The rear deflector shield mounts under the rear rack with cable ties. Its extension beyond the rear of the rack is remarkably effective in preventing water and mud from going up your back. If you have no rack, opt for a “rat tail” that mounts on the seat post. To protect your front derailleur from that last bit of muck thrown forward by the rear wheel, mount a simple MTB front fender (no stays) behind the seat tube, attaching its ends to rear fork and chain stays.
A simple forward deflector shield mounted to the underside of the down tube catches most of the road goop thrown upward and rearward by your front wheel. Velcro strips are provided for mounting, but punch a few extra holes if you have a water bottle cage below the down tube (as shown) or add cable ties if the Velcro wears out. A forward deflector doesn’t create the toe overlap that some find is an issue with a front fender.
Those who prefer to tinker have made similar arrangements by cutting and mounting plastic bottles or other lightweight plastic scrap. Be ingenious!
