upgraded / replaced my chain this weekend. wallke x3 pro uses KCM z-series narrow chains with 128 links. most 8 speed chains are either 114 or 116. so you would definitely need to buy 2 chains for our bikes. One main chain and one donor chain to grab the extra chain links. Replaced the chain with kmc x-series with the Altus derailleur... smooth shifting
