Questions about Gazelle Formula Race (Reynolds 525)
Hello,
I have questions regrading the road bike frame gazelle formula race using 525 Reynolds tubing. I purchased a frame but I need to assemble it for a build. I need guidance from people with experience with this frame.
1) Headset: is what stack height/headset model are you using on your bikes with this frame ?
Originally I took a Tange Seiko ISO headset since I saw an online listing(*) stating a 26.4 crown race. I managed to fit the cups and cones on the headset but I could not fit the 26.4 mm cone into the fork crown and therefore I ended up bringing the fork to my LBS and they reduced the crown race down to 26.4 mm. Then, I realised that stack height of the headset is too short for the frame when trying to assemble everything, about 10 mm of visible threading...
Now, I measured the required headset stack height by subtracting the frame head tube length from the fork shaft length and I obtained around 40 mm.
2) Seatpost: What is the diameter of the seat post do you have installed on your bike frame ?
I tried 27.2 mm since it was listed in an listing (*) selling the same frame model. With the saddle mounted I managed to fit the 27.2 mm seat tube, but with a lot of force an squeezing. Is this normal?
3) Bottom Bracket: What length for a good chain line ?
I have "Shimano 600 tricolor" crankset and Dura Ace 7403 hub 8 speed HG rear wheels that I will mount on the frame. I looked online and opinions are divided between 113 and 116 mm a for bottom bracket length (in Shimano 600 tricolor velobase page)
(*) Sorry guys I cannot yet post links it is a website called velosaloon(dot)com
