads, if you look at this pic:

Equally, good luck screwing a freewheel onto 2mm of thread, if that's what you were hinting at :huh:

Like I said, I'm almost certain that that threaded part has a smaller outer diameter than the inner of a fixed cog, plus I doubt you could fit the cog on there in terms of width, and it'd be well to the side resulting in shit chainline.

so basically i'd be best off going for a set of those echos yes? or are the musclemans as good?

Tom why on earth do you want ffw? you've already got one on the back lol, surely it wont make any difference to your current setup? oh and musclemans are poo lol

i want a smaller front ring/bash because i think leesons look awful with a big ring and bash so when its time to buy new bits i'd like to either get a tiny front ring and a rear cassette hub or a front freewheel and a small rear cog...

i might look into getting a 6speed profile and making my leeson comp legal and then getting a pair of echo cranks and an 18/16t front cog :huh:
