Geometry Continued and Tubing

Below is rSogn geometry with standover heights for different tire sizes. Do email me here questions about frame sizing.

Tubing

Here is what I would start with for all frame sizes:

• rSogn: Standard diameter 8/5/8 top tube and 9/6/9 down tube.

Notes:

• The XL rSogn probably will have standard diameter 9/6/9 for both tubes. 
• Heat treatment may be considered; This will increase stiffness strength and price.
• 7/4/7 may be prone to denting.

Color and Revisions

First thing first, here is what I think works better for the rSogn:

Now, based on numerous email conversations with those who had pre-ordered the rSogn, I thought it would be prudent to revise the geometries of these models.

The table below is based on a smaller tire size at 38c for the rSogn. The resulting standover height of each frame size is now lower. There are some other revisions in response to the conversations as well.

Moreover, each illustration shows an approximate minimum saddle height and a 10mm spacer that doubles as a cable hanger. Please also note revisions in the lengths of top tube, seat tube, and  head tube for some and/or all frame sizes.

Colors

As promised, here is what I have for the rSogn. I am wrestling with these two shades of metallic pewter:

The first one, 7668, is dark silver. The second one, 7670, is the same with a hint of bronze. Which one should I pick?

On Schedule

Greetings and Salutations,

Here we are with a design recap of the rSogn posted below. The past couple weeks were incredible to say the least. Although we are taking the Pageview feature with a grain of salt, we are stoked that this blog has received thousands and thousands of views. We thank all those who contributed to the process toward the creation of the rSogn.

Now we look forward to receiving (and riding) a prototype before finalizing details prior to production in a couple of months.

Also be sure to join our mailing list for updates and whatnots:

rSogn Top Three Colors

In no particular order:

1. Rawland Red: http://www.wired.com/autopia/2009/12/rawlands-la-auto-show/

2. Pewter

3. Blue (specify shade)

All metallic a la the Drakkar.

rSogn Color

Here is the plan:

Wednesday - Nominate your color(s) of choice for the rSogn, and explain why. 

Thursday - Announcement of top three colors. Pick and/or prioritize your color(s).  

Friday- Announcement of the color for the prototype rSogn. 

You may begin...now!

Where I am on...

The rSogn:

• Rear-facing seat post clamp slot
• Lowrider and water bottle mounts for the low-trail fork
• Three water bottle mounts on the frame
• Seatstay rack mounts
• Equidistance rear fender mounts facing the tire
• Brake cable stops at 10 o’clock
• Stainless steel chain hanger
• Down tube shifter mounts
• 132.5 rear spacing. Or should it be 130? 135?
• TIG-welded (not filet-brazed) pump peg on the seat tube similar to this:

Comments?

Anything else?

Tuesday Tidbits

Now that we are past halfway through the process of designing rSogn, I wanted to share with you the following comments I have received on this process:

Your collaborative approach is refreshing in this industry.

Thank you for the opportunity to be part of this collaborative effort. I don't have the kind of technical knowledge and experience some of the other contributors have, but it's still exciting to feel like you are part of a team working to create a great riding bicycle that has wide-ranging capabilities. Kudos to you for this project. Some might say too many cooks blah blah, but I think that has not been the case here. It's been a lot of fun.

Looks fantastic. I'm following the discussion and would comment, but I can't think of anything I would add to the discussion that others haven't already touched on. As the design is revealed, I am liking all of your decisions.

I see Rawland as the direct descendant of the Bridgestone XO. While other companies are fixated on capturing the look of the nearly two decade-old bike, yours seems to capture the spirit of the XO-1...Much appreciated. I'm a retrogrouch, but I'm a practical one. I'm eagerly looking forward to seeing this frame develop.

I am excited by the new rSOGN design and would probably like to get on the pre-order list. I would like to wait till the the design is "finalized" before making the decision - but each day the design just keeps getting better. Thanks...

I just wanted to send you an email and offer my gratitude for you opening up your design process to potential customers...I have designed a few bikes myself and I spent countless hours pouring over each detail and revisiting practicality, function, aesthetics and more...Anyhow, I just wanted to reach out and give you my best.

Anna and I hope that you all too have the same experience. We also wish for for the process to avoid the groupthink phenomenon. We have been successful in that regard thus far.

Additionally, I have been asked if we may take pre-orders now. After discussing with Anna, I decided to keep the schedule as is. That means we will start taking pre-orders on Friday, October 1, after making announcements of final design details and colors (!). However, you may certainly email me to get on the list.

Last but not least, I have also been asked about offering the rSogn in titanium. Email me if you are interested in this option.

rSogn Updates

Here is an updated geometry with the addition of size Small. This size is mostly proportional except for head and seat tube angles at 73 and 72 degrees, respectively. That is the best I can do without further compromising the proportion and ride.

The geometry also shows a slight change in rake from 60mm to 63mm. I decided to tweak the rake after riding a 60mm rake extensively with the Neo Moto, the Quasi Moto, the Hetre, and the Pari Moto over the weekend. This was also to address a minor design dilemma I had with the smaller frame sizes.

The standover height is now based on the Neo Moto 58c.

As far as tubing, I am now leaning toward 8/5/8 for all sizes. There might be a slight variation among certain frame sizes. I will share further details as they become available.
