I think it looks pretty good. I think (but don't no for sure) you can get some of that reach back. Also are you on the low far stem?
How does your power feel being so high over the BB?

you have a reasonable position. In order to maximize it, you'd need to learn proper posture with regard to shrugging, rounding, and turtling your head.

On the other hand, or rather in addition, you could go lower and remove that spacer. I'd do that to start and add some tilt to your extensions. Definitely max out the reach available.

I think the crank length looks fine from a positional point of view, but really it's more a personal preference with feel, comfort, and power.

I don't think he's on the low far. So there should be more vreach available.

@fishbum I'm probably on the steep side at 80*. I'm not sure how I'd feel moving going back... I've had glute and back issues in the past, not sure how moving back would affect them. I feel like it could add a bit more strain to lower back and glutes... maybe.

@ericMPro I used to ride with a lot more tilt. The thing about tilt on the speed concept is that depending on how far the pad wing is placed on the mono extension and where your elbows are on the pads, adding tilt often increases pad stack as well. I guess a good compromise would be to go with the 15mm spacer and angle up more. I'd probably still end up with the same stack but hopefully higher hands would be more aero.
Another option is to use extensions with higher rise > 110.

What's your CdA?

Yep, that's the low far.

What's your CdA?

Ok...Hmm
Low far on the large Max's out at 584 reach.
I no you loose some with the extension plug but 4cm?
Sorry for the questions! I have been really trying to educate myself about the SC.

Yes, the plug-in has only 3 holes for the pad wing vs 4 on the stock mono extension. Holes are spaced about 3 cm apart. I guess it also depends on what pads you use. I have the new 51 SpeedShop pads and they're mounted as far as they would go.

What's your CdA?

Oops.. just re-measured and effective seat angle is 86*. That's if I measure through BB and hip joint... not sure this is how it's supposed to be measured.
How steep is too steep? :)

What's your CdA?

Hey all,

I had a buddy ask me to post on here as I am literally in transition of the standard mono bar to the mono plug in.

I see some questions floating around - first of all the difference between the standard mono and plug in bridge mont is 1 inch. Thus making the armpad bridge 1 inch or roughly 2.5cm backwards or shorter.

The Gen 2 SC is rather amazing - first of all unless you have absolutely tiny forearms and hands you are not able to use the full reach of the bike - it’s just not possible with the standard mono bar.

The front end has a ton of tricks and changes you can do to keep moving forward also. I am certain the OP could still keep making the arm pads continue to move forward if his arm length is not the restriction at this point.

The tricks are;

-Turning the armpad bridge around and arm pads as far forward as allowable
-disassembling the mono wedge/roller and turning it around so the grub screw is in front as opposed to the rear

If I have a opportunity tomorrow I am more than willing to post a bunch of photos of what I am referring to. I would be willing to bet in real world application you can actually get more armpad reach with the mono plug in than you can the standard mono due to the restriction of the bar length itself (even despite the plug in being reduced by 1 inch).

Cool,
I did turn the pad wing around already. I wasn't aware of the cradle / wedge piece trick so that may be an option too but I think you missed the part where the plugin has less holes for the pad wing (3 vs 4) so given the distance between holes which is (2.5 or 3cm can't remember right now) and the 1cm you mention you get about 3.5 - 4cm shorter reach than the standard mono extension. Arm length is a restriction at least for me. I think the mono extension in designed for someone who has forearms on pads not elbows like I ride.
For someone who likes an elbows on pads, shiftter in hand position you really need to have tiny forearms to go over the tips.

For me, maybe I'm riding too steep and going back on the seat and lower might actually be beneficial both in terms of aero and more reach.

Hey trailerhouse - I typed 1cm originally when it was suppose to be 1 inch. I corrected on the post and am not sure why my phone autocorrected it. I apologize on that.

I would recommend that you try removing the mono and flipping the pivot assembly around to give you a little more forward reach.

I don't think the camera angle is a good one for measuring how steep you're riding. Ideally, I like to center the lens with the BB where you look to have it centered on your water bottle cage. The height you have the camera at looks okay.

