Ya boys from Substance BMX in Glasgow, Scotland are constantly out there doing what they do best in the streets. Today they uploaded the next episode in their 'Substance In The City' series and it's another belter. The guys head to the north of the city and tear up some industrial estate rails, nearly lose Luc's bike in the canal and then finish things up with some pole jammin'. Shout out to our favourite big brother contestant on the purchase of his new motor! Featuring Craig Sime, Greg Layden and Jonny Moffat.
