Re: Velobuild VB-R-218
I'm 235lbs i started high(100psi on 32mm gatorskin) and worked my way down. the high psi hand my back killing after 16 miles I'd be done. once i went below 80psi i could go all day long. i will never ride anything smaller then a 28 i love myself to much. unless its a short ride 10miles are less. I had 1 flat on my gp5000 on the rear and 3200 miles and non on the gator skins.
@madmax your street have to smoot a glass. i have to go thru 2.5 miles of cracked and bumpy road to get to the nearest 20 mile bike trail. an if I'm going to do anything longer the 25 mile that means I have to get back on our shit streets. An if your wondering I'm in the greater New Orleans, La area

110psi in a 32mm tire? Wow! That’s crazy high, IMO. I think I only ever used pressure that high in 23mm tires.
I use around 85-87psi in my tubulars (25 front / 28 rear) and even slightly less in my Corsa clinchers with latex tubes (25 front and rear, but 28 measured with) and I’m no flyweight at 82kg. The ride is fast and smooth.
I have no troubles averaging 20mph over long rides and I got all kinds of shit roads here, including cobbles.

Re: Velobuild VB-R-218 I’ve only used tubes and I thought about tubeless……briefly….after a few videos, it’s just too much hassle

Use a good thick tube and liner with gatorskin or tube and gp5000 and it should last a long time
The majority of flats come from incorrect psi, and your body weight pressing down on the tire and a bump will cause a pinch flat as you ride along.

I had really bad knee and back/sciatica pain that went away after I was fitted correctly and switched to a better saddle and shorts with better padding. Correct saddle height will fix a lot of the pain and this is one area where finding a good saddle brand that works for you is worth the money spent on it. I’m using the bontrager Aeolus comp saddle on all my bikes now

Re: Velobuild VB-R-218 I went from riding Canyon Endurace sl to riding this. My endurace is way more comfortable and i will use it for my 100 mile plus rides. The velobuild 218 is faster and takes less effort to hold speeds as it should since it is a aero bike. I had to change the wheels on the velobuild because the ride was way to harsh with hunt 48 limitless wheels. I don't really sprint much so I can't say much about it being sluggish.  I am 5'6" and around 200 pounds riding this frame and I enjoy it will probably enjoy it more when i lose 30 more pounds.

Re: Velobuild VB-R-218 Received my copy (Disc) on Monday and also ordered a set of RC-50 wheels. Complementing it with Rival AXS the assembly was straight forward, but some points one should take care of (if not already mentioned somewhere in this thread).

When you fit a DUB/30mm axle you have to file down a protruding rivet that holds the bottom battery cover. Otherwise, you can't mount the axle straight. Just remove the bottom cover and you can access the rivet. The BSA threads seem to be cut post-mold and co-axial alignment/facing is fine. I had to remove some residuary debris and paint, but then you can screw in the bottom-bracket by hand easily and crank-axle fits smooth. Break mounts seem not to be machined but are sufficiently flat/parallel - no rubbing. What you have to take care of is the thread-insert holding the rear axle. It is fixed with a small screw that may get loose/lost. It can then happen that the insert rotates, and the axle becomes loose. Coming from the factory without it (!) apply thread-lock to the screw and check regularly. Overall quality of the frame seems fine, but time will tell. Test-drive today did not reveal any issues. The frame feels firm and with 28mm/5bar sufficiently comfortable (for a race bike). The handlebar seemed quite flexible when putting power into the bike, but I have no experience with the original, so that might be normal.

Someone having long(er)-term experience?

Re: Velobuild VB-R-218 Now as for the frame that broke on me. I actually did a DIY repair that turned out to be pretty successful. I grew pretty tired of waiting as each of these frames takes at least three weeks to get to me so I decided to give it a try.

I attached pics from before and after the repair. I haven’t sanded and painted it yet as I wanted to wait and see if it holds up. What can I say? I’ve ridden around 400k and gave it some pretty hard abuse on well used cobbled roads in my area. And it held up fine. No seatpost slipping. No cracks. Nothing.

I would have never attempted this on more critical parts of the bike like handlebar or headtube. But it’s good to have learnt this skill for the future. I actually repaired a broken carbon bottle cage since. And that works fine, too.

Re: Velobuild VB-R-218 Hi VBR218 owners. On the edge of ordering a XXL frame. The geometry would be good for me. In fact, the dogma F is a relatively relaxed superbike geometry from my POV. The only thing that bothers me is the GC performance review on the fact that the frame would be stiff "vertically". I don't really care about the sluggish critic.

What do you think about that "vertically" stiff claim? Is it truly a back breaker?

How would you rate the comfort of the frame? Of course, wheel/tire setup affects that. What do you run for wheel/tires?

Re: Velobuild VB-R-218

This guy thinks it rides super comfy, for what it’s worth.
Also, GC Performance by his own admission pumps his tires up super hard.

I think it rides as firm as expected for an aero frame. Not as comfy as a traditional round tubed frame anyway. But by no means exceptionally harsh. I use Vittoria Corsa tubulars and Clinchers depending on the wheelset. Measured 28mm wide (25c labelled tires). It did not beat me up any more than my other bikes on longish 100km+ rides.

Re: Velobuild VB-R-218


yea i rounded them out real good. been trying to drill them out for when i find my final height.

Before you take to the drill, I’d try to gently tap in a slightly oversized torx bit with a hammer and see if you can turn it. That has worked for me a few times.

Re: Velobuild VB-R-218
Once again it’s good to see that VB at least stand behind their warranty.
But I must say, all the issues in this thread do not fill me with confidence. Not sure I would buy from VB again, to be honest.

The price is pretty good if you are building a bike for the first time on your own.
The bike itself rides quite well & is very light

These are the areas on which Velobuild should focus (IMO)  & I sent this to Chris as feedback

1. Adhesive bonds on the BB inserts.  If using Vibratite then let it cure for 3+ hours

2. No paint on threads  (BB & brake mounts)

3. Make sure mounts are faced correctly & the threads are chased

4. Correct sized bolts to be included with each order

5. No missing parts