I'm curious what saddle you're running and what the setback is?

If you are running ~86º that is pretty steep and with your height you'll likely run into reach issue like Fishbum has.

In fairness even with the seat back I'm still at 580 LOL.

580 is the new normal!

My YouTubes

I guess ur right

That's a Cobb Max and it's set at 0 setback but.. If you look at the cobb max shape I really don't count that last section of the tip where your junk is supposed to go over. So the first usable part of the saddle is about 3-4cm behind the BB.

I did use a bunch of saddles in the past and I've been on an Ism pn3 most recently but I've decided to go back to Cobb as this was this only one that didn't consistently cause numbness together with the Hilo RXL. My PN3 was set a lot further back but that's because you're supposed to ride those saddle on the tip.

I don't wanna rant about split nose saddles but at lot of the designs are well intentioned but poorly executed. They have a huge relief channel which is supposed to resolve numbness but yet the channel narrows down to nothing at the tip exactly where you're supposed to sit so basically it's useless.

Trailerhouse,

I updated the SC thread with a bunch of measurements and photos from my bike yesterday (its a medium however). I figured it would be most useful there and hopefully of some use to you;

https://forum.slowtwitch.com/...st=last-2844072#last

It is post number 9282

Update: made a few changes since last week:

- saddle moved back about 1cm and reduced saddle tilt
- removed 25mm spacer, replaced with 15mm spacer
- reversed mono extension cradle and got back an extra 1cm of reach - reach is now 550
- added back mono extension tilt - this reduced stack a little bit since pads are pretty far fwd on the mono - stack is pretty much unchanged at 615

Comfort increased significantly - must have been adding back tilt extension and possibly reach. Felt like saddle pressure reduced and there is definitely less strain on the upper body. Power felt great but then again I only did 1 workout with a 2x10 at 80%.

Things to try next:
- reduce extension tilt to find the lowest setting where I'm still comfortable
- I'm planning to do some field testing in the following weeks and establish a CdA baseline. Found a good loop and might even get some time on an outdoor 333m velodrome.

Also included some shots with my Giro A2 helmet... For some reason I always felt pretty fast wearing that helmet. I had fogging issues with the Aerohead but I think I'm going to get one again to test all three and find out which is really the fastest for me.

I really should take precise notes on these things :) Moving saddle back was one of the first changes I made earlier in the week.
I thought I was a bit to steep and wanted to move seat back and see if that changes how I perceive effort in some way. Looking at the before and after it looks like effective seat angle hasn't changed too much at I'm at about 85* in both positions. I guess I just gravitate towards sitting closer to the BB for some reason.

The one thing that's missing from the list is dropping the saddle down about half cm as well. I did that to compensate for moving saddle back. Tilting the nose up was done because I felt like it distributed too much weight towards the front when it was tilted down.

I definitely feel more balanced with the added reach and the extension tilt. Upper body is a lot more relaxed.

Thanks!
I'll try to move it a couple of cms more forward and see how that feels.

Okay, so I had my first attempt at field testing today. There's a crit course close to where I live and part of it's a 525m loop. It's pancake flat but it's closed to cars and I was able to get a 5 loop run with no interruptions and no one around. Weather was good: 69F, 0 wind, 100% humidity. I did a few shorter runs and numbers were similar.

I used the CdaCrr Android app but also recorded on my Garmin and ran it through Aerolab and numbers seem to match.

So my CdA is...... drumroll..... 0.274 *sad trombone* I was expecting to be closer to 0.25x.

Good news is that my training sessions this week went pretty good - had plenty of power and felt a lot more comfortable than before. I'm thinking I can definitely hold power for longer intervals which I sort of struggled before once I went over 88-90%.

Tested with the setup above. Any ideas what to try next?

I'm planning to test next weekend again with the same set up and see if I get repeatable numbers before I start to try different things.

What's your CdA?

What helmet?
Are your hands up as high as they can go?
Is the arm pad tilt maxed out?

I tested with the POC. I think extension tilt is maxed out
