I'd advise against using this man's service as he is inept and incompetent at servicing motorcycle shocks. I made the mistake of contacting him to service the Ohlins for my 1200gsa before riding it to Ushuaia. I was planning to buy a set of Touratech shocks, but he talked me out of it, saying that I have "perfect shocks as is" and they will last all the way to Argentina.
Sure enough, by the time I reached Colombia, I had a leak. I flew from Bogota to Los Angeles with the shock in my luggage to rebuild it at Brennan's. (He took his sweet time doing so and communicated poorly about it being ready.) After I got back to Colombia, his rebuild only lasted a few hundred miles. I texted him about it, but he said that I "probably have the wrong shock for the ride I'm doing" and then ignored my messages.
It took Ohlins USA headquarters and their tech in Buenos Aires, Leo Segat, to figure out that the shock had a bad ball joint. Despite having the shock in his possession for weeks, with plenty of time to figure out what was wrong with it, this Brennan guy can only talk about how great he is. When push comes to shove, he's all hat, no cattle.
Here I am, writing this review from Bolivia on a leaky shock that now needs to either fly to Buenos Aires for service or be replaced. Thanks, Brennan, you are a total bozo.
TLDR: Don't make the mistake of hiring this guy. Send your Ohlins to the official dealer in North Carolina; it costs the same or a little cheaper read more
