Top Tips: as with all our kids cranks, we always add helicopter tape to the face of the crank arms to protect from kids feet rubbing (especially without cleats) when the cleat position sets the shoes very close to the cranks. Fitting to the HUP xc 13"-19" (73mm shell, boost) use the 2mm spacer on the DS cup and a 3mm offset chainring. Fitting to the HUP xc20/24 (73mm shell, non-boost) use the 1mm spacer on the DS cup and a 6mm offset chainring. However, frame tolerances may override these - so ensure you use the correct spacers to acheive your correct chainline and crank arm spacing!

If using HUP cranks on a non-HUP frame, use the dimensions below to check for fit on your frames chainstays...width of inside of arms = approx 146mm. More install info here.

Very nice nightstand organizer
Color: Bootlegger Brown, Size: 10.5" x 7" x 1.5"
I was looking for a way to keep all my essentials together at the end of every day, so I had started looking at valet trays. These caught my eye as they're rawhide that are offered in a few different tones. I chose the Large in the Bootlegger Brown tone as it goes with pretty much every decor and suits my style. It's a great shade, and the color is rich. The size is perfect for my needs. Watch and ring at one end, phone on top of slim wallet on the other, and two small sets of keys in the middle. Not crowded, but also no wasted space. The leather is very thick, and the tray keeps quite rigid, despite its size. The edges are turned up just enough to contain your items, but not so much that you feel like you're digging down into something. One minor gripe: I wish the bottom were somehow weighted to keep the tray from "wiggling" when grabbing items out of it. It would make for the perfect tray. I may try to affix something under it that's flat and heavy (but thin), so I'm not too worried about it. Overall I believe this is a fantastic product. I would recommend this for anyone who carries at least a half dozen EDC items as you're sure not to forget anything when preparing to head out for the day.
