Long-Term Comfort and Comparison

I've been a long-time user of Selle Italia saddles, and the standard SLR Carbonio has served me well for years. This review focuses on the SLR Boost 3D Carbonio, a supposedly more comfortable iteration. My previous experience included a brief encounter with the Specialized Power saddle, but it didn't suit my needs. Therefore, this review centers on a direct comparison with the standard SLR and personal experience with various saddles over several years.

After a 150km ride, I found the SLR Boost 3D to offer marginal improvement in comfort compared to its predecessor. I'd estimate a 20% increase, not the expected 30%. While initially feeling very cushy, it took some time to fully break in and achieve optimal comfort.

Key Comfort Zones and Saddle Fit

The 3D material significantly enhances the softness of the saddle's outer edges. However, my main pressure point remains centered, making the central area's comfort crucial. I prefer a more square seating position, therefore a large scoop is unnecessary for me. The saddle's shape and my seating position work well together.

My saddle setup includes a relatively horizontal position and a large saddle area to accommodate my sitting style. This setup minimizes pressure points and is instrumental to my comfort.

Addressing Saddle Sores and Hygiene

I used to struggle with saddle sores. Now, I prioritize hygiene and use preventative measures like Aussie Butt Cream with lanolin and regular cleaning. This proactive approach has significantly reduced the risk of saddle sores.

Price, Recommendation, and Comparison with other Models

The Selle Italia SLR Boost 3D Carbonio is quite expensive, costing around 700 Australian dollars. Compared to the standard SLR Carbonio (available for around 240 AUD on sale), the price difference is significant. The standard SLR Carbonio offers already excellent performance. Therefore, the price premium for the Boost 3D needs careful consideration.

I also own the manganese version of the SLR and have noticed comfort differences between the two. The carbonio version seems softer due to its materials and rail type. The manganese or titanium rail versions might be less comfortable.

Conclusion: Is it Worth it?

Ultimately, the Selle Italia SLR Boost 3D Carbonio offers marginal comfort improvements over its standard counterpart, but at a steep price. The increased comfort is noticeable but not transformative for me. While the 3D material enhances softness, the overall comfort improvement isn't substantial enough to justify the significant price difference for everyone.

Consider your budget and riding style. If you have the budget and haven't found a perfect saddle, it is worth a try. If you already have the standard SLR Carbonio and are happy, the upgrade may not be necessary.
