Awesome road, after Goginan throttle back, the road aint as much fun, plus watch out for Mr Plod in Capel Bangor.
An exceptional stretch of road just make sure you ride it on a weekday as theres too many holidaymakers on a weekend i did it on a wednesday and a saturday and the difference is very noticeable
I live in worcester and travel this route often as an IT engineer. If you want a good day of execeptional riding you need to do the whole worcester/rayader/llangurig/Aberystwyth A44 run. the rest of which is already on this site. M5 j7 to finish it's just about 100 miles.
Devil's bridge on the nearby A4120 is a popular haunt with bikers
Quite fast and flowing through some nice valleys (so there's quite a few changes in elevation), visibility is mostly very good because of the incline/decline so it is mostly easy to see what's happening ahead.
