DVO Diamond D1

DVO is probably one of the most recognized suspension companies, that most people have never ridden. Sort of like Lamborghini, everyone knows when they announce a new car, but not that many people will actually ever own one. Lucky for us, DVO’s forks aren’t quite as spendy as those Italian supercars. Their stylish looks and overall finished appearance however, still offer that same elite-level image and lustful desire.
We tested the DVO Diamond D1 for several months last fall and were excited to throw it on a couple of our test bikes. We’d only been able to spend short rides on DVO products at media camps so we were excited to have a long-term test period on one of their forks.
Custom is king and DVO are well aware of mountain biker’s nature to modify whatever they own. For this reason DVO are ahead of the game when it comes to online service, set up techniques and general 411. Long time suspension guru and DVO employee, Ronnie Dilan, AKA Tech-Ron, even has a tuning tips section on DVO’s website. Want to learn about cavitation, digressive vs. progressive damping or setting up your fork for various types of terrain you may encounter during an upcoming road trip? Tech-Ron’s got you covered.
By learning more about your fork, you’ll be able to take advantage of all the adjustability DVO offers. The new Diamond hosts several impressive features inside its redesigned, Boost chassis. The fork is now offered in two crown offsets, two wheel sizes and travel from 140-170mm.
DVO’s site has a great diagram showing their piston technology, which we’ll display here. It highlights the heart of DVO’s system. DVO claims that by tuning the shim stack they can offer everything from suppleness to progression and support. To combat the hydraulic locking sensation experience on orifice damper forks, DVO has custom-designed how the oil will flow through the piston and shims. By using this design, DVO claims their forks can better react to impacts at varying speeds because the oil can flow at the speed at which an impact occurs.
One of our favorite features of DVO’s forks is the OTT (Off The Top) technology. This allows riders to customize the first 70mm of travel with little to zero affect on the rest of the travel’s performance. To make these adjustments you must remove the air from your fork and use a 5mm Allen key. If you’re a light rider who wants a firm fork but get sore hands on washboards, just soften up the initial stroke and keep charging! If you’re heavier, use less OTT for more support. It’s a really nice feature as I suffer from hand fatigue on long descents.
