Re: disc brake caliper rubbing against spokes

Thanks again for all your replies, It's a 6-bolt PD-8 hub. I had a bit of a tinker with the calipers last night an it needs more than just an adjustment there. If I move the caliper as far as it can go to clear the spokes it's then bang up against the rotor so it definately needs "something else". I've ordered a rotor spacer as I reckon the suggestion of a rotor spacer then a washer before the fork mount (cheers reohn2) is definately a logical place to start. I've also ordered a caliper mount to try the 180 disc as I have spare rotors from my mtb so that's another fairly easy trial. I did ping off an email to specialized and my local spec lbs to get their take on the 180 rotor as that cautionary note is something i hadn't considered.

[updated] yep, lbs confirmed upgrade to 180 is not a problem and does not affect the warranty, good times !!

Re: disc brake caliper rubbing against spokes

thanks for the replies, as far as i can tell the spokes look correctly braced, and no the pads aren't worn, it's a new bike with only about 400 miles on it.
The caliper is a TRP spyre, Exposure Lights dynamo hub
i'll start with the disc mount shims which sounds like it should do the job
cheers

any thoughts on the 180 disc option? there was noticeable benefit when i moved from a 160 to 180 disc on a mtb which is why my first thought was the same option here?

disc brake caliper rubbing against spokes

hello all, first time on the forum, and i'm looking to see if anyone has encountered the same niggle that i am, and how they may have fixed it.
I've upgraded to a dynamo hub on my specialized awol and found that the brake caliper is now rubbing against the spokes of the front wheel. it's not a huge amount, it's more of an annoyance than a real problem atm.
(i have tried adjusting the caliper position)
As far as i can see I have 3 options;
change the caliper to a less chunky one
rebuild the wheel which may not actually change much and is probably the most expensive option as i've never done it before
switch from a 160 rotor to a 180 rotor which is the option I'm much preferring due to costs and ease but what's anyones thoughts of running a touring bike with 180 discs up front? With the tradition of the awol, most of the weight is up front anyway so it makes sense but i'm new to road orientated bikes running discs, hence the query.
Has anyone else come across a similar issue and are there any other options i may be missing?
thanks for your time
