I have finally acquired enough spare parts to start considering building an N+1 from scratch. I have even looked at steel lugged frames just to have one. I have a Shimano rear derailleur and a SRAM rear derailleur that will cover a 10 speed. I have several wheel sets and with different 10 speed cassettes mounted so I want to build a 10 speed. I also like bifters so I want to build one with bifters so I don’t need down tube shifter bosses.


So here is the question. Steel used to have a lot of flex in the bottom bracket area, at least in my old Viscount Aerospace Pro, that was pretty much gone in my last Aluminum frame. Are the newer steel frames stiffer than the old 531- 4110 frames or if I plan on climbing should I look at something else?
