Quick Answer: If the sticker over the joint of your rim has cracked or broken, but there is no obvious gap at the joint, your rim should be fine to continue using. If a clear gap at the joint is obvious, your rim should be inspected by an experience mechanic. If you are not sure, it’s recommended to have the rim inspected, or send a clear photo of the issue to support@spank-ind.com, or to your regional authorized Spank distributor.It is important to first note, that Spank rims are not welded at the joints. Spank Industries Oozy and Spike rims have sleeved joints, and Spoon rims have pinned joints. All Spank Industries tubeless ready rims, have sleeved joints. Sleeved joints offer a higher strength to weight ratio than welded ones, and allow for a level of flexibility at the joint, which prevents cracking at the joint area. It is perfectly normal for a sleeved rim to flex at the joint area, and for tiny gaps to open or close. Tiny gaps at the joint do not mean the joint is broken. That is exactly what the rim is designed to do, when it takes a hit or overload force, which would be strong enough to break a welded joint. If your rim has a small gap at the joint, it is suggested to have it inspected by a trained mechanic or send images to a Spank Sales and Service Center, but it should still be ridable, and should still be okay for tubeless use if your set up is correct.  If you are experiencing air loss at the joint in a tubeless set up, please remove the tire, and ensure that your tubeless tape is covering the entire center of the rim, and all the way to the bead hooks on both sides. It’s recommended that you use a thin Polyamide tape, like Spank’s Fratelli Tubeless Tape. Thicker tapes can cause issues with tire fit and tubeless performance, and may negate the benefits of the Bead Bite tubeless hooks on your rim.
