Hi I made this commuter from a kind of challenge I gave to me, it was to create a commuter from the cheapest "new" MTB I could found on FB marketplace on my city (north of Mexico), and using some from my spare parts bag, also part of the challenge was to make all the bike (except the rims) of steel (to avoid galvanic corrosion),
it has some characteristics:

1) MTB rigid rear and fork, Lower size frame: (is about 2" smaller) to mount and dismount easily, also the top tube will be closer to use Drop Bars
2) Drop bars & aluminum brake calipers and steel levers (from spare bag): multiple hands position, i like to brake on the hoods and on the drops while descending, old style levers = less friction on cheap calipers
3) High Bottom Bracket: the bottom bracket is 5 cms higher than my road bike, it helps on horrible roads and bumps also climbing some irregular steps
4) 26 x 2.15 Tires without knobs (new): less rolling resistance but with some bumps absorption
5) 7x3 transmission (spares bag): i live on hilly area, with a 48/38/28 crankset and a 14-28T freewheel enough to downhill with decent speed and to climb without exploding my 40yo+ meniscus
5) Cheap Lights, Bell, fenders and rear rack with his bungee cord (all from my spares bag)

I censored the frame brand because it doesn't deserve to be promoted.Im thinking to change the frame for a chromoly 80s -90s rigid, but if I did it I couldn't let it outside locked without worries.
Any advice or recommendations to improve this commuter bike are appreciated.
