I alluded to receiving some new rims that aren't available anywhere else. That's not an entirely true statement. They are available. It's just that you have to order them direct from the manufacturer in China and pay $35 shipping per rim. That puts that rim at $105 each. Not bad as there are rims that cost more and rims that cost less.
What rim is this? It's the H Plus Son TB14 rim in 36 hole. Currently, this rim is only available from US distributors in 32 hole. After receiving a couple requests from folks for this rim in 36 hole, I ordered a couple boxes of 36 hole rims in polished silver, black, and hard anodized finishes direct from China. Seems there's quite a few folks looking to rebuild their old 36 hole wheels with a silver box section rim to keep the classic look of their bike intact. Box section rims in the old Mavic MA2/MA40 style are about as rare as hen's teeth. The TB14 rim is a rim that is a natural extension of the old Mavic classic rims. The profile matches the Mavic rims to a "T," while bringing it into the 21st century with a 23mm wide cross-section that is great when running 25 and 28 tires. It even gives a 23mm wide tire a more voluminous shape. The rim joint is welded and the brake track is machined. I've built a few of the 32h TB14 rims and they do build into nice wheels. Weight? Don't know for sure as my scale is broken, but they weigh what they weigh - not too heavy, not too light. According to the website, they're supposed to weigh 490 grams.
The guys at H Plus Son were great to work with and only a few days after they received payment, I had a FedEx delivery of rims. The good news is that the 36h TB14 rims I have are only a couple dollar upcharge over the 32h rims at $82 for polished silver or all black and $94 for hard anodized. So, there ya go. They say the aluminum box section rim is dead. I say long live the aluminum box section rim!
