Once upon a time, most stems had quills that inserted into the steerer tube. The stems were made from forged aluminum. Cinelli, 3TTT and others offered them. They were attractive and relatively lightweight, and stem failures were unheard of. Many of these old stems are still ridden daily, decades after they were made.
Today, most stems are for Aheadsets and clamp directly to the steerer tube. The first ones usually were welded or CNC-machined. Today, most are forged as well, and they no longer break as often as they used to when this technology was still new. They are a little lighter, but the most important reason for the switch is that the fork makers no longer have to thread the steerer tubes. The threads had to match the frame head tube, which required a different fork for each frame size. With threadless forks, one size fits all.
One manufacturer has continued to make forged aluminum quill stems during this time: Nitto in Japan. Their top-of-the-line model was called “Pearl” until recently. For some reason, Nitto cannot use the name “Pearl” any longer, so now they are simply called “NP”. I imagine this being short for “Nitto Pearl”. What hasn’t changed are the high quality and the beautiful finish. The classic Italian stems never looked this nice.
Another reason to like the Nitto “NP” is that it can be equipped with the Grand Bois/Compass decaleur – the only decaleur with tolerances tight enough that your bag doesn’t jump out when you ride on bumpy roads.
The decaleur is modeled on an old Alex Singer design. It replaces the bar clamp bolt of the stem, and it comes with all the hardware needed to install it. We also offer Grand Bois wonderful fillet-brazed steel stems (which are also made by Nitto), but they are expensive, so you better know your stem length before ordering one. The Nitto Pearl is a great and more affordable solution to getting a reliable decaleur.
The decaleur is a quick release for your handlebar bag. It keeps the bag away from the bars, so you can use all hand positions. And when you leave your bike, you simply pull the bag upwards and take it with you. You still need a rack to support the bag, as the decaleur only serves to stabilize it at the top. Rack and decaleur combined weigh less than most bag attachments that only attach to the handlebars, plus, it puts the bag low over the front wheel, so your bike handles better.
The Grand Bois/Compass decaleur has proven itself very durable. After having seen too many decaleurs that failed, usually far from home in the middle of long rides, we are glad to offer a solution that works reliably.
Compass Bicycles now offers the Nitto “NP” stem in lengths between 80 and 120 mm, as well as the matching decaleurs. Click here for more information.
