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, P-DENT 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.

The dimple is back!

P-DENT, 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. P-DENT 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 P-DENT system the bar effectively wraps around the steerer tube allowing for a shorter stem down to 20mm in length.


P-DENT 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.

P-DENT, 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.

PhotoThe 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.

Also a 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 P-DENT system is available now to preorder at a $50.00 early-bird discount. Delivery is expected in March 2018.
