Description
P5 Dura-Ace Di2P5 is a contre la montre catalyst. Its made for one thinghelping you go as fast as possible between Point A and Point B. We started with 30 years of aerodynamic expertise, littered with feedback from elite triathletes and Tour de France champions, added more than a few runs in the CFD metaverse, sprinkled in some 3D printed frames to verify what we were seeing in the computer, and out came a faster, more adjustable, and moregaspcomfortable race
P5 is a contre la montre catalyst. It’s made for one thing—helping you go as fast as possible between Point A and Point B. We started with 30 years of aerodynamic expertise, littered with feedback from elite triathletes and Tour de France champions, added more than a few runs in the CFD metaverse, sprinkled in some 3D printed frames to verify what we were seeing in the computer, and out came a faster, more adjustable, and more—gasp—comfortable race machine than ever before.
As built, the new P5 is about 5 watts faster than the old one. A lot of that is in the wheels
there’s not a lot of additional optimization within the bounds of the UCI’s design boxes. But we opened up space in the fork and between the stays to make room for a new generation of wider, faster wheels, exemplified by the Reserve 77/88. Paired with a 29mm tire, these are not only aerodynamically faster, but the larger-volume tire means less rolling resistance as well
FEATURES:
- The new one-piece front end (first pioneered on the S5) is simpler to assemble and adjust, and stack is now adjustable up to 40mm, while the basebar height drops by 10mm to minimize frontal area. The new riser increases tilt adjustability, 0 to 30 degrees, in 5-degree increments.
- The new P5 frame is about a watt faster aerodynamically than the previous model, and has clearance for 34mm tires. That clearance means plenty of room for Reserve's new 77/88 wheelset, and Vittoria's 29mm tire. which saves about 4 watts over the previous Reserve/Vittoria pair for a total system savings of about 5 watts.
- The new armrests and pads on the P5 are wider, taller, and thicker than before. It’s definitely more comfortable, but it’s also more confidence-inspiring. More surface area here leads to better control, which means more time in the most aerodynamic position possible.
- The new fastback seat stay design reduces vertical stiffness by about 22% (while maintaining the lateral stiffness needed for power transfer). The TT position is unforgiving (to say the least), but the new P5 will help you roll into T2 a lot fresher.

Good product.
Color: Bright Silver 2 Pcs, Size: 4.1 Ounces, Color: Bright Silver 2 Pcs, Size: 4.1 Ounces
The measuring jug is resistant, made of stainless steel and with clear marks that make it easier to measure liquids accurately from the inside. The handle is comfortable and the pourer helps to serve without spills that is always a mess at that moment.

Great scale that needs some improvements to be perfect
Color: White, Color: White
Very accurate scale, looks good in white, timer works nicely and I do like the concept of the ratio conversion. Shown in photos with 0 measurement drift over time, even without the silicone mat.
To make this the best scale in the price range, I would change:
- The auto timer function. Timing currently stops if you pick up the brew to swirl; you must completely restart the process if you do happen to pick it up. I would change that to only stop on user input (pressing a button).
- The ratio conversion. Why offer XX.0 precision if you can only change the ratio in whole amounts? I'd suggest offering 0.1 increments, selectable with +/- buttons instead of cycling through.
- The silicone mat is not well affixed and slides around. Kind of useless as-is and I just keep it off. I would wrap the whole thing around the measurement platform, similar to how the Greater Goods scale does it, to really keep it secure.
It's not perfect, but for the price, it's a 4.5/5 for me. Rounding up to 5 since a 4 is considered "bad" by today's online rating standards.

IMO, a filter coffee lovers best scale option on a budget. Solid grade A choice.
Color: Black
I have two other .1mg "coffee" or food scales that I used regular for pour overs. I saw this has 4x display on real time flow rate, g/mg weight, timer, and grounds to water ratio for a solid price and purchased this after reading some reviews. One of my scales has these features, but the workflow on this scale just clicked a ton better for me.
The beep isn't super loud annoying which is a major relief, as I just couldn't keep sound on on my other scale due to that trigger honestly. I tried brew mode immediately and will now only use that when making a pour over. Loved the beep alerting when I finally hit the proper ratio and I like it keeps my final info on screen after the brew for my study. I can actually practice my technique now and not have split attention as much.
This is still compact, but fits a larger carafe well whereas my other scale is a better fit for the espresso machine. The display is clear and buttons have a slight tactile sensation from the print, but are still the capacitive touch based style. I tested it with weights and it is my most accurate scale, it hit the .1g accurately every time or at worst would fluctuate back and forth quickly from the true value (more than enough for me to trust it). It updates and tares from power on fairly fast, it reacts fast enough to touch to not make me pause much.
My nitpicks are that the front clear matte plastic isn't quite uniform flat viewed at an off angle giving it a cheaper look, but that doesn't affect functionality at all and truth is, it really was very affordable for the feature set I feel.
The second nitpick was that the scale's mat does not grip well or fit securely over prompting it to move around easily. For this I had to modify using some rubberized grip tape on the surface of scale underneath the mat itself. Now it doesn't slide from vibration and if any pressure down it doesn't slip. I could have removed it totally, but it is attractive and useful once stabilized. With that modification done, I can fully recommend this scale for filter coffee lovers at any price. Great product, hopefully lasts me a long time.
