Unfortunately the 16" to 26" jockey wheel spacers don't fit my current 20" bike. Your tubes on the bike are a fewmm thicker for them.Technically, the training wheels I bought are a set of Wald 742 training wheels for 16-26 bikes can measure the diameter of your tube with a tape measure to see if it will fit, however the Wald 10252 jockey wheel kit for 16-20 wheels I believe includes spacers that will fit up to 1.25" tubes but at Will also work with 742 jockey kit wheels if needed If you call Wald LLC at 1-606-564-4078, speak to the secretary and get an email from one of their sales reps, preferably Dan, they will email you Address to which you 10 U S dollars can send just to buy 10252 jockey wheel struts and they will include a 1" adapter set to keep struts snug to the frame. It's a hassle but well worth it as they seem very thick and strong. My bike also has a shorter axle and they go with everything except the tubular brace. When you get new braces, they will be perfect. Ten dollars more. Expensive but perfect. Another way to find the perfect training wheels is as follows. 1877bikeaid answers questions via callback.
