Road Bike Frames, Wheels & Components / Re: VeloBuild VB-R-268 frame

I run a small Etsy shop on the side

You don't happen to have a link to your Etsy, do you?  I don't know know if you remember, but talked about an adapter you were making for hiding the Zeno couplers under an SMR stem.  (https://chinertown.com/index.php/topic,4455.msg50564.html#msg50564)  Figured I'd see if you sell it instead of having to reinvent the wheel.

Road Bike Frames, Wheels & Components / Frame with internal storage??
« on: November 02, 2023, 11:00:23 AM »
Are there any frames from Chinese manufacturers that have internals storage?  Something like the Specialized Diverge or Trek Domane.

I've looked at the major vendors, but can't find anything.

We have a first design, and overall it seems to address most of my request.

The only missing piece, and I wanted to ask you, is this

From the drawing, I believe that is the chainstays looking up. In my understanding, the only way they could design that to fit the 42T chainring and the 50C at the same time is by putting a flattened part in the right chainstay. That means that the cable needs to go out around that part, correct? Do you have any ideas or suggestions of how can I avoid this (if at all possible)?

I'm also going through the process of having a Ti frame built by Waltly and asked for internal routing with roughly the same tire clearance, etc.  While you do need to route the cable on the outside to get around the chainrings, those 2 oval cut outs on the chainstay are for the cable to go back into and then out of the chainstay.  There may also be a place on the yoke to tie the cable so things stay in place.

I'm just curious, is your frame fully integrated or is it semi-integrated and you just want to clean up the cables before they exit out from the stem?

I'd just opt for an integrated stem+bar that already have built in cable routing. That would probably cost a lot less than some of these boutique stem options. It seems these stems with hidden cabling weigh as much, if not more than a standard stem.

I personally like exposed cables, it looks more industrial!  ;D

The frame is fully integrated, but I want access to the hoses for the hydraulic brakes so I can pack the bike down for travel in a Orucase Ninja bike bag (you need to be able to take the fork off).  I'm planning to uses hydraulic quick disconnects similar to the ones Sakizashi posted and while I can make an FSA SMR stem work, imo, it's not the most elegant solution.

Pros of the Zeno System vs. Formula:
- Assembled they are nearly 10mm shorter 2mm smaller in diameter.
- They can be placed anywhere on the line.
- They do not require special cables.
- You can reinstall them a couple of times in the case you kink a hose or something goes wrong with the install.

Cons:
- The downside is that the male end of the hose is larger and requires a 10mm hole to pass them through.

That "con" is not an issue with the FSA SMR stem and I designed my own headset top caps so I could pull them through to drop the fork.

Oh dang, you might have just swayed me over to using those.  And looking more closely, I really like the volume adjuster they've got!

These are Zeno couplers. Unlike the Formula couplers you can put them anywhere along the lines.

I prefer them, but DM me if you want a set of the Formula ones, I have a set I have been meaning to to stick on ebay for a while.

If all you are looking for is a stem that has a routing hole at the bottom, the Pro Superlight might be another option, but I feel like the couplers under that stem wouldnt be very good looking.

Yea the aesthetics are the sticking point for me here.  I'm looking for something that will give easy access to the couplers, but still look good and be relatively inexpensive.

I am curious about those Zeno couplers.  Is that a particular reason you're going with those instead of the Formulas?  Are they small and/or shorter?

I hadn't come across the Control Tech stems.  From what I can tell (the pictures I'm seeing aren't super thorough), it looks like it might work.  I'll probably need to make an adapter to ACR spacers though.

That's an interesting idea with the SMR stem.  I didn't realize you would route hoses internally out the center of handlebar with that one.  I thought it was only externally through the sides.  What are those connectors you're trying to fit?

My other thought was getting the handlebar that Airwolf uses for their YFR068 frameset and putting the Speedlocks in the channels that run under the tops.

Road Bike Frames, Wheels & Components / Stem with an open bottom?
« on: September 23, 2023, 02:07:49 PM »
I'm trying to find a stem similar to the new Giant SLR Aero stem that has, what is essentially, an open bottom, but for the life of me I can find anything more reasonably priced (they want $300?!).  The channel is used to route internal cables while still making the bike easy to adjust.  My hope is that I can find a stem with a similar channel so I can install some Formula Speedlock hoses to have a travel bike that still has an integrated front end.



Does anyone know of a stem with a similar feature?

I'm looking at sourcing the fork from this frame for a separate build since it uses the flip-chip system. 

Can someone measure the axle to crown length for me?  I can't find it anywhere.

This site looks like a good source for headset-specific bearings:

https://www.airevelobearings.com/product-category/headset-bearing-kits/

You could even try the Aspero 5 specific kit since that's what the YFR 068 is a clone of.

For those in the US, how long was the shipping for this frame?  Their website says 7-10 days, but that seems really fast.

Wow, this frame checks off everything I'm looking for.  Also interested if there's a direct vendor selling this.

also I could get some machined out of al too. maybe.

I feel like at that point you might as well just buy another set from Velobuild.  The spacers I got from them were ~$30 usd shipped.

I hear ya.  If you're set on using a consumer FDM printer, you can design in some holes for metal pins.  Then you'd have some more solid material to take up the preload vs the plastic.

Best of luck!

Before Velobuild started shipping the split spacers, I designed and printed spacers for my 177.  They were 1-piece but with a split and sort clipped around the cables and steerer.  A 2-piece design would have been better.  You will definitely need to use something like nylon at a minimum for this and print at 100% infill for as solid of a part as possible.  In the end I just got a set of their split spacers and used them. 

Why do you need custom spacers?

Thanks! Just to be clear: Did the Velobuild stem include a topcap with a hole that allows the steerer not to be cut to size? Like the SL7 stem, where a different topcap with a 1 1/8 inch hole allows to run spacers above the stem.

It does not (at least mine didn't), but I ended up designing and printing a cap:
