SS conversion kits..

James Q

I've been looking at the DMR and Gusset conversion kits, but I notice they say that its only suitable for 8/9 speed hubs but mine is a 7 speed. Is there any way the kits could work with my 7speed rear wheel?

supersonic

Nope. Unless it has a 8/9/10 speed freehub body and running a 4.5mm spacer for your 7 speed cassette.

James Q

ok. Is there any kits that you know of that will fit? And is a tensioner needed?

supersonic

What hub do you have? Is it a screw on type of cogset, or a cassette type?

You still need to work out whether it's a freehub or a freewheel.

I have tried looking online and cant find an answere the rear wheel is a Formula DC27 alloy rear hub but cant find out any where if its a freehub or free wheel?

Have a look:

cooldad

What size is the smallest cog at the back?

James Q

Its a casset type so guessing free hub?

James Q

My current casset is 11-28T

cooldad

That would be make it a freehub, so depends whether it's a 7 or 8(9) speed freehub.
One alternative is leave as is and just don't change gear.

James Q

I'm guessing its a 7 because when I changed the casset on a service there was no spacers evident.

cooldad

You already have a cog (on the cassette), and spacers (the rest of the cogs). You will need a tensioner, which you already have (the mech) so just use the limit screws to hold it on one cog and see if single speed is what you really want.

cooldad

If it is, remove a chainring or two, the shifters, limit the front mech to work as a guide and voila, ghetto SS

James Q

Will do, but this is the direction I want to take. So back on the conversion kits I'm guessing I'm going to have to find one suitable for 7 speed hub.

supersonic

You could make one up using cassette spacers and a cog - it is just the the spacers with the DMR kit are too big.

You will need a tensioner of some sort.

James Q

Im guessing it must be but they seem different sizes.

Yes you can make it work. A2Z ad Mr control supply kits with sperate spacer. Remove 6mm of spacer and add 1.5mm (wheels manufacturing make these) and that is 4.5mm of spacers removed which is what you need to make it fit.

Also the Mr. Control kits come in 14-18T cogs opening the possibility of a tensioner less setup, something I used with sucess in the past.

Everything is possible mostly, if you think around the problem abit.
