Zona To Monty Conversion, What New Bits?

Recommended Posts

20"

OK after my zip has been well and truly battered (but still not broken :S ) I've decided I want to get a monty. Now I know Ill need a new bb because my current one has....complications but I was thinking what else will I have to change?

I know Ill need:

snail cams

BB - What size? (see below)

Rear hub maybe? ( " )

Im running a profile rear cassette so will that fit? I seem to remember last time it did. Also what width bb would be good for it? im currently on 128mm gigapipe which i dont like with GU cranks, no bashring

Any thing else I've missed please point out :)

Thanks

You will need a new rear hub as the Montys have a 106mm spacing.

At the cost of significant loss in durability, you will be able to run a Profile by bending away the rear triangle. You might want to have it machined to fit the frame.

The 128mm bb is fine, at least it was on my bike. No problems with the chain line.

Another thing is if you're getting a Monty frame, you might as well get the right stem to go with it. This would either be a 221Ti (if you're rich) or a 221Pr if you have any common sense (which after looking at your profile pic I think you have). Personally I'd also get the 221 bars and have them extended to about 710mm. They have a great geometry although they are a bit narrow.

If you're going to run the Profile without machining it down, drop me a PM because there are a few things you can do to stop the frame from cracking.

Edit: if you're gettnig a Ti you will have no problems with steerer length, the head tube is ridiculously short and the headset goes inside it. A Pr should be similar to the Zona.

having changed from zona to pr to zona

you won't need a new hub the profile fits perfectly but you need to run the snail cams on the outside.

you can get away with a 118 bb with tensiles a bashring and a freewheel you may have steerer tube issues if you've cut the forks down i need 2 10mm spacers on my forks with the zona and none on the monty.
