Advice welcome
I’ve gone and bought another bike

I now have 3.5 bikes but none are ideal yet …

- Raleigh 39 Ibs
Old Raleigh Mountain bike (39 Ibs) that I got for free - upgraded the tyres as I got 3 punctures in one ride, drivetrain struggling so I bought a new chain but the Chainring was shot and doesn’t like the new chain…

- MTB Chainring worn out
I’m going to swap some bits around if they’re compatible and make this a winter/rough and reliable hack that is comfortable to ride ….
So onto the advice: I've lost 18 Ibs overnight

- Cannondale CAAD 4 R500 54cm 21 Ibs
Cannondale CAAD 4 R500 54cm I’m 5’ 7.5” on a good day, bought Wednesday from an old guys brother who’s never ridden the bike in the winter and looks in really good condition (guy was 78 years old but gave up riding a couple of years ago due to Alzeimers

)
This is my first drop bar road bike for 40 years and after all the mountain bike styles is a real shock for me and my neck/back! Rides ok but it has clipless pedals fitted - I’m not sure I’m ready for that leap as well as getting used to the combined brake / gear shift levers I’m debating getting some flat pedals for it and see how I go
OR
should I get some shoes/trainers that will accept the pedals fitted …

- Unbranded clipless pedal
Rode today with normal ALDI

trainers as I’m on a schedule for 200 miles this week and all the bikes had problems of one kind or another
Got some records today on this weeks route even though I’m going steady on the rough roads couple of pit stops for adjustments / mirror / numb feet and trying to get a grip of the gears so it has potential to be decent enough with no max efforts …

Final query:
I felt massive on the bike and allowing for the footwear / pedal problem am I too big for a 54cm frame ? I felt a little heavy wristed on the bars so they could do with raising a bit more to suit and also the back of my trainers were catching on the ‘dropouts’ occasionally.

- Sizing ?
Feel free to

Alternatively offer an opinion or some 8.5 / Eur 43 shoes to suit ?
