Quick question. I have a set of alexrims r450, 20 in. Could I run 1 1/8 and or 1 3/8 tires on them?

Like stated above. My son rides dk sprinter currently 1 3/8, and I’d like to get him lighter less rotational weight, are these rims compatible with both? Also, wheee can I grab the brake line clips that hold line underneath top tube? Broke one.

Current set up. Swapping cranks and looking for a 34 chainring. Track folks say just swap chainring as it’s easier. But is a 14 rear best?

Should I worry about the rear gear? I’ve swapped every part but rear cog so as to why I ask. Learning as I go. If it doesn’t matter, I’ll grab a 34 and send him out the gate. Added second photo regarding 34 chainring at closer to 50. Month away from 7 years old boy.
