I have an old set of XT brakes that are IS mount, a 203mm rotor and a shiny new pair of Lyriks with are Post mount...

I may well be being thick here but I can't locate a suitable adaptor. This is the closet that I have found, [url= http://www.chainreactioncycles.com/Models.aspx?ModelID=13744 ]170mm adaptor on CRC[/url]

Any advice greatfully recieved.

Nick

Nick, I went through this with my hope set up. There is no easy or elegant fix with adaptors. Either sell you old xt and buy a new set or buy a new caliper to use with existing lever. Found these on crc which would work.

Not xt but it should work with your levers. You can always sell spare rotor and mount to get some cash back.

Personally I sold old set up and bought new set specific for forks.

MM, I may be wrong but I think thats for the other way round. I found the same, there are plenty of adaptors if you have an IS fork and post caliper but not the other way round.

Thanks for the advice... and yes Mulletus unforuntately thats the wrong way round.

It looks like I may have to upgrade to a new set of brakes then... I was considering that option but havent really got the gold reserves for it at the moment.

Acually, I have access to a workshop. Is there anywhere I could get the required offsets so I could machine up my own?

Cheers
Nick

Giant used to do one

Was for a 164mm rotor (standard caliper went straight onto a 160mm IS fork normally so the caliper was the +4mm bit

So it should let you run a 160mm rotor, post mount fork (are lyriks 160mm direct fit? (or 203mm direct fit?) and standard caliper
Whether or not it will fit around a shimano caliper I don't know but Giant MPH-3 calipers are pretty big

I never bought one but when I was considering a post mount fork I asked my LBS (JeJames Rotherham) 2 years ago they had them in stock. Ring round some Giant dealers and see if they've got nay left (The MPH brake isn't made any more)

Hope (and others) do a +40mm adapter if needed

THanks for all the info James. Is this the giant adaptor you make reference to? [url= http://www.cyclesportsuk.co.uk/product_info.php?products_id=6000 ]Adaptor[/url]

If so it just looks like a post to post adaptor?

I believe the lyrics are 160 direct mounts.

Cheers
Nick
