LooOOOook 464 Dreadnought Tank

I've had this for over 3 years, but in that time it has only been to Calshot once, Palmer Park two or three times and round a couple of 10 mile TT courses with a front brake hanging off the fork, so its currency might seem a bit dubious. However, with the Prigledrome opening next year, the time has come to clean the gathered dust off it and start putting in some laps.

Here we see it as first built:

(OSCC)

The Ellipses were lovely but are long gone, sold to make room for something built onto the 24h One-One/Novatecs which have lain unlaced for 18 months now. Arrived in the post this morning are Halo Calibre (aka Kinlin XR380) rims, which will do for most purposes, and maintain the Dreadnought Tank theme, although a guide to why the Ellipses are so tough is that even with large flanges, 4 more spokes per wheel and an extra 8mm of rim depth, the wheels should actually be lighter than before. If it turns out that tubs are mandatory at the Pringle, I'll knock up some Kinlin TB25 to Novatec for indoors. Even with sprints and tubs, this thing will still be heavier than my road bike.

Other problems to be solved:

1. They might insist, in the face of all appeals to trigonometry, on 165mm cranks, and the current UltraTorque Pista set up is 170mm
   
2. The chainline on the Novatecs is ~42mm, but the chainline at the front is ~46mm to match Ellipses and Fixxers.
   

Y U no 23mm rim? 20c tyres?

22mm Veloflex Corsa, wanted reasonably deep rims due to low spoke count and high rider mass, the only option without going crabon would have been H+Son Eero 48s laced to half the holes. It's a play bike, not a race bike, so ultimate performance isn't such a big deal. The Halo/Kinlin is about a pound lighter for a pair, so probably not much in it in a sprint :-)

Despite following the link, I still don't get the reference.

(unless you're talking about the rims in which case I have no idea?)

It's a Whyte notation gag, bound to be lost on any young or foreign readers.

Gotcha!

Well almost: how does your choice of rim maintain the theme, if the gag relates to the name of the frame?

I only ask on behalf of my young, foreign scullery maid.

Both Dreadnought and Tank reference heavy things; Kinlin XR380s are 550g a piece, so hardly a weight weenie choice.

Another way to do train stuff is by using UIC categorisation, sadly not UCI. Do ALL the train stuff!

Speaking of which, has anybody heard of any scrutineering trouble with the 464, or is it the case that nobody gets exposed to that level of scrutineering unless they are good enough to be on a better bike? I'm pretty sure a really picky commissaire would object to the fork blades being over 3:1 aspect ratio.

Why dreadnought with bogey config?

Ignore the slack chain, I'll sort that out when I haz chainring bolt spacers and the right size sprocket.

FC-5700 cranks, Stronglight 48T track ring which is literally half the weight of the 49T Goldtec. Chainring bolts and HT2 preload bolt are from Beyondcomponents who gain Tester Approved status for reasonably priced and in stock chainring bolts with Allen key fitting both sides.

I eventually decided to stick with the 46mm chainline to keep wheel interchangeability with my TT bike, so I'm going to move the rear hub sideways to match, resulting in a rear wheel with 'negative' dish.

What's the chain line if you mount the ring on the inner of the arms?

About 39mm with a thick track ring.

'negative' dish.

How does that interface with an inverse shim?

I need to make an inverse shim to go between the drive side lock nuts

What chain tugs do you use and why did you choose a different/non-Shimano preload bolt?

FireEye tugs

Aluminium preload bolt because I already own a 10mm Allen key, so it was either a bling bolt (£3.49 posted) or buy the Shimano or equivalent tool for the horrible plastic bolt (£3.19 posted). On that calculation, it's 30p well spent :-)

Cheers.

Both rims seemed to have different measurement (Halo's heavier, 1mm wider etc.) the only similarity is the depth, simple manufacturer measurement error?

Yes, just something lost in translation.

Never mind this, where's the tandem?

How come you had them anodised? Did you do the rims?

The rims were already black anodised, wanted the hubs to match. It was cheaper to buy hubs from Planet X and get them anodised than to get black ones from any other seller.

Tandem is in its own thread, will update there when I have something to show.
