The Voodoo Wanga is a great bike for the price, Not sure if there are any left in stock.

I have a Lezyne Femto also, very good. Taken a lot of abuse and used in very wet and up to -10 conditions and still works fine.

And the Blackburn Mars 3.0, Can also take a lot of abuse but is brighter than the Femto but not as stylish lol.

The works shower is where my boss told me to keep my bike lol.

Were fitted about 30 years ago and don’t think they’ve been used/cleaned for about 20.

Very old fashioned steels works… i.e it’s a shit hole lol.

Personally I wouldn’t dare let rain/mud etc stop a ride, Especially somewhere as good as Hebden.

Natural trails, Natural weather. Do it.
