I've got a bit of an issue with a few things, hopefully some of you can help my sorry backside.

I've got a hope disc caliper on the front wheel. The two rotors that came with it are slightly different but both too small. They are 165mm in diameter.

Question 1 - How far into the caliper should the rotor go? (only goes half way with this rotor.) the pic below has no rotor attached by the way

Image

Question 2 - I've got two different types of bolt to secure the rotor to the mount and each disc has different holes. One has a tapered hole, the other is totally flat. Which is the norm?

Image

Note: If i use the black bolts on the flat rotor, the wheel will not turn round as the bolts catch on the forks!! The best case scenario at the moment is the tapered bolts on the tapered hole'd rotor. BUT then the pad is only being half warn as the brake zone is half empty.

I'm assuming a need a larger disc (something like 180/190mm?) with tapered holes, and that is 5 bolt. How do i know which bloody one to get? I think the brake is a hope hydro?

Any help is appreciated!!!

thanks

Rich

seems you need a 180mm

i think hope still sell the 5 bolt discs :?

the disc with holes wouldave come with the hope sport , black 2 pot caliper and large lever , pretty sure it was an open system too

looks like you have the hope pro caliper , from memory the only real difference is the lever and its a closed ( lever has a dial and different shape )

the lightning bolt disc came with hopes first 4 pot system but i cant remember what it was called

a side on pic of the caliper could be usefull

email hope , they will say to upgrade to the laest but just tell em you need to know whats what :lol:

this: http://cgi.ebay.co.uk/ws/eBayISAPI.dll? ... 0321695054


looks like it'd do the job.

only problem is if the holes are not tapered, i wont have bolts to fit it if i want the wheel to move round

so many questions....

and pro

but i forgot both types came in both open and closed variety :oops:

maybe someone on here is using a hope disc on hi 5s that can tell you what size disc you need as you might have the wrong size caliper for the disc on that fork
