I do have a Needle-Blaster HS on my Norther-Lyon. The way Garth described it is the way I assembled it. Seems to work fine.
The Steel Race goes between the top of the needle bearings and below the Bottom Cup. The Bottom Cup does not have a race for the needle bearings. Is the lack of a race for needle bearings in the Bottom Cup a design for needle bearing HS or is it particular to the Tange/IRD design. PS the needle bearings work fine in the Norther-Lyon and I have not experienced any shimmy with it: 35mm trail, 52cm frame, 584-38 wheels, thin walled tubing (7-4-7 TT, 8-5-8 DT) John Hawrylak Woodstown Nj On Monday, May 30, 2022 at 5:04:54 AM UTC-4 Garth wrote: > I was gonna buy one too Drew and wondered just that.
