Having had the standard shimano leaking calliper issue, I decided to get some Hope RX4 calipers to replace the Shimano ones.
On fitting, I can’t get the rear calliper central on the disc due to the hole spacing on the calliper ie it won’t go far enough over.
I’m fitting the calliper using a Shimano IS to postmount adaptor, wheels are hope RS4 with center lock disc mounts and Shimano discs. The Shimano caliper was dead center on the adaptor with no issues.
Any suggestions?
Give Hope a call. I have found them to be very helpful.
I tried hope, but in the end the box of bits came to my aid with an older adaptor that worked. I now have the classic clash with the front caliper on the post mount adaptor so hunting for a solution to that.

iirc an upside down rear 180 adaptor and lots of filing 🙂
Thanks for that suggestion, I have one of those. Any other options will be considered as well....
Hope say they're not compatible but where there is a will there is a way. Won't be offering it for any other customers though, it's a right pita!
Woo hoo! My obsessive retention of objects and memory gives me a win. Hayes 160mm IS to postmount adaptor works. Found on the wife’s commuter bike. Thanks for the suggestions.

Just created an account to say thanks to Carbis for the tip on the Hayes 160mm IS adapter. The RX4 now fits perfectly on my fork. I thought there was no chance of finding an adapter that worked when I saw how far out my old Avid adapter was with the RX4 (the part of the adapter between the two IS bolts needs to be really cut back for the caliper's upper cylinder to fit), and the Hayes has this. Found a cheap new-old-stock OEM one on eBay.
Anyone have any idea why Hope aren't supporting IS adapters with these? They just say they aren't compatible with IS mounts.
Stealing an adaptor of the wife’s commuter, I hope her life policy is upto date .. ;0)
hope calipers need hope adaptors or a file and time
