Another Fit Critique on Speed Concept..
Quote | Reply
Hello, I already had post about my bike fit few months ago, this is new one since i made some changes.

I'm 6.0, 158lbs. Currently I have speed Speed Concept size L. Looks like the frame is a bit small to me as some fitters mentioned in my previous post, despite I had bikefit in local TREK store. Therefore, I made some changes: crankset 175mm=>165mm, got Trek Monobar + 51SpeedShop extensions. In order to have more open hip angle, I moved the saddle forward (still have few cm to max it forward). I'm at my max reach at this moment. I raised up monobar (perhaps too much). Currently I have 3 saddles Bontrager HiloPro, Dash stock, ISM PN3.1(So far I like ism a bit more, but in a future i'm planning to give to each saddle more time). Here is some pictures of my bike setup and video. I appreciate any suggestions.

Do you know your Pad x/y dimensions? I'm on the same bike (basically) and the same size / weight as you - still using the stock monobar. By the way it looks like you have flipped the pivot cradle so that the set screw is in front - apparently that is not advisable even if it buys you 1.5 cm additional reach.

Looks pretty good. Looks like I have the same coordinates as you (615/550). I'm 5'11" / 158. I think a size L is fine, you wouldn't be able to get low enough on an XL.
I use 155 cranks and aluminum Zipp Evo 110s. You should try the 51SS cups, they're 100x better than the stock ones.

What's your CdA?

this is good. you might actually want to slide the saddle backward as your fit progresses and you recruit muscle fibers into your new pedal stroke.

Well you can assemble the front end with it positioned either way with no obvious difficulty. Frankly I haven't heard a technical explanation as to why the set screw should be in the back. Mitch, the "newTrek guy" over on the Speed Concept thread did make a point of saying it needs to be in the back. But he's the social media rep for Trek so what does he know (pink).

I did note at my LBS that 2 out of the 3 Speed Concepts they have on the showroom floor have been assembled with the screw in front. I have mine in the back but I think I'm OK on reach.

looks good!
i have been trying to find a mono plug in adapter and those exact speedshop bars, so its good to see what it looks like together. The bar plug in for the trek is stupidly expensive.

curious - it looks like you have good reach, but hypothetically, if you wanted more, what options do you have which includes keeping the speedshop bars? I have the normal mono s bend bars with slightly less tilt than yours, but am just over 2/3rds maxed out on reach. The plug ins are shorter i believe?

About 550 is the most reach you can squeeze from a size L with the mono plug-in extension by doing all these tricks (cradle mounted backwards, flipping the pad wing etc.). You could do 580 with the stock extension but it's made for midgets so your hands will fall off the ends. It works for some people who like to have forearms on pads but if you're an "elbows on pads" type you're out of luck.

What's your CdA?

Will I get any benefits if I get smaller crankset 165mm=>155mm in my current position?
