Designed for long, fast gravel races, Aspero-5 is for those who toe the start line with purpose, and aim to be in the group straightaway. Our engineers like to say, “if it looks fast, it probably is.” It’s a bit tongue-in-cheek, but there’s some truth to it, and Aspero-5 looks fast standing still. The cables are tucked neatly inside the stem and headtube, there’s a hint of a wheel cutout, and all of the tube shapes come from our race-proven library of shapes.

FEATURES:

  • Lightweight Speed: Some might say aero doesn’t matter on a gravel bike, but if you’ve battled a headwind across an open prairie, the thirty-two grams of drag you’ll save with the Áspero-5 come as a welcome respite. Most gravel racing is done without the benefit of a World Tour peloton—or World Tour tactics—and when it’s your nose in the wind all day, it’s nice to know your bike’s shouldering a bit of the load.
  • Two-position Adjustment: Trail—front-wheel response to rider input—is the most critical factor in high-velocity handling. Flipping the two-position "Trail Mixer" to compensate for the difference in circumference between a 650b and 700c tire maintains consistent handling by maintaining consistent trail figures.
  • Multiple Configurations: We designed Aspero with clearance for up to 700c x 40mm tires or 650b x 49mm tires. Of course, there are variables—rim width, tire casing, and tread depth—which will affect final clearance. We (and the International Organization for Standardization, or ISO), always recommend 4mm of clearance between the tire and frame.
  • SRAM Integrated Power: Red and Force builds include Quarq Zero powermeters integrated into the crank. The integration of a powermeter results in better stiffness, lighter weight, and improved accuracy over aftermarket solutions—and the DZero delivers power measurement accurate to +/- 1.5%, even in variable temperatures.

Great Bang for the Buck!
Size: 5.25” Woofer
These R50 Studio Monitors are worth every penny. One could easily spend a heck of a lot more to get less. Have been a pro audio engineer my entire life. These monitors kick out clean, solid bass and accurate highs. Klipsch did a excellent job designing these monitors. Perfect for smail spaces where fidelity is critical. If you wall mount these, make sure you leave at least a 1.5 inch air gap between the back of the monitor and the wall. These units are sweet.

Worth the price
Size: 5.25” Woofer
I had in ceiling front speakers and went with these instead. The front ceilings are now height speakers. Sounds great now.

Great sound. I can turn my stereo up loader than I care to listen to it and notice no distortion.

THE BEST SPEAKERS
Size: Pair, Size: Pair
These speakers are the best sounding bookshelf speakers i ever saw or heard. The sound from them is clear even from a cheap crosley suitcase record player and the bass is just awesome because you can actually hear it and it ties my songs together when i can actually hear the baseline. They work extremely well independent of a separate subwoofer because the bass is very strong! Another point of praise is that the decibel count is very high at 93 which means on very low power they perform loudly. Even on low volume from my Aiyima A07 Premium amplifier, they can be heard throughout my house. They look so cool and appear to be very high quality build and strength. They can be used for whatever you want (provided your amp is compliant) they're super easy to set up because all you do you just attach the sticky rubber feet on the bottoms and the grilles are magnetic for whatever aesthetics youre going for. Definitely worth the money (i bought them on sale for $230) very top notch speakers!

Very good speakers
Size: Pair
The r51ms are used to compliment my klipsch rp500m speakers and a 12 inch subwoofer in a large living room. By placing the r51m speakers to the outside walls , and the rp500m speakers to the interior, closer to the amplifier, and with the subwoofer set on deep bass only at just enough volume to barely compliment the sound, the large living room is more than sufficiently covered with at least true high fi quality sound, if not true budget audiophile sound. My entire 2.1 system is all klipsch. That's how I want it. I am using them with a high powered tube amplifier, so presence and clarity is awesome. Placement is critical. I was initially disappointed until I switched the r51ms to the spread to the outside walls position, and the rp500ms to the interior, closer to the amplifier. The difference was remarkable. The 2 different klipsch speakers, ie one a rp and the other a r series blend together perfectly with no clash whatsoever because of somewhat more refined sound on the rp500m speakers. The rp500m speakers do sound higher end , but they are supposed to, but with the speakers as outer r51m and inner rp500m, and the klipsch subwoofer at deep bass with just a touch of volume the result is sound of such quality that I can honestly say I can be content and satisfied with it. I can say my system is complete, and no further improvement, upgrades are needed. Tower speakers as primaries are not necessary because of the high quality of sound and the high sensitivity of the 4 klipsch bookshelf speakers and klipsch subwoofer. This saves me money during this rapid inflation period of time. I could easily say that what I have sounds more than good enough to be satisfied and content with without any desire to upgrade further at this point. Shipping speed was excellent via Amazon itself, and the box and speakers arrived in handled with care and new condition. I am not disappointed at all now that the r51m speakers are the outside speakers, spread apart from corner wall to wall to compliment the interior placements of my rp500m speakers by klipsch. Im all klipsch here and I love it. 5 stars categorically. As previously stated, I see no need for primary tower speakers, even in a large living room, and that equals high quality sound and savings of money at the same time. I recommend these speakers. They do more than just do sound quality wise.
