Bike Check: Acoustic's V2 Steel High Pivot

This bike may look familiar, and for those of you who saw the V1 bike check earlier this year then it is. Zack is the man behind Acoustic bikes, and made a series of rolling changes to his high-pivot trail bike to better suit the nature of use and improve some user comforts. This is one of two V2 bikes he had at the MADE show, both of which feature a whole host of unique components and some lovely paint jobs. The frame is still made in-house in rural Colorado, but now features some 3D-printed steel parts, to allow for better control over the frame's hard-points, and improve the weight and efficiency of construction.
Acoustic V2 Details
• 29" front and rear
• 160mm frame travel, 160mm fork
• 63.5° head angle
• 482mm reach
• 440mm chainstays
• 77° seat tube angle
• 345mm BB height
• Weight: "36ish pounds"

Zach also changed the machining operations for the linkage, now using Ignite Components to handle all things on that front. The bike fittingly comes replete with an Ignite crankset and BB, rounding out the American-made custom bling. That rocker link has a cleverly designed axle connecting the two sides, maintaining stiffness between the two and removing the need for any seatstay bridging.

The anodizing on this build was all done by the ano manager at Industry Nine, who did a great job of tone-matching the whole build, in addition to the classy brushed finish work on a few select components. Certainly bright and assertive, but I'm a fan.

Kinematically, things are fairly similar to the V1 we covered, with the overall weight greatly reduced thanks to the structurally optimized 3D-printed frame components, as well as a suspension switch from coil to air.

 it kills me that writers aren't carrying scales with them when they go out to check out new bikes. like who amongst your readership is going, "no, please don't tell me how much this bike weighs. i want it to be like my wedding night"

 Pretty sure most bike companies wouldn't encourage it. There's a reason you often won't find bike weights even on their websites.

 @lostlunchbox: Kinda like asking a woman how much she weighs.......

 As someone who used to care about the weight of my bikes and tried to keep my bikes in around the 32 lbs mark, I am now on a steel full suspension that weighs in just over 37lbs. At first I thought I’d made a mistake, and I was going to be killing myself on climbs. After over 3 months riding the new bike, I am actually not notidcing any difference in climbs. In fact, I’ve had some of my fastest climbs recently.

I get why people fret over weight, but in the end, 32 lbs vs 37lbs isn’t a game changer.

 @kwl1: It is when it's a large percentage of your weight. If you are the typical overweight North American male sure no big deal but women and normal weight people find it an issue.
  • 8 1
 @kwl1: extra 5lbs added to a 32lb bike is a 15% increase, could totally change the character of a bike (especially if it’s rotating weight)
  • 6 4
 @Henchman21: Maybe women and normal weight people need bikes from the turn of the century. But IMHO nearly everything that makes a modern bike heavier makes the bike safer/faster/more fun*.

Most riders I know love: dropper posts, 2.5 tires, 30mm rims, 800mm bars, larger stanchions, longer travel, rotors that are >=180mm, 4 piston calipers, etc. But hey, if women and normal people want to ride a 100mm travel bike with 19mm wide rims, 2.1 tires, a 22" flat bar and 160mm rotors, or spend 2 to 3 times as much $ to get a modern bike made of lightest most expensive materials so they can save 5 pounds, I say more power to 'em!

*on the downhill part of the ride everyone (who's not an XC racer or a masochists) enjoys most

 @scotteh: But add in your weight as well, including your pack, and then it’s less of an increase. I went from 197lbs total ride weight (bike+pack+weight) to 202 lbs. So, only a 2.5% increase.

 @Henchman21: imagine bragging about being frail.
  • 3 1
 @kwl1: i see your point, but i don't really care about combined weight - it's only the bike i have to pedal and throw around. if rotating weight increases 15%, that's going to be very noticeable in terms of handling and fatigue.

agree that sprung weight isn't a deal breaker though. my bike is 36lbs but fine to pedal cause the wheel/tire combo is relatively light. now if it was still 36lbs, but 3lbs lighter in sprung weight, and 3lbs heavier due to burly rims, DH casings, and inserts, it would suck on the way up...

 somehow, imo a steel bike with coil suspension shouldn't have wireless shifting, or a wireless dropper post.

 I kinda like that it does. To me it says that they stand behind steel as a viable material that is no worse than carbon or aluminum. Like they are trying to make a modern and capable bike, and in their eyes they haven't compromised anywhere. Pretty cool

 It makes perfect sense to me, it weighs more than mechanical drivetrains. A gearbox would have been

 That would be sick. There are way more brands making steel full suspension bikes than people realize.

 No seatstay bridge to contact the seat tube at hard bottom out! Wink
Rad in every dimension, except it needs a gearbox if we're getting picky about the perfect bike.
- Steel
- 160mm F/R
- Geo: Sub-64 HA, 77 HA - perfect!
- Geo: 440 stays for large reach
- Mid-high pivot with protected tensioner
- Standard eyelet mounted shock
- Did I mention Steel
- Coil or air compatible progression
- Made in CO!
- 3d printing used judiciously
- External brake hose routing
- Bottle in main triangle
- Rad anodized colors

 No seatstay bridge + no rocker link bridge = flex

 No chainguide over the idler when the Idler wheel is not concentric to main pivot AND horst link. Thats a recipe for dropped chains. Top shock bushings look overly long. Bent shock mounting bolts are fun!

 "That rocker link has a cleverly designed axle connecting the two sides, maintaining stiffness between the two and removing the need for any seatstay bridging."

I dunno man, my experience tells me that bikes with rear ends like this just aren't laterally stiff, and you would feel the rear wheel "boinging" around when loading and unloading during hard turns. I don't understand how you can move the chainstay CLOSER to the seatstay, forming a smaller triangle, and then make it out of steel with no bridging between the stays and have it be laterally stiff. I am used to riding a carbon frame with a unified rear triangle and I am skeptical about the feel of a frame like this.

 When you colourmatch your whole bike with the tire stickers Big Grin But honestly quite the looker I just be a little afraid I’d quickly make some funky acoustics when those tubes on the head tube go Big Grin

 Should be "Certainly bright and assertive, AND I'm a fan."

The "but" implies it's not good and you're a fan despite that. "And" says it's good and you're a fan because of it.

 @R-M-R: looks like a high pivot privateer 141
  • 1 0
 @darkstar66: So ... the bike that looks most like the Acoustic v2 is the Voodoo Canzo, and the bike that looks most like the Kavenz VHP16 is the Privateer 141? Not that it matters, of course, since kinematics, geometry, stiffness, components, etc. define how a bike rides, not its visual layout, it's just interesting how we perceive things so differently.
  • 1 0
 @R-M-R: oh totally agree, I love the look of the VHP16, it's funny if you squint how some bikes look very similar! Apart from knolly bikes, I can't even think of any other make that looks even slightly like a knolly!

  • 1 0
 @p0rtal00: yes a steel hardtail can come close to a competitive frame weight. Your frame probably weighs 4.5 lbs where an aluminum or carbon frame be 3 lbs. But in a full suspension bike steel make no sense except for the home built garage types who need it as a easy to work and weld material.
