Ivan's V20C

I have hung up my Silvio 2.0 after 12 years and am now loving my V20c. I was fortunate to get the frameset (and wheels) second hand but basically brand new as someone else bought it as his first bent but never built it up, abandoning the idea of learning to ride the bike. Though my Silvio 2.0 (30 deg not 40 deg like S40) is similar, it still took me a few hundred kilometers to get as comfortable on it again. I will still cut about 4cm off the bar ends and shorten the brake cables but am already very happy with it. I won't go through the build just highlight a few choices that others may find useful.

GROUPSET: I purchased SRAM AXS Force 2 x 12 speed (e2) with 50-34 chainring and 10-34 cassette, 160mm cranks - all SRAM stock. It's been great with zero chain drops. I am happy with this gearing choice as I can leave it in the big chainring most of the time and ride the bike as a 1x. With the SRAM lever changing style, this is really nice. I wanted the lower range so I can load some luggage and take this touring (that will be a future post as I am planning this and figuring out my luggage setup now).

WHEELS: The wheels are Fulcrum 80mm but the previous owner had taken the decals off one so I had to do a full rebadging and decided I liked the silver grey of the ZIPP logos. I am using RideNow TPU tubes and purchased an inexpensive battery tire inflator. After doing some research I think I don't have to worry too much about the heat melting the plastic valve stems, especially if I give it a little cooling time and that only when I am inflating from a full flat.

HEADREST: I tried the suspension adjustable headrest but found what worked the best for me was to use the cushion from that attached directly to the stock headrest. I attached this with zip ties, which gives the right about of stability and movement. I also really like the minimal look as compared to the stock cushion. I would suggest that Cruzbike considers selling just the cushion for this purpose! Note that I am 173cm 5'7" and have my headrest adjusted such that it supports only the base of my skull. I never liked the stock headrest touching my neck.

LIGHT MOUNT: I was very pleased with how the light mount turned out. I have the Cruzbike light mount and stub but this is a much cleaner and more compact solution for me. I use lights with the Garmin mount so purchased an inexpensive mount signed to bolt onto a handlebar clamp from AliExpress (LINK HERE). Since Garmin mount devices must be rotated 90 deg this compact MagicShine Allty 400 is a perfect fit.

HYDRATION & REAR LIGHT: I don't see other riders use this setup but I have been very happy with it for the past 12 years on my Silvio and still adopt the same. These are Topeak CageMounts and Lezyne cages. The Topeak CageMounts position the cages just far back enough to clear the headrest. I use these specific cages as they have a horizontal piece over which my Cygolites can clip. I use a small ship on the Topeak Cagements to make my cages horizontal as the V20c headrest tubes are not vertical.

SADDLE BAG: The clearance is much tighter under the V20c so my previous saddle bag wouldn't fit. Another AliExpress purchase - Sahoo Saddle Bag - managed to fit. The key is holding it further up the headrest rails which I did some grippy straps. This took some fiddling before I found away so it would not slide down and touch the wheel.

INTERNAL CABLING WISH LIST: I do wonder why the V20c frame does not have internal cable routing hole for the rear brake to go into the head tube and come up where the front brake is routed. Just a slight change in the headset would make this possible and the cables cleaner without possibility of touching one's left leg.

Very nice bike, and you are right about the seat supporting the bottom of your head rather than your neck. This is the correct way to do, supporting the neck rather than the base of the skull can allow the head to bounce some given how heavy it is in relation to the muscles in your neck leading to nausea.

Thanks, Ivan, for the photos and all the information. I plan to assemble my V20c in the coming weeks, and this provides some good advice.

- Do you have a photo of your cockpit and how you mounted the GPS?

- For the bags, I was thinking of using Ortlieb Fork-Packs; they feature a mounting system with metal tabs.

I have one Ortlieb fork bag - wanted to try and install it behind the seat. The way the base is designed, I’m not sure it will fit the way you intend. I’d try to install it horizontally instead - that would be more aero.
Though I reckon for Vendettas the best option are Radical Banana paniers - as seen in Racer and L in this thread.

