This Kirk Pacenti rim was designed with critical input and feedback from Fair Wheel Bikes; to say that we’re excited about the SL23 may be a bit of an understatement. This rim brings together several of our favorite rim design elements, including wide profile, aerodynamic shape, and tubeless-friendly compatibility, along with stout construction and a balanced compromise between strength and weight.
“SL23” may strike some as a misnomer, since this rim actually measures in at a solid 24 mm. Despite its slightly wider cross section, the SL23 is meant to compete with the increasingly popular 23 mm wide road rims. For reference, a road rim historically has measured in widths between 19 and 21 mm. The benefit of a wider rim is that the tire bead hooks are spread further apart, simultaneously rounding out the tire’s profile and increasing the tire’s internal air volume. This allows the use of lower tire pressures, increasing rider comfort while decreasing rolling resistance. Also, when using a standard 23mm-wide tire, a small improvement in aerodynamics will be experienced through a smoother airflow transition between the rim sidewall and tire.
The SL23 features an incredibly strong internally sleeved and welded seam. Following welding, the rim’s braking surfaces are machined smooth and parallel for the best possible braking response. Wear indicators on both sides serve as an indispensable safety feature, signaling when the rim sidewall has become too thin to sustain the forces exerted by the tire’s air pressure.
We recommend that Pacenti SL23 equipped wheels be assembled by an experienced wheel builder. We are happy to provide this service, and can provide helpful suggestions in hub and spoke selections. Please contact us directly or submit a custom wheel build request here.
*Ordering and New Decals
The Pacenti SL23 is going through a rolling decal change. The new decals are already shipping on 28 hole rims. If you'd like us to send you replacement decals for 20, 24 or 32 hole when they arrive please leave a note during the checkout process in the order comments field.
