Vendetta build

[Jim Gerwing]

I received my new vendetta frame about three weeks ago but I don't have it on the road just yet. I haven't posted for a bit and I feel like I'm getting dropped by Eric's great posts. I should be on the road in about a week so I can confirm everything Eric is saying.
having spent about 3 months on the Quest/rollers, I took the Quest on to a nearby country road. Within about 100 metres it was clear to me that I needed some parking lot work before being road worthy.

Congratulations on your new

Congratulations on your new Vendetta. Pictures always speak! Post some here and it will get us all talking pretty quick!

Hi Jim, I think you will find

Hi Jim, I think you will find the Vendetta likes to drop others. It is a beast that hungers for the thrill of victory - you have been warned!

Jim's V2 on the road

Okay, I'm on the road with the V2. My goal this year is to beat my personal best one hour time trial which I set last year on a DF (41.5km/hr average speed). I have my own set of rules: flying start, start line is finish line, out and back with a safe turn around which means I stop the clock at the furthest point out (20km) and give myself a flying restart on the return leg. Record setting evenings have negligible wind and I have, close to me, a reasonably flat course which could be flatter.
Here are my last three 'trials': Quest 13km/24:42=31.6km/hr, Quest 13km/24:20=32.1km/hr and V2 13km/23:00=33.9km/hr
The bike is not picture perfect yet. I'm running mismatched tires which I want to match with coordinated bar tape that compliments my favorite clothing (red).
I need to find 8km/hr and extend it roughly three times my initial runs.
I'm not clipped in yet.
I'm not optimizing gear selection yet.
the bike needs tuning (rear disc brake is dragging slightly).
Early season on new kind of bike on which I expect to become more skilled and get in better shape to take advantage of aerodynamic potentials.

Early pics

There are a few things that I want to do in order to optimize my V. Nevertheless, here are some early pics.

I see you have mounted disc

I see you have mounted disc brakes did you use Avid BB7?
It's a nice option being able to mount disc brakes.

I hope you will enjoy your new Vendetta with very good brakes.

 

[Jim Gerwing]

Avid bb7

Yes, Avid BB7's otherwise I have Shimano 105's or ultegra components. I want to put red tires and bar tape on. Right now I'm just learning how to ride.
Cheers,

Jim

Hmmm, based on those pictures

Hmmm, based on those pictures your fast speeds look like they are due at least somewhat to the antigravity effect in your neighborhood.

Sorry Jim, coudn't resist.
So

Sorry Jim, coudn't resist.

So where did your source your road disc wheelset from? I had been thinking about disc brakes but haven't bothered yet since I had already bought the Rival road brakes.

Did you run into any fitment issues with the discs or did everything go together without any problem?

[Jim Gerwing]

The wheel deal

My original plan was to cannibalize my Ultegra equipped DF but I didn't like the way parts were fitting so I abandoned that idea for the LBS. Specifically, I didn't like the way the front caliper brake scraped on my right leg which meant going with a disc brake which meant going with an hybrid wheel (Shimano HB M525A hub with Mavic A119 rims) that would accept a disc. Apparently, soon the UCI is changing the rules to allow disc brakes on road bikes and that should open things up for production road bike wheel sets. My guy at the LBS recommended the BB7's over the BB5's because, he said, the lever action is shorter. whether this is true or not, I don't know, in any event the cost difference was not prohibitive. The only problem so far has been the rear disc rubbing slightly which was easily fixed by raising the caliper housing with thicker washers. As well, the rear disc rotates very close to the lower stay which, again, is judiciously cleared with an appropriate amount of washers.

The Quest has BB5s and I

The Quest has BB5s and I could adjust them with no rub and very, very short lever action. I followed the advice of others and used a business card between the brake pad and the disk when setting them up which took care of both the rub and made the lever action very short.

Unlike the BB7s, only one side of the BB5 has the adjustable pad. The other side you adjust at the caliper mount with what looks like eccentric washers to me. I actually found them very easy to adjust once I learned of the business card trick.

Hi Jim
Like your build. I had

Hi Jim

Like your build. I had the same question for you as Eric had, but he beat me to it.

The BB7s look great on your bike. Can you tell us a little about the feel of them on the road - specifically how you've found them in terms of both power and modulation. And what size discs are you running? Most moving to road discs are suggesting 160mm front and 140mm back.

I've run a BB7 on the rear wheel of my Volae Club for the past 8 years. Best decision I made on the bike - it made a massive difference to braking ability. I'm considering a Vendetta build using Ultegra Di2 and the new TRP HY-RD disc brakes.

Kind regards.... Blair

How much did you trim off

How much did you trim off your slider? It looks like yours is further inside the boom than mine.

You ordered the medium frame?

As you ride it, I recommend you take a sharper and draw a line on the top of the slider for where you have it fitted. I've found that as I ride and really apply power mashing up a hill or just mashing period instead of spinning the slider pulls out about 1/8 to 1/4 of an inch even with the boom clamp really tight.

Feels OK to me when I'm riding it as I have been forgetting to check so it doesn't seem to be introducing any strain in my body. I also marked where it has been ending up and it doesn't seem to be moving any further so I may just consider it an automatic x-seam adjuster and just check it periodically for any further movement.

So far the difference has been slight enough it doesn't seem to have affected the FD, or perhaps made it shift a bit better based on how I currently have it adjusted.

Dear Blair and Eric:

I think I have the picture issue figured out.
Blair: 140mm disc on back and 160mm on front.
The front brake is now beginning to drag a bit. Apparently, this is normal for new disc brakes.
As for 'modulation', I cannot intelligently respond except to say I do not want to hear them when I'm trying to go fast.
The drive hub is Shimano FH M525A and along with the non-drive hub (HB M525A), they do not get good reviews on the web.
Eric: as per your modification with John's consent, I removed 10cm of steering tube and went with near maximum insertion.
On my first shake down ride I, like you, mashed, and I had about 4cm of separation. I have it well torqued now and I'll keep an eye on it.
I have added clippless pedals and have had a few short sessions in the parking lot and around the block. Weather permitting I'll make a longer run tonight, taking it fairly easy, though, I think that I injured my left hamstring getting off the V. (Getting on and off the V gracefully and efficiently might make a good training video)

Allez, Allez, Allez, V, V, V.
