Current Projects chat and miscellany

with reguards to Braker's big bike, is the main draw back with having such a large frame that it will flex more than a smaller frame? I'm sure i've seen somehwere a big bike with an extra tube (like on the back of a tandem, or on one of these kona's (not the best example).

if it's made of decent matieral would the added weight be worth it for added stiffness?

Short answer: all else being equal, larger frames will flex more (IIRC flexibility is an inverse square function of length - can't find the equation right now though but i'll look it up if anyone cares)

Longer answer: that question can't be answered with the information provided... flexibility is also directly proportional to EI (product of elastic modulus and moment of inertia) so it depends on the material and the tubing shape/ profile.

The sinner pista's going to be cool man, can't wait to see it built up

I understand exactly what you're doing, me and Marty, when desiging the GH2 discussed this for a while, and came up with the conc that 26 + 2" tyres roughly = 700c
but you have to have wider spaced forks and stays, to accomodate tyre width.
good luck bro, lets see some finished photos.

yes, width is where it hurts. even tried putting 1.37, but it would take out the paint little by little!

I hope to be able to put the photos soon. the base color layer is quite thick because I wanted it to be able to absorb small nicks. the problem is that now it does not want to harden, and I'm sure I will ruin the paint on the dropouts if paint is not hardened enough. it's so hard to wait now that it is almost done!

it has 'viscount' stamped on the top of the seat stays but have never heard much about them. got a chrome rear triangle and chrome forks, the forks are quite beefy too. and it's quite tight but not overly so.

Cool sounds nice, but nah still too small :-(

I have Phils on my Bianchi, how it's not a good frame?

And I have Phils on my Steamroller. I also agree with the other stuff you said Ed, but can definitely see where Harry is coming from.

Partridge in the same way he says "this country..."

Repped.

Current incarnation of the Dave, image seems to have lost a lot of quality:

Paint looks so nice.

It has a lovely sparkle in the sun.

New frame. No indication of whoever made it. No serial number or anything.
Has been resprayed at some point with name of a local bike shop.
Columbus stamped fork ends. Oval tubes.
Maybe a long shot but any ideas on tubeset, origins etc.?

Holy shit that's wonderful. The way the lug lines just flow in to the "gussets". FIT.

I demand larger closeups for the porn thread.

+1. Very interesting head cluster.

lovely frame, want to see some close-ups too.

Nice, I like it! Not as keen on the fork crown though :/

Still, it's something different and it looks great.

Maybe a long shot but any ideas on tubeset, origins etc.?

Columbus MAX

Famously used on Eddy Merckx MX-Leader frames.

Ultra stiff by design.

Here's the MXL interpretation.

Thank you kindly.
MAX was what i thought initially from googling the charareristics, but I'm no expert.

so so nice

it looks alot like this:

according to this ebay-sale it's a zullo

Finally finished my Bob Jackson after the hassle of it arriving scratched. Went for a test ride and it rides well. Feels a bit stretched so will be on the lookout for a shorter stem. Any recommendations?

It is actually green, but due to my camera (phone) being crap it looks black. I have a decent camera on the Christmas list!

yep, try something like these:

Right, going for the FSA bars. Not sure if I should go for 40 or 42cm. The track bars I have on there are 40cm. Anyone recommend I should go for 40 or 42cm?

Also I will be reducing the steerer/stack heigh by around 20mm or so. And then fitting a shorter stem, current is 130mm. Think 110mm would be better, agreed?

Some more bar tape and I should be sorted.

Thanks for the advice.

Currently its like this:

my recommendation is to try and match the handlebar width to your shoulder width.

if you find 130mm too long, i.e. find yourself sliding forward/arm overstretched, 110mm should do the trick, but worth going to a reputable bike shop and ask to try out different stem length before you buy, worth experimenting.

My project nearing completion :

1952 Claud Butler Jubilee

/attachments/17694

Forks back from re-chroming last week.
Frame blast cleaned. Now got to paint it.
NOS 27" rims, Cinelli stem, North Road bars upside down.
Tange H/set, machined crown bearing to fit 27.4
Rode it for couple of months in the summer, with gearing at 39x17 (39 is inner ring from a Shimano double set up, used on the outer ring position) and I am a virgin fixed gear rider.
Rode very nicely. Now in pieces for painting.

You must be on the large side looking at the size of the bike so I would guess that 44 bars would be nearer the correct width. As Ed suggests, match them to shoulder width for best fit generally.

Not fixed or SS, but well happy with this as my entrant and real contender for Bromptons Anti-Porn of the Year award.

nothing wrong with slightly wider bars -- I usually go a bit wider over my shoulder width. more comfort, more room, more leverage, chest is not constructed so easier breathing.

This is going to Vaz tomorrow for a nip and tuck... Let's see how she responds to treatment, there are some issues... My planned winter beater, an old Holdsworth Zephyr...

Liking it, Joe...
