Re: Velobuild VB-R-177 Looking good! My only advice, be careful with that stem. That project is flawed, the carbon topcap is too frail and loose to apply proper compression, without it the stem/fork will also have some play after a long ride.

People are switching to FSA or the Deda Superbox in my case.

Just wish Velobuild would stop selling that stem and offer a proper solution.

Hello everyone,
Herewith my contribution with my new Velobuild VB-R-177. This has been my first bike build ever and it was a fun experience.
I made my choice buying from Velobuild. Couldn't decide between the VB-R-166 and the VB-R-177 but I finally decided to go with the VB-R-177.

My objective was to build a budget road bike. Therefore, I took my time and looked for used / discounted parts from the internet. I was very happy with most purchases (especially the group set). But it didn't always work out great. One of the disks appeared to be not completely round, so that needs replacement. Also buying second hand, means sometimes that some small parts are not included. Especially in my case as an inexperienced DIY bike mechanic, that appeared to be a challenge since most of the time you notice the absence of parts only while you are in the building process. It took me a lot of extra time, but I already calculated that in before starting the project.

Furthermore; Youtube appeared to be my friend in this project, since there are tons of instructional movies around to get information from. I was also lucky with my local bike shop to help me out with missing parts and giving good advice when I got stuck.

I did have play in the headset that made me worried, since I’ve seen some excellent Video’s from Patrick Lino (also known as patlien1 on this forum I believe) on Youtube. But in the end, it appeared a replacement of the inner lock end better montage. All in all, the integrated head set makes it trickier.
I did bring the bike in with my local bike shop once it was built for a good checkup and to micro adjust the shifters and to give myself some peace of mind about safety.

In conclusion; I learned a lot, will do many things differently in a new project. But it was very educational and a lot of fun, I think everybody can do it.
I did my first longer rides and I'm super happy with the end result. But I must say my only comparison of the ride quality is with my ancient aluminum road bike only on 23mm tires.

Re: FSA/Vision ACR Stem Users UNITE! Hi Pat,

I ran the FSA ACR headset on my TanTan TT-X21, which is a clone of the VB-099. I'm not sure what the differences are between any of these open mould frames that run 1.5" to 1.5" headsets, but I can tell you, though, that there were no major issues running the full FSA ACR headset, even with the ACR top cover if wanted to. I would have preferred to dump the open mould handlebars too, but I did recognize the issue with running cables and hydraulic hoses with a full FSA ACR system.

Just thinking out loud here, but it looks like FSA routes the front brake hose through the compression plug to deal with the space issues with running everything down the front of the head tube and around the steerer.  Other than space limitations, there's no inherent design reason why you couldn't try to cram everything down the front of the headtube, bypassing the compression plug route for the front hydraulic hose.

I don't think that would work too well, but if you are contemplating electronic shifting, especially SRAM, you could probably make it work. 

Do it Pat! Do it for us!!!!

Dark Tranquillity is here So, here is my version of VB-R-177.

Order placed in January, delayed by Chinese new year, procurement of spokes and hubs and a lockdown.

Custom paint and decals by Velobuild
Wheels are also from Velobuild (50mm), but customized with sapim CX ray spokes and Bitex 312 hubs
Groupset is all Shimano 105 hydraulic, with left crank PM (Xcadey)
Both rotors are SM-RT70-SS 140mm (also Shimano 105 series)
Tires are Conti GP5000 TL
Saddle is Selle Italia Flite FM Flow manganese rails

I didn't build it. I asked the LBS to do it for me as it would have taken ages to be completed
They didn't report issues in the compression bolt, but did report misalignment in the front wheel brake caliper too, as well as they said it was the "wrong rotor".  I fixed both things:
- I flipped the caliper mount as per Shimano manual
- When aligning the caliper, I used the business card method, but also inserted a 6mm allen key between the rotor (closer to the hub) and the caliper mount, before tighten the lower screw.  The one on top I left it at 6Nm.

Re: Velobuild VB-R-168 Frame
Quote from: patliean1 on April 27, 2022, 05:43:37 PM
Lateral stiffness is important because during a sprint, the wheels are no longer constantly vertical. So the force pushing the wheels can cause flex if the wheels aren't stiff laterally enough.

Imagine a wheel angled at 45 degrees, and the force from the cyclist pushing that wheel straight downward at 90 degrees.

This is true for rim brakes... but not for discs. A centerlock rotor only has a connection with the hub and so any deflection that causes brake rub would have to occour in the bearings or the hub shell which is unlikely to contribute much if anything. However, more likely it is the forks deflection during a sprint that is causing the brake rub.

However it is a general carbon road bike problem and not a chinese carbon frame problem as stated previously.

Re: Speeder SC-R48 Okay, so some interesting new discoveries:

There's this fully integrated SLC 2.0 using the Winspace Zero cockpit and this other example, both with the external brake holes still in place. I'm unsure if a hole had to be punched in the fork steerer or if the stock fork comes with provisions for external and internal routing to begin with.

Looking back at that fully integrated Adris Soar, the cockpit looked more like the Speeder SC-RH02 than the Winspace Zero. Where it gets interesting is that there may be more players in the Speeder/Winspace/Gotobike circle than I originally thought. The SC-RH02 cockpit looks the same as the Adapt AHD-01 and Edge Design HB-20 while the SC-R49D frame looks the same as the Adapt FM49-DB and Edge Design Aeolus.

