  I don't think you quite get the low trails geometry, it doesn't matter if it's in the wrong end of the axles, it will still be fine to ride, it's only an issue if I have my saddle set far too forward putting my body weight on the handlebar only, instead of saddle/bar.

  I understand what you mean. I just wanted to ask if you had a steering issue with 120mm stem in mind.

  I understand how the low trail geometry works. It's just that putting weight too forward ahead could even affect a low trail geometry. It's not the handlebar bag that would dull the steering, it's the weight of the torso, especially if the cyclist is heavy on top.

  I have a very short chest for my proportion.

  I thought so, I could say we are in the same club. Couldn't tell from the photos...

  The latest photo with black/tan Hetres looks awesome. Saved into my favorite randonneur photo album. The bike proportionally looks right.

  I had to edit this...

  Oh, I thought you used 120mm, must have missed the part where you picked 100mm.

  The handling issue I pointed out was because I thought you had a 120mm stem. Even with a low trail geometry, you don't want to move the handlebar too far ahead. Both your body weight and the bag's weight shift to the wrong end of the axle. 100mm seems like a much better choice.

  Are you 184 cm tall as stated in the notes of the builder at the first page? I guess I'm shorter than you (176cm), with a slightly longer inseam (87.7cm). My frame is a 60 x 56 with a 85mm stem. Your arms don't look short in the photos, is that the issue? Couldn't figure it out the reason for 53mm top tube...

  Well nevermind, as long as you love it, numbers don't really matter. I bet it rides as good as it looks!

  I just happened to see this whole story of the build, that's a very nice bike you got there! I'm a die hard fan of box tubing!

  From page one I've been trying to understand why your frame builder picked a super short top tube and mated it with a super long stem. You could get the exact reach wi a longer TT and shorter stem.

  Are you experiencing any toe overlap and/or handling problems when the bag is loaded?

  That stem on that yellow bike. You might not like it but I think it's a treasure! Early Cinelli Milano stem. That dropbar is Soma Major Taylor (25.4 clamp size) and I see no spacers. It's probably rarer than anything... They're produced with 26.4mm clamp size and some rare productions had 26.0mm. Never seen one with 25.4mm

  Rims look like old logo Mavics, probably Montherlies or Argents. They're arguably the lightest tubular rims of the era. It's a guess from that red sticker and rim design. The headset is Stronglight with cylinder bearings, it's light as a feather. I'm pretty sure that San Marco saddle has titanium rails too. It's an old school weightweenie case, but why use steel stem and bars when you have so many superlight parts? For the looks? Change those dull aluminium parts then!

  I don't think that bike is used in track, front brakes aren't allowed in velodromes, right?

• Seatpost Stem 26.2 to 27.0 mm

  I'm building a pre-war track bike replica, gathering parts mostly from eBay. I got my hands on a beautiful NOS Campagnolo Record Aero seatpost, to fit a Dawes frame I was planning to use (26.2mm). After that purchase, I got myself a custom frame that has Cinelli bottom bracket and Campy dropouts, can't decide if it's a real Cinelli Pista or a custom build frame just with the parts, it came repainted w/o any decals. I can't afford not using the Campy seatpost and need a stem that's going to convert 26.2 to 27.0 mm. Turned Google upside down, can't source anything this size. I'd really appreciate any help on this, even a contact that could make me a custom stem would do...
