Tifosi CK7 Questions

[Micheal Ra]

I'm interested in a Tifosi CK7 and have a couple of questions.

How stiff are the frames? The reason I ask is that my 2002 Dawes
Chilliwack (a 7005-T6 affair with a top-tube slope similar to that of
the 2004 Giant TCR/OCR frames) can show disconcerting amount lot of
sideways movement at the bottom bracket under load. I'm not
particularly heavy for my height (12st 7lbs at 6'2") and spin at a
cadence of around 95 rather than mashing big gears. With a 35" inseam
I guess I'd need the largest frame size. Does anybody have this size
frame in the Tifosi? Does it flex much?

What are the cassette and chainring sizes for the 10sp Veloce? I
would guess something like 12-26 or 13-26 and 52/42/30 or 52/40/30.
However I can't find much information on the Web about Campagnolo
sizes. (Sheldon's wonderful for Shimano, but there appears to be no
equivalent source for Campagnolo.)

Thanks in advance,
Mr. Chilliwack

Uhhhhmmmm... Campagnolo?

As to what it 'comes with', this is Campagnolo, not some cheapjack far
eastern outfit. It comes with what you specify. 13-26 is not unusual
but 12-23, 12-25, 13-26, 13-29, 14-23 are all standard. At the front,
39-53, 42-52 (doubles) or 30-42-52 (triple) are standard.

I don't understandyour point. It's perfectly easy to specify Shimano
drivetrains.

Except thatr the cheapjack far eastern outfit will do cranks in a sensible
length for short people like me (as do the french lot who also will do
compact double).

And 30-40-50 triple, which I've always felt is an excellent choice.

Good choice sir. I have one as well

Stiff. It's overbuilt Al. Granted, I'm not heavy, but it is solid

I have the "L" rather than the XL and I'm 6' 1" with and take 34" leg
trousers if that's any help.

I'd say you'll be on the join between the two. If you have a long torso
or like the bars quite high, go for the larger. When I ordered mine
(via my LBS) they rang Tifosi up and said "we want a bike for a customer
who is 6' 1" and lanky, what size should we get" and the guy at the
other end said "sounds like me, get a L not a XL". Service.

Gearing wise, I'd go for 30/40/50 triple 175mm cranks and a 12-25 or
13-26 block.

Veloce triple chainset is always supplied with 30-42-52, but it's
reasonable to sell the rings* and replace them (with Campag or TA) if you
like. I suggest 28/40/50 or 26/39/50 if you want lower gears. Ideally
the middle ring should be a pinned middle-specific version but double
inner rings do work(albeit with slower shifting). Get 175mm cranks.

10sp cassettes: 12-23, 12-25, 13-26, 13-29, 14-23.

* or get supplier to do this as it'll save you removing crank to change
inner ring

But would have to change the rings or go up to Centaur to get it.

A 28T or smaller granny would be even better if the bottom gear is more of
a priority than smooth shifting.

I was seeing who I could tempt over the bridge.

The Conservative Party now has the support of a smaller proportion of
the electorate in Scotland than Sinn Fein have in Northern Ireland.

I have the CK4. I am the same height as you and a few pounds lighter. I
bought the large (L) size after discussing it with the shop staff. It feels
right for me.

I'm not sure about flex at the BB - how can I tell?

You have a much longer inseam than I have. I'm 32" and I use 170mm cranks. I
have heard that you should use shorter cranks if you like to spin or have
knee trouble, longer if you like to mash. Arthur's advice sounds right.

Tom.

Find a straight bit of road, look down at BB, accelerate like mad.

Is this a good idea?

At least you won't know what hit you.

I did a couple of sprints this morning on the CK4. If a slight chain rub on
the front mech in top which becomes a major chain rub when sprinting is a
sign of frame flex then the frame does flex. A fair bit would guess.

Tom.

(NB I kept my head up the whole time.)

This rub is more likely the result of the BB spindle flexing than the
frame. Especially if it happens (as it usually does) on the right
downstroke and not the left.

Is that a sign of a cheap BB spindle, or do they all flex a significant
amount?

Can also be the crank/spider assembly flexing, particularly on cheap
cranksets with pressed steel spiders. My Raleigh Record Sprint has such
a thing...

Shouldn't normally be enough to worry about, but it's not uncommon for
even good frames/spindles/cranks/spiders to flex enough to cause rubbing
if the mech is adjusted with hardly any clearance. I don't think it's a
particularly good way to judge stiffness.

You could casually test total stiffness by standing besides bike (facing
the side of bike) and forcing flex via the pedal.

....locate parked vehicle.

I've seen this done (Or rather, I heard the tale and saw the aftermath).
I wouldn't recommend it.

How about; Find a straight bit of road, get mate to ride behind and look
at your BB, accelerate like mad.
