After last weekends progress and also receiving my 74mm DPR crank in the post this week I was amped to get back out into the man cave and spend a little more spanner time on the oval. The DPR crank is an awesome bit of work. It's a stock 36hp crank that is welded and offset ground to give the extra stroke. It also has counterweights added and is heat treated to stress relieve the crank after the welding process. The end result is a very affordable 74mm crank.
