The whole idea of using Titanium hardware is weight reduction. It will never be a s strong as the 4340 heat treated axles, but it weighs far less. When you start to add up 4 King Pins, 4 axles (flips no nuts), TI pivot pins you start to shed incredible numbers when your ultimate goal is to get the weight as low as possible.
There has always been complaints of Grade 2 Titanium bending. it is not even as close, not in the same ball park as 6al4van. This is a fact look at the tensile Strength numbers, or the Modulus Elasticity numbers for the two, (Areospace Specification Metals, web site) it breaks it down very well. What I know for sure, I have had countless Axle's, Pivot Pins, and Kingpins made from 6al4van shipped around the world now since I started machining for anyone that wants them, and have not had to remake a one. All different weight's of skaters, different types of skating, Speed, Jam, Derby, no complaints (Knock on Wood). Wes ![]() ![]() ![]()

2 Mysteries:
1. I actually ordered the RK Speed SL (the ones which aren't trenched through: http://www.boen.it/scheda.asp?idprod=448&idpadrerif=110), and realized they sell the Ti kingpins separately and the SL doesn't come with them. So I sent Boen a note and said "Can you just swap the steel kingpins for the Ti ones in the SL i ordered, and charge me the difference?" - he said sure. I figured i would get an SL with Ti king pins, but what turned up is the trenched through version, in the size i ordered (size 17/180mm). It must be the RK Speed UL (lighter version), but that size isn't available on their website. 2. The page for the RK Speed UL (and i guess the other speed plates?) does themselves a bit of a disservice: http://www.boen.it/scheda.asp?idprod=446&idpadrerif=110. They list "Frame weight 380 g. (16 size)" yet the frames i got (as you can see) are about 360g, and size 17 (180mm) - a full 12mm longer than the 16 (168mm). So after all that rambling, here are the photos: New Boen/Boiani RK Speed UL size 17 - 180mm/7.08 inch wheel base - 361g ![]() ![]() Last edited by PortlandAussie; March 25th, 2016 at 01:46 AM. |

I just noticed that these are NOT 608 22mm bearings, but rather the much lighter 16mm size micro bearings. Still, these wheels with 688 bearings installed are same weight as the RB Turbos without bearings.
