I love riding my cross bike on challenging terrain. A typical ride involves 2000 of climbing on paved or unpacked roads, 2 hours of challenging myself on blue MTB trails and back to the paved or gravel descent. This crankset is super stiff and has a small enough small ring to enable the toughest off road climbs. Top end speed is nearly unchanged. Versatility of the bike increased dramatically.
I installed the SL-K Modular BB386EVO crankset with 3046T rings on my rando bike's BB30 bottom bracket using FSA adaptors. My objective was to replace the standard 3450T alloy crankset to take advantage of the improved range of gear ratios. The front derailleur could accommodate the 16T difference and only required it to be lowered to properly align with these smaller chainrings. This was a very simple swap. I shortened the chain and was back on the road. The new gear ratios have made for more pleasure long distance rides that include any significant climbing. I have subsequently installed this same product on my CXgravel bike by using FSA bearings made to accommodate the BB386EVO spindles in the BSA bottom bracket. This set up has also greatly enhanced my dirt adventures.