Interesting…I am also a gravel and bikepacking rider and have been planning on ways to carry my tent and luggage on my V20c for a tour (not off-road bikepacking of course!)

I considered the style that you are suggesting with fork bags. I think it will work with something like the Topeak Versamount and possibly a 3 bolt cage extender. But I decided this isn’t the way for me as I wanted larger carrying capacity for a tour.

Thus I have decided to go with rhe Aeroe Spider cradle and dry bag system with some modifications as the V20c seat stay width is about 50cm narrower than what the Aeroe Spider bars are designed for - MTB/gravel seat stays. Aeroe Spider has a front rack system that would be the correct width but the bar doesn’t appear to be long enough to clear the V20c rear wheel. Thus a custom bar solution is needed. I am still awaiting some parts for my test which I am confident this will work, giving me 2 x 12L storage. One could put smaller dry bags and have 2 x 8L storage so it has great flexibility!

Here are some mockups of the Aeroe Spider system with Moose Pack and Restrap Frame Bag 2.5L.

I believe this would have benefits over the Radical Banana bags as one can roll bags smaller, use different size bags and there is no movement of bags touching the frame. When unpacking the ability to take the whole bag off the bike into one’s room/tent is super helpful for touring. And the space for bottle cages under the seat would be available. I am excited to post this in a few weeks time if as this would be an alternative rack system for V20c allowing people to carry any 2 dry bags.

In addition, I use Restrap bags on my gravel bike and will use these on my V20c too. I will use my existing 0.8L top tube bag (under boom), the 2.5L frame bag (under frame) and the 10L handlebar barpack (custom bracket now to hold behind V20c headrest). Together with the Cruzbike Moose Pack this gives me 40L - which is more than I have with my gravel bike! Will post pictures of this setup if it works in a few weeks time.

Here is my cockpit as requested. I am using an Easton 70AX handlebar 44cm. It has a slight flare and as mentioned previously I will but cutting 4cm off the bar ends as I find them unnecessary and get in the way on very sharp turns. Zefal Spy mirrors are excellent. I ride in traffic in Singapore and find these great.

The Garmin mount is dead centre, very simple with 2 elastic bands and the mount sitting on the stem clamps. This is very neat as when on the bike all cables and mounts are hidden. The cables are still a few cm too long in this pic as I still want to some cable rerouting and micro adjustments.

Lots of good ideas, and thanks for the photos.

I also have the Aeroe rear-wheel setup on my daughter's bike; I'll give it a try, the spacing might be an issue.

What's the point of wrapping the entire handlebar? Do you place your hands on the tops of the bars?

I wrap the whole thing too. Two possibilities: 1) habit; 2) the bar tape comes packaged to do the whole thing.

Dunno, just always do and never really thought about stopping at the shifter.

But, but, but you could save 4g per side!
I’m a weight weenie first class with oak leaf clusters but have to say that’s a thought that’d never occurred to me. Sort of tangential to the topic but I saw a video a while back of a DF build that was just over 10 lbs. They used shifter cables for brake cables to save weight. Nuts!

In my case though the component with the biggest opportunity for weight savings is the one pushing the pedals –(

I only wrap the bar to hide the cables a little better. Perhaps when I cut them further I may wrap less…

That's a beautiful bike. Thanks for posting the pictures, and good luck with finding your own travel setup.

I found that Apidura bags work well under the seat when I need less luggage than the full capacity of the side panniers:

With this setup I have the 21l M5 Carbon Tailbag as a base. When I need more gear, such as for a 400 km brevet, I attach the front bag under the boom, and perhaps one Apidura bag under the seat.
For a 600 km Brevet where I bring gear to sleep outside, I attach three Apidura bags under the seat:

For even longer trips I'll then switch to the Radical Banana M side panniers, or the Banana Racer side panniers:
