While I doubt there is much in the way to aerodynamic drag in it, there are much more aerodynamic cranks.

That can be rectified with a longer BB spindle

I had a long conversation with a friend of mine who in her mid-30s is getting into middle-distance racing on foot. She had some ups and downs recently because she was basing her progress on her local race results. She's been getting progressively faster but finished last in some races. This image that I just found kinda sums up the point that I was trying to get across to her:

Interesting to see that it looks like Hoy is running a) Shimano's and b) cleats with float.

He's most likely getting ready for a photo-op. Not racing, even casually. No strap on the pedal, and those shoes are too clean. Boa retention too. Wouldn't trust that for any sprint efforts.

I like the bike, though. LOTS more pics: https://www.flickr.com/photos/shandc...7645837652432/

Cool. It's like a custom Bareknuckle!
Just kidding. Only kind of. |
id like it more if it had a quill stem. nice bike tho

ive been kicking around building a steel bike too... It's just tough to find a frame with the right geometry |

Performance aside, steel has a beautiful aesthetic. From a visual perspective (there are exceptions), I don't find aluminum tubesets and big aluminum TIG beads to be all that attractive (Tsunami would be in that camp for me!). The nice thin tubes, you can TIG weld, fillet braze, or slip braze it with lugs, or some combination former.
That Shand looks really nice. Fillet brazed joins are a thing of beauty! |

any reason not to call Tsunami? They'll do it DARN cheap, stiff alum, and you pick the geo -

What are you looking for i geo?
- 74/74 degrees - 61cm top tube - around 455mm reach - 14-15cm head tube - Essentially: Short and long Sadly, this bike doesn't exist off-the-rack in steel, aluminum or carbon :( Notice how the Hoy custom steel bike above is short and long based on the bespoke geo set by Hoy. |
I agree with the short and long. My current LOOK KG 233p
- 74.5 parallel - 54cm ST, 56cm TT - 14.5cm HT - 25mm rake/35mm rake. Stock is 25mm, steel fork. Swapped for a 35mm carbon track fork to tighten up the trail. - 50mm BB drop I find this VERY close to ideal (for me ;) ). Be interesting to ride a Marvel and see how it compares to this and my old BT |

Yes. I've never seen anything that high before. A full cm higher than my old BT, and that was high. I know this was done to manipulate the rider's position on the bike (between the wheels). I'd like to experience it for myself to see if it is something that is noticable/beneficial, or if it's just different.

I actually talked with Mr. Tiemeyer about a 35mm BB drop for the bike he made for me in 2011 (my white one). His standard drop is 45mm. He advised against me going with 35mm. I can't recall exactly why. If the merits were there, I would have 35mm drop on my bike. But the merits were not there from his point of view. |

True enough. Hard to argue with someone who's taken an art, made it into a science, then turned that science into an art all of itself. For someone who crafts bikes for individuals, it may have been something that went against what he was trying to do for you as far as geo. I think it might be viable for those that need steeper ST angles (like me, shorter femur/tidia ratio) with a long TT (loooooooooong torso). This would tuck the BB up and back compared to a normal bike, keeping the wheels where they are, thus allowing you to preserve a shorter wheelbase.
Bike geometry fascinates me. |
Tsunami looks cool!
i wonder if they could fix my busted Tiemeyer? Or just make me a clone? |
