Bottom Bracket Selection Guide
BBInfinite 1-Piece, Hub-style T47 vs. Sram 47: FIGHT!
The stock SRAM T47i bottom bracket in this Émonda SLR7 is no match for our BBInfinite, 1-Piece, hub-style module. In this head-to-head we give the stock bottom bracket all the advantages we can, even taking off all the pre-load, but nothing can help it overcome the drag caused by bearing misalignment that plagues any 2-piece system. The BBInfinite T47i module shown in this video is our entry level ABEC-7 equipped model, and it was completely installed, pre-loaded, and ready to ride when we did the After-spin test. Many thanks to Kelly and the crew at Trek Bicycle Little Rock for teaming up with us to make this video possible.
