I purchased a few sets of Speedsafe carbon wheels and two pair of rims in October 2018. I’ll be updating this blog post with as-received conditions, observations, as well as some ride feedback once springtime ’19 hits the Midwest.
The 27.5’er non-boost wheelset shown to the left has, no tape, no stem. Both wheels shown, stacked, weighs 1296 grams. The rear wheel weight alone was 721 grams (not shown), so the front wheel wheel weight is 575 grams. Overall a very light weight wheelset.
Borealis Carbondale V2.0 wheelset. These are the second pair of wheels I’ve owned, and I love them. They’re tough, easy as hell to configure tubeless, and a decent weight. The rear rim with the SRAM XX1 XG-1199 10-42 11-Speed Cassette and inferior quality tubeless presta stem tipped the scale at 1694 grams. Assuming the XG-1199 cassette weighs in at the published 268 grams, leaves the wheel set with rotor at 1,426 grams (3.14 lbs). A very respectable weight for an 85mm rim. The front wheel wighed 1329 g, and the Schwable Jumbo Jim Evo Addix Fatbike Folding 26×4.80″ SnakeSkin TL-Easy SpeedGrip stripes blue pulled 1321g on the gravimeter vs the published 1290g

Handlebar Junction A:
Junction Box A, mounted under the stem, to Junction Box B, inside the frame. Or Internal E-Tube Di2 Internal Junction-A – EW-RS910
Lower Junction B:
Junction Box B, The lower, or “B” junction, comes in two forms — an external (SM-JC40) and an internal version (SM-JC41). The external version is fastened underneath the bottom bracket. The internal version is generally tucked inside either the seat tube or down tube through the bottom bracket shell.
