You’ve been on the ZCoaster for over a year now. Can you credit it with any specific advancements in your riding?
The ZCoaster is seriously incredible. I am not sure that if I rode any other freecoaster I would still be riding it. I love the ability to be able to coast backward without pedaling but I also love being able to use pedal pressure for certain set ups and in certain situations. It is really nice being able to choose how I want to use the hub and it really opens a lot of doors for me. The ZCoaster made it possible for me to learn so many grind-to-180-to-fakie-to-grind combos that come naturally with riding a freecoaster which is awesome, but the most important part for me is that it did not make me lose any tricks. I can still tailtap-to-barspin a quarter pipe using pedal pressure or do a smith up-to-tall grind on a ledge to ledge set up. I just see the hub as the ultimate mix between a cassette and a coaster, which is the best thing ever because it opens up more doors. Not to mention the hub is dialed and durable. As long as you have guards on it, it should be able to take whatever abuse you can throw at it. I have been riding one for well over a year now and have had no issues. Still works just as good as the day I got it!
A 48mm stem, shorter dropouts pulling your wheel forward, and short cranks. Your bike seems compact. Intentional?
48mm stems have always been what I have ran. I personally think they look much sleeker being so compact. It also feels really responsive. Like the rest of my bike I try to have it be as responsive as possible. Every time I ride someone else’s bike and they have a longer stem it feels sluggish turning and I am worried about my bars being close to me when they are backward on barspins.
Do you have a formula for what hub guards/style of guards you ride?
I feel like if you run metal pegs you should have metal guards and if you run plastic pegs I want plastic guards. I want the friction level to be as consistent as possible. Whenever I have ran metal guards with plastic pegs they always grind at a different speed and it makes things sort of confusing. One grind will be super fast and if you are the guard the next time it might stick. I love the Madera plastic guards. They fit on the hub perfectly, look great, cover just enough of the hub/spokes, and last quite a while for being made of plastic. I run the front guards for 6-8 months before needing to replace them which is hardly any less time than I would run the metal guards before.
I feel like Profile is one of those tried and true brands devoid of gimmicky stuff, what that said, the Profile Race cranks are a staple of the brand. How long have you been running them?
I have been running the profile 19mm cranks since before I ever rode for the brand. Probably like 10 years or something like that. I love switching parts up on my bike, but for some reason I just never felt the need to change cranks. I like the streamlined look of the classic 19mm cranks and I rarely have issues with them so it doesn’t make sense to change them to me. It’s crazy that the same basic design for these cranks have been around for so long and they are still being ridden today. It truly is a testament to how dialed they are.
To go along with the race cranks, what size and for how long? You’ve been on those shorties for a while, right?
I have been running shorter cranks for like 5 years at this point. I tried some 170 cranks when I first got a 13” rear end, rode them for a week, and my bike got stolen. When I got it replaced I just went with 165mm cranks because that is what I intended on stepping down to in the end anyway. I never regret going to the short cranks, they just feel better for my style of riding. I could never imagine going back to a longer crank.
What are some key things on your bike that are specific to your riding style/make the biggest difference for how you want to ride?
The biggest one is the short rear end. If you are doing technical grind stuff it just makes sense. With the back end shorter you have a shorter wheelbase and it just allows you to more easily manipulate your bike. To go along with that I have 165mm cranks and have been on them for years. It keeps my foot out of the way of my rear pegs—which are close due to the shorter rear end. They also make you feel more centered which is good for spinning and doing manuals, in my opinion. Another one that I couldn’t forget is plastic pegs. I rode the same when I last had metal pegs, but it was extremely limiting. I would come across a spot that I could ride, but I couldn’t really do whatever I wanted on it. With the plastic pegs, if I have enough wax, almost anything is rideable. It’s nice to know that if I find a spot that is a little out of the ordinary in its construction, I can still have a session on it and get technical rather than having to do the one trick that “works” with metal pegs.
This bike is relatively new for you. What’s different about it from the previous bike you were riding?
I was previously riding my signature frame from Mutiny, but after the decision to leave the brand I was just riding the frame painted black. I saw Robbie Morales at the Vans park and we got to talking. He let me know that if I wanted a new bike I could swing by and pick one up. I have always been into what Cult is doing since the beginning and they made a frame that had geometry I was super stoked on so it was perfect. The new frame is a Cult Two Short frame which has a super short 12.5” slammed rear end. I wasn’t sure I was going to be hyped on running it slammed, but after the first time riding it I was so psyched. It feels so responsive and dialed. You can make the bike do what you want it to do, I never really feel like I am along for the ride. If you are into technical riding the back end being that short is something I couldn’t imagine not having now.
