Title: Upgrading braking system
Post by: steeo on May 14, 2014, 06:00:49 PM

I have a Specialized Rockhopper with standard centre pull brakes and am looking at upgrading to disc's front and rear.
The wheels and frame are set up for disc's so would it be better to go cable or hydraulic ???
Is Avid a good make ???

Thanks

You can run 160 m disc/rotors without adaptors, anything bigger will require adaptors.

Thanks to Nigel for the brakes.

Finally got the adapters and disc's and the front fit perfectly but the rear is a different story.

The adapter when fitted is rubbing off the brake disc now do I grind the tabs on the frame as there is
about 2mm before it is flush with the bracket or do I grind the adapter ???

Can I put a washer between the frame and the wheel hub to space the disc away from the frame ???

I am only throwing out idea's here so if the above idea's are stupid please go easy on me  ;D ;D ;D

I saw someone with a similar problem recently, after much head scratching it turned out the adapter was the wrong way round, worth a try to see if you have same issue

1st thing I tried but either way I put it, it still hits the disc.

Picture shows the bits on the frame I was looking to grind off to make a little space.

Pic 2 shows how tight things are. Silver line on the LHS is the disc, block in the middle is the adapter and the blue on the RHS
is the bike frame. (bike upside down at the time of taking the 2nd picture)

Are you sure you have the right adaptor ? You know there is post mount and international standard ? I think you might have the wrong adaptor for the rear one

I have the 51mm International Standard setup on the front and the rear of the bike.
Below is a picture of the adapter that I got except in 160mm and fitted the front perfectly
but the rear is tight.

I like bikes
