Blingy bike information alert! Right now, Chico’s personal Paul Part Engineering, identified for its machining wizardry, and for manufacturing lovely elements for bicycles since 1989, introduced their new, restricted 7/8″ (22.2mm) Boxcar Stem.
Based on Paul Parts, “7/8″ handlebars appear to draw probably the most abusive riders on the market”. in order that they took their already in style Boxcar stem, and “beefed it up even additional”. The brand new stems, as with all of their Boxcar stems, are made utilizing 2024 alloy as a result of it has a better fatigue and yield power than 6061.
Paul Parts states that they like to let the operate and materials properties dictate the form of the product. Certain, a few of their merchandise look completely different, however they are saying that’s as a result of they need the product to “work as superior as attainable”.
In order that being mentioned, they made positive that the clamp was additional thick on this restricted model. Additionally they added two extra high-strength, stainless-steel T25 Torx-type faceplate screws. I’ve to confess, it seems tremendous sturdy and utilitarian with the additional faceplate screws. They comprehend it’s overkill, however they needed to verify this was the final 7/8″ stem you ever purchase.
7/8″ Boxcar Origin Story
From their web site:
“This stem was designed from the bottom as much as be stiff, sturdy, and light-weight. We went by a number of design iterations and consider we’ve reached the perfect mixture of those three rules. In depth, real-world, and machine testing have confirmed this to be one sturdy stem”.
“With respect to torsion, the rounded field form is a few 25% stiffer than the competitors. As for power, we ran it by 1,000,000 cycles of above-normal use stress and not using a single drawback.”
“How’d we get it so gentle, whereas nonetheless being so sturdy? We began with obsessive pc design time, then took the very best high quality, American 2024 aerospace alloy and precision machined it to a .002” tolerance (that’s actually tight for a stem). We use over 20 completely different finish mills, drills, saws, and faucets to make 1 stem”.