Adapt also has frames that I couldn't find anywhere else like the AT-B01. They seem like a legit OEM supplier too as the Olympia Leader seems to be a rebrand of the FM08-DB frame.

And since Adapt states that the AHD-01 accepts fully integrated mechanical groupsets, the Speeder SC-R49D & SC-RH02 combo should be compatible too. All we need now is for Speeder to update the SC-R48D to work with that cockpit and we should be good.

RideNow TPU Just got the RideNow TPU inner tubes and a patch kit. They are light and very thin.  They have 65mm plastic stem.  Most debate has been over tpu use on rim brake wheels.  RideNow user manual refers to minimum tire size,thermal warnings, and safe use for rim brakes. 
The manual suggests to lower tire pressure as air and tarmac temps get high from morning to afternoon. They also ask that you lower pressure 20psi before long descents. They also ask you to take breaks on decents.

I bought them for my disc brake wheels so not really concerned. I also will be using as a spare on my road rides even for my rim wheels. There is so much saving you could be extra cautious and take 2 ridenow spares and still be half the storage needed as a latex or butyl tube.

My latex 156g + butyl spare 100=256g
RideNow  3x34g = 102g
Saving 154g

I'm watching for issues that have scared me away from TPUs in the past.  Hard to find leaks. Hard to patch or patch later failing.  Leaking around valve.  I'm being extra careful attaching the pump to the valve. I don't want the plastic stem to stretch and oval out.

Ah, you must not be American and/or not have a female in your home. Samantha Doll by American Girl

Ah!  From the video it looked like one of those old timey dolls that get possessed.
We’ve got a little female in our house.  She has Baby Alive. Also the creative source of the unicorn-theme of my bike. Lol

Re: Velobuild VB-R-177 Quick early review after 4 rides: 20, 30,45 and 100Kms, mostly to address current complaints here.

In the first ride, the seat was slipping and the front brake rubbing
I fixed both things (tighten the seat post and correcting the caliper position).  Both things seem still fine after those rides.

Bike feels very nice, Snappy under accelerations.
I seem to adapt very well to the position in this bike.  I don't find it overly aggressive, but this is probably given that I picked the bigger size.  I do notice the shorter reach.  Seamless transition to the narrower handlebar (400mm)

I don't perceive the headset play (roads here are horrendous).

I should also try to put the 11-28 cassette and keep the 11-32 for the gravel season or the odd Ardennes-like ride, because the bigger gap makes me either spinning or grinding

Wheelset from Velobuild (custom 50mm with Sapim and Bitex) feels OK. I was riding 42mm Prolite before and they catch more in crosswinds. In fact, I only perceive a bit of instability when a truck pass me, but nothing too dangerous

Re: Velobuild VB-R-177 Hello,
last year I built my first gravel bike velobuild GF-002, had some issues, most of them were due to my lack of enough experience and very easy to solve, and some were known velobuild issues, still relatively easy to solve.

I rode my bike over 3500 km.
My friends, after seeing me riding with confidence, also wanted to have a gravel bike like that, so I built another 7 GF-002 for friends, with integrated bar and separated bar and stem combinations, during that process, I learned lots of tricks, and made my tools better and collect a good amount of experience for building bikes.

I thought now it's time to build a proper road bike for myself again, and here it is, my new VB-R-177, and I absolutely love it.

The classic headset play problem can be solved (at least in my cases) with a sand paper, you should sand the steerer tube until the headcap sits perfectly on the compression plug, and yes, it should be straight, so take your time and try to have a clean cut, it helps.
If you still have problem, micro shims are your friend, cut one and put it between compression ring and headset cover.
For another classic problem, rubbing brakes, you should use M5 bolts that comes usually with break rotors(for 6 bolt rotors) as they are a bit shorter than regular bolts, they may help a lot to adjust the breaks properly.
Other than that, I don't see any major issue on velobuild side.

If you are considering some semi-hydraulic solution like juin-techs, you should not, yes, they can stop you, but the difference is like day and night, now I feel much much safer on descends, and have much better control overall.

For internal cable routing in handlebars, after testing the new method on a friends bike and saw the results, I did it for myself too, so here is how: just escape it, as easy as that :) you save yourself a good amount of time, and it gives you the possibility to change, bar or stem in future if you want to, I will post a picture so you can see what I did.

After about 200 km on this, I can say the ride quality is very good, the bike is very responsive, climbing and descending is very fun, the bike is fast and comfortable.

I did not build a weight weenie bike, so my setup with pedals, bottle cages, garmin mount and velobuild gravel wheels (which I used on my gravel bike) is 7.9, so you can cut some good amount of weight if you go for a lighter wheelset.

Re: Skywing Carbon - Anyone Heard of Them?

LoL has anyone else been harassed by them on Instagram yet? I think they've gone quiet.

I don’t think these guys are legitimate. Their third most recent IG pic is lifted from Builder Reserve who are one of the most high end Chinese cycling brands. They also lifted frame pics from Kung, a Chinese complete bike brand. At the end of the day, most of these anonymous “suppliers” are really just wholesale traders rather than actual OEM connected brands. If they weren’t selling bikes they’d be selling clothes or fashion accessories or whatever
