Also got a pair of these, so interested in any info.

The Mavic 230 SBP rims are a classic piece of mountain biking history, primarily known for their lightweight design and use in cross-country (XC) riding during the mid-1990s. These rims were part of Mavic’s lineup of high-performance bicycle components, a brand renowned for its innovation in cycling technology. Here's a rundown of what makes the Mavic 230 SBP notable:
Design and Construction
- Material: Made from aluminum, the Mavic 230 SBP rims were designed as a double-wall construction, which provided a balance of strength and weight savings. They featured a box-shaped profile with flat sidewalls and internal channels for added rigidity.
- Weight: These rims were exceptionally light for their time, with weights often cited around 360-375 grams per rim (depending on spoke count, typically 32 or 36 holes). This made them a favorite among riders looking to shave grams off their setups.
- Finish: The "SBP" designation stands for "Silver Braking Performance," indicating a silver anodized finish. This distinguished them from the "TIB" variant (a coppery titanium-like finish). The silver finish was intended to offer decent braking performance with V-brakes or cantilever brakes, common in the era.
- Eyelets: They came equipped with single-wall stainless steel eyelets, which helped distribute spoke tension and reduce the risk of nipple pull-through, though the rim’s thin walls still made it somewhat delicate.
Intended Use
The Mavic 230 SBP was marketed as an ultralight XC rim, ideal for riders prioritizing efficiency and speed on less aggressive terrain. It was not built for heavy-duty mountain biking like downhill or freeride, where durability under high impact is critical. Riders often paired these rims with high-quality hubs (e.g., Shimano XT, White Industries, or Hope) and lightweight spokes for a responsive wheelset.
Strengths
- Lightweight: At under 400 grams, the 230 SBP was among the lightest mountain bike rims available in the mid-90s, making it a go-to for competitive XC riders or weight-conscious enthusiasts.
- Responsiveness: The low rotational mass translated to quick acceleration and a lively feel on climbs or technical trails.
- Durability (with care): For lighter riders (e.g., under 150 lbs) or those sticking to smoother trails, these rims could hold up well and stay true with minimal maintenance.
Weaknesses
- Fragility: The trade-off for their light weight was reduced durability. The thin sidewalls were prone to denting or warping, especially under hard landings or impacts (e.g., rocks, jumps, or rough trails). Many riders reported "tacoing" (severe bending) or sidewall failure after crashes or big air.
- Truing Issues: Due to their lightweight construction, they could lose trueness more easily than beefier rims, requiring frequent adjustments.
- Not for Heavy Riders: At weights above 175-190 lbs, or for aggressive riding styles, these rims were often deemed too delicate, with replacements like the Mavic 231 or 261 recommended for better strength.
Historical Context
The Mavic 230 SBP rims hit the market around 1994-1995, replacing or complementing the popular Mavic 231. They were part of a trend toward lighter components as XC racing gained prominence. However, their fragility led to mixed reviews, and Mavic eventually phased them out in favor of more robust designs like the 217 or 261. Today, they’re considered a retro gem, often sought after by collectors or builders of vintage 90s mountain bikes (e.g., GT Zaskars, Fat Chance Yo Eddys).
Modern Perspective
While innovative for their time, the Mavic 230 SBP rims don’t match the durability or versatility of modern XC rims, which benefit from advancements like wider profiles, tubeless compatibility, and stronger alloys or carbon options. They remain a nostalgic choice for restoring period-correct bikes rather than a practical option for contemporary riding.
If you’re looking at these for a project, they’re best suited for a lightweight XC build.
