>>2070563when you're standing straight, straddling the bike, feet flat on the ground, the frame shouldn't crowd your balls. as long as there's a couple, three fingers worth of gap you're good. from your pic, it looks like that frame is too big, dude. your saddle height makes it look ok, but not with you standing next to it. if your knees lock out or if you have to rock side-to-side a little to get leg extension (sometimes you don't notice) then that's too high. but if it's right that's confusing because the height looks ok-ish for a fitting frame with that classic geometry.
those handlebars look really reach-y. if they put you too far forward, modern bars are more compact. you could also get a stem with less reach. I got a cheap Uno brand bar off ali. also the bar is tilted weird but maybe that's to fix the reach.
>chainit looks really clean and the gear teeth don't look worn, so that's good. it's not a bad idea to fully service an unknown chain by shaking it in a jar of degreaser over and over until it's clear, but you could probably just oil it. does it feel/sound crunchy when you have it in your hands?
simple green is good but water based , so after, you have to dry the chain out until the water evaporates internally. hours in hot sun, 20 min in toaster oven, etc, before you oil it and trap the excess SG in there. or you can douse it in WD40 which will Displace the Water, but the thin oil in it isn't thick enough for chain lube. after you put chain lube on, let it soak into the center and then aggressively wipe off the outside so it doesn't attract dirt. you only need lube on the internal parts that rub together.
good luck. there are fixes for frames that are small but too big makes it handle sluggish and emergency dismounts kill your nuts and without flat feet you can't bring it under control, especially when your nuts are on fire. maybe if you're on the bubble you can make it work but generally too big= sell and get a size down
