Pacenti Cycle Design’s new bar and stem system enhances rider confidence and safety through increased steering response and better weight distribution.The brain child of Kirk Pacenti, the maverick behind 650b wheels, PDENT is built around a dimple in the handlebar clamp area allowing the bar to more closely wrap around a bicycle’s steering tube. The reduction in stem length is unlike anything else on the market, does not affect stem height, and allows easy headset adjustment while out on the trail. Previously seen in a 32mm incarnation and receiving rave reviews in the mountain bike press as prototypes.
PDENT, which uses a dimple in the center of back of the handlebar allows the use of shorter stems than is afforded by traditional bar and stem systems. This allows for stems down to 20mm in length, unlike anything else on the market. PDENT can do this without adversely effecting stem height and still leave a headset that can be adjusted while out on the trail, without removing bar and stem. The dimple design meets and surpasses ISO standards for safety. The dimple’s location between the clamps of the stem puts it in an area of low stress. ISO standards for strength are exceeded by a generous margin.
With evolution of bike geometry over the last few years to slacker heads angles, longer top tubes, and steeper seat angles, stem lengths have been shrinking at the same time, while the current crop of stems stops at minimum length of 30mm with the PDENT system the bar effectively wraps around the steerer tube allowing for a shorter stem down to 20mm in length.
PDENT continues a trend toward long and low geometry characterized by longer top tubes and shorter stem lengths. Brands such as Mondraker, Geometron, Pole, and Transition to name a few have been pushing the limits using current available stem lengths. PDENT, gives the opportunity to explore new avenues of bike fit, while retaining a low front end and traction over the front wheel. You can also use it to upsize a frame if you’re between bike sizes, and there’s plenty of riders that will just appreciate the nimble handling afforded by the bar and stem combo.
One of the most noticeable effects of the shorter stem in the PDENT system is quicker and more responsive steering. Because hands are brought back and closer to the steering axis, very little input is required to change lines or keep the front wheel tracking as the rider intends through rough and difficult terrain.
Some science for you. With our 25mm stem it takes about 15% less input to effect a 10° directional change at the front wheel when compared to a similar 40mm stem. Multiply that over a few hours of riding, and you're saving a lot of energy.
The options due for release March 2018.
Two carbon fiber bar and stem combination options are available:
1. 15 mm rise with a 25mm stem 2. 25 mm rise with a 25mm stem
Also available to order
1. 20mm stem for those who want to experiment with length.
Both rises of handlebar are contemporary geometry, having a 35 mm clamp diameter with a 5° rise and a 7° sweep. Bars are 800mm wide, and weigh 210g and 220g respectively
(+/ 10g). The CNC 7050 25 mm stem weighs in at 130 g, giving a combined weight of 340g to 350g.

The media is going on how "progressive and new" short stems are but silly enough it is mountainbiking that first introduced these silly long geometries to only later get things straight again. Yes some commuter bikes have longer stems but huge backsweep as well. Road bikes typically have long stems but the curved handlebars bring the hands back too. Road cyclists only put there hands high on the bars for straight steady sections, not for steering tight sections. I'm not commenting on weight aerodynamic shapes they sometimes make...
I can go completely out of context but I just realized there is a place for a flat bar on a long stem. Trials. Yes Ryan Leech typically rides a short stem and Chris Akrigg rides whatever he can get his hands on, but I'm not going to argue with Danny MacAskill. For real trials, he rides long stems.
Right; because moving the handlebars is the bit that tires you out when riding a bike...
