Something is odd about the quality control for Zrace and Ltwoo (may be the same entity) recently got a power meter that was to come with Zrace but came instead with Ltwoo cranks . Then turns out the spindle instead of being the advertised 110 mm is only 106mm. The shortness caused an issue where the crank was rubbing on the bottom bracket. Supplier tried to convince me its not a defect but simply a change in specs. Sent me a video of 2 Zrace spindles which were both different sizes. The big negatives from all of this is I purchased the power meter since Aug 30, 2022 and based on the eta of the replacement crank, I won't be using this thing before Dec 03 (Negatives of buying direct from China. Seller refused to offer expedited shipping free and charged me 10 usd for replacing the defective cranks (why can't ali express be like ebay in terms of customer service)
