Disc Or Rim For Touring ?
By
23 Apr 2017
i'm considering disc for a touring bike but the more i read about it the more i think 'disc brakes are only suited to off road mountain bikes' eg. heavier gauge forks required, hydraulic brakes blowing out on long descents, hydraulic fluid requiring bleeding from time to time. can you tell me what the mix of touring bikes you supply with rim brakes vs disc brakes ? thanks
Hi,

Pretty much the only bikes we fit with a hydraulic disc brake are our tandems (and even this is usually in addition to a rim brake). We do a few options with cable disc brakes but still 80-90% of the bikes we sell are built with rim brakes, especially the world touring ones.

Thanks.
Ok For Lo-Rider Rack?
By
02 Dec 2016
If using mechanical disc brakes, such as Avid BB7(road), will these forks also allow a low-rider front rack (I use a Blackburn) to be fitted without compromising brakes or rack? Thanks!
Hi,

These forks are designed to be use with discs and low riders at the same time. The lower mount of the rack will normally need to be spaced out to allow it to fully clear the brake.

Thanks.
