Hydraulic brake upgrade for Hog's Back Wiggler

This product is an add-on to the Hog's Back Wiggler only. Other models are not straightforward to switch to hydraulic, sorry. 

You can choose between SRAM Guide T (100$) or SRAM Level (50$) hydraulic brakes and levers instead of BB7 mechanicals. Hydraulics are more complicated to maintain than mechanicals, but some people prefer them.

The SRAM Guide T caliper is a four-pistons whereas the SRAM Level is a two-pistons.
