hello every one again .
im swopping my wheels on my nc23 for nc29 ones
what i would like to know is
1. what do i need .
2. what do i need to do .
any help will be great many thanks

u need everthing for the rear...disc,cushdrive and sprocket
u need to file the 3 casting lugs off the rear brake caliper for easy fitment if you turn the mount over you will see what i mean...u dont have to...but its easier if u do
front is a straight swap...altho the 23's front wheel is a smidge lighter...but that wont matter unless your racing

thank you .. just got a rear wheel today £25 . need front and the rest of the bits for the rear . im not puting them on the bike untill the winter rebuild (power coat + paint ) + need to choose the colours

what size is the standard sprocket as i have a 525 chain and want to fit
a 525 45t sprocket is this posable thanks

Why do you want that size sprocket?
Jesus, you will need a huge chain.#
The 29's have 39 links as standard.
Just take the front to a 14 tooth.

Depends.

15/45 is a ratio of 1 to 3, if it is the ration you are after, you could use a 14/42 set up which will allow a shorter chain (102 links I believe).

Depends on where you are riding. It's all relative, number of links doesn't matter so much, more important is the wheel base you end up with - you have over an inch from one end of the adjuster to the other. If you don't use a longer chain than standar I doubt you will fit the 15/45 and if you do you'll have a short wheel base and be pretty close to hard up against the swingarm on the adjusters. Not good for rough public roads.

Short answer, YEP it's possible but you'll probably need a longer than standard chain. Most chains come with 110 links? (I think?!) which is more than you need.

the reason i want that gearing is i have a 600 engine fitted and thats the gearing i had on the 600 bike before i striped it .
the bike pulls alot better with it . i have 14t 42t at the minute with an 18" rear wheel . when i put the 17" nc29 rear wheel on it will have the same gearing as the stock 600 . but to get the best from it i found that 14t front and 45t rear with 17" rear wheel was the best set up for me . i dont like doing 145mph and dont need to as this is what it dose now . i would like to get to "70mph" very fast . thank you for your coments when i find somewhere that i can get a 45t from i will see about the chain i thought i minght need to get a longer one .

I've got 45T NC29 rears in stock new - few hill climb customers !!

great keep one for me as long as its for 525 fitting chain

a 520p chain will be fine
just change the front sprocket as well
