Subject: Re: [CR]tensionometers


I find the tensionmeter useful in determining if the spokes are at the right tension for particular guages or styles of spokes. To determine if all the spokes have even tension I spin the wheel and as long as the spot where the spokes cross doesn't move up or down all the spokes are even tension, doesn't work with straight pull.

\r?\n>I will!!!!!!!!!

\r?\n>From what I understand, just as Bobby Richardson

\r?\n>of the old N.Y. Yankess did, I will be batting second

\r?\n>4) Which is better, Masi OR Flying Scot?

\r?\n> (can't do. there will be brits present)

\r?\n>5) Frame 'brand' licensing: Good or bad?

\r?\n> (can linens and perfumes be the next step

\r?\n>

\r?\n>...I've decided that the subject will be my area of expertise:

\r?\n> *My Life So Far*

\r?\n><><><><><><><><><><><><>

\r?\n>Here are a few things I will be bringing for the

\r?\n>show n' tell hour:

\r?\n>1) The twins, a.k.a. my two 1971 Italian Masi

\r?\n> Gran Criteriums, as described in these two links:

\r?\n>http://www.richardsachs.com/articles/rsachsperiod.html

\r?\n>http://www.campyonly.com/retrobikes/sachs_masi.html

\r?\n>2) A 1999 25th Anniversary Replica Model Bicycle.

\r?\n>3) A lovely 'preserved' example of a simple but bitchin'

\r?\n> frame I built in 1991, pictured here:

\r?\n>http://www.richardsachs.com/gallery/pages/rsbluehtube.htm

\r?\n>4) My newest personal bicycle, built since my last newest

\r?\n> personal bicycle was TOTALED during the recent

\r?\n> unpleasantness of late January.

\r?\n>5) A frame in the half-built stages, to be displayed,

\r?\n> Mario-style, in a vintage Campagnolo workstand.

\r?\n>6) A collection of 40+ sets (of three) lugs from the

\r?\n> 50's to the 90's to show those of you who don't

\r?\n> build the frames just what these bad boys look like

\r?\n> in their 'rough' state!

\r?\n>7) Two 4 minute films produced and aired on local

\r?\n> television by the NBC and CBS affiliates. One clip

\r?\n> is from last summer, the other is from '89. (I'm ready

\r?\n> for my close-up, Mr. DeMille).

\r?\n>8) My collection of nearly ONE HUNDRED New Yorker

\r?\n> magazines, from the 20's to the present, each and every

\r?\n> f?cking one of them depicting a bicycle in the cover art

\r?\n> in some way, shape, or form. These treasures are kept

\r?\n> in archival bags. But no matter, if you sneeze within

\r?\n> 100 feet of them, you'll be on my shit list. These things

\r?\n> are the only 'things' more important to me than my

\r?\n> butler building full of nos/nip campy, oops, I mean

\r?\n> 'Campagnolo'.

\r?\n>9) The Pista Resistance, perhaps 'A(nother) Resurrection of

\r?\n> Highest Order', the bicycle that took 30 years to build,

\r?\n> the frame into which all my knowledge, every mistake,

\r?\n> each innovation, every kilometer raced, every lie I ever told,

\r?\n> every frame I ever copied from... yada, yada, yada.

\r?\n> The International, make that the Galactic debut of the

\r?\n> Richard Sachs 30th Anniversary frame built up as a complete

\r?\n> bicycle. Preview pics of the frame are here:

\r?\n>http://www.richardsachs.com/rsachs30gallery/index.htm

\r?\n>10) And if time permits, I'll talk about,

\r?\n> a) why red Twizzlers are my favorite food,

\r?\n> b) why my favorite scent is fabric softener,

\r?\n> c) why the stripes on my ties MUST descend from the heart

\r?\n> rather than the 'wrong' way,

\r?\n> d) why "someone has to win the race, it might as well be me",

\r?\n> e) why Varttina is my favorite band,

\r?\n> f) why 'Ghost World' is now my favorite movie,

\r?\n> g) why...

\r?\n>

\r?\n>And most importantly!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

\r?\n>I will be AUCTIONING off three NEW OLD STOCK, never

\r?\n>been read, never been opened, completely sans dna

\r?\n>copies of the June 1990 Bicycle Guide issue outing my

\r?\n>IMPORTANT: All revenue derived from the high bids will

\r?\n>Subject: re: [CR]Hi-E Help??

\r?\n>

\r?\n>Eric Elman wrote with notes and questions on Hi-E hubs. I like them, but

\r?\n>they are not w/o "idiosyncracies." Let me see if I can help with his

\r?\n>questions.

\r?\n>Eric's description:

\r?\n>Front: low flange, all silver flanges and center, "Hi-E" etched in center,

\r?\n>16h per side.

\r?\n>Rear: High flange (almost 3"), all silver flanges and center with "Hi-E"

\r?\n>etched in center, threaded for a freewheel, 126mm, 24h on drove side and 16h

\r?\n>on other.

\r?\n>

\r?\n>EE: So, are these early hubs or recent hubs, about what year? I've seen a set

\r?\n>with black centers so assume thses are older?

\r?\n>HS: I assume earlier. I have some from the 1970s, but the 126 is slightly

\r?\n>later than the 120s we have, I'm sure. I've never seen black centers.

\r?\n>

\r?\n>EE: Is the hi-flange rear uncommon as I've never seen another?

\r?\n>HS: I don't recall ever seeing either a low-flange rear or a hi-flange front.

\r?\n>

\r?\n>EE: Why a hi-flange rear and low front?

\r?\n>HS: No torque on front wheel, Harlan Meyer (designer/owner) advocated

\r?\n>radial fronts. Thought - I gues, that HF gave better ability to transfer

\r?\n>torque in the back.

\r?\n>

\r?\n>EE: Why 16/24h on the rear and how would that be laced up to a 40h rim?

\r?\n>HS: 16/24 was designed to get even spoke tension, given dishing that

\r?\n>increases tension on drive side. Use 16 radials on left, and 24 on the

\r?\n>right. Ah, more subtlety: Use 4x length spokes for "pulling"

\r?\n>(counterclockwise direction from hub to rim) and 2x length for "static" spokes.

\r?\n>

\r?\n>EE: These are very light - are they durable and good to use for an

\r?\n>everyday bike

\r?\n>or are do they lack durability and should only be used for races?

\r?\n>HS: There were two different front hubs (at least). Front barrel <20 mm

\r?\n>diameter is the "time trial" hub, recommended for lighter riders. My wife

\r?\n>used hers (with superlight rims) routinely for years till she stopped

\r?\n>riding except the tandem.

\r?\n>

\r?\n>EE: How do/did they compare on cost & quality to say Phil hubs and campagnolo

\r?\n>Record?

\r?\n>HS: Your HiE hubs have one weirdness about them. Like Phil, they use

\r?\n>cartridge bearings. Unlike Phil, you have to unlace the wheel to pull the

\r?\n>end cap/flange to replace the bearing, if it ever fails. I've never had to

\r?\n>replace one, but don't have near the mileage on them that we have on some

\r?\n>Phils.

\r?\n>

\r?\n>As for quality, leaving artistry out of it, and being a bit heretical, the

\r?\n>Campy Record hub is a fine example of great 1920s design. Great races,

\r?\n>great finish, fine angled flanges and countersunk holes. Phil and HiE are,

\r?\n>in my opinion, much better hubs. Larger diameter axle for more stiffness

\r?\n>and potential for less weight, cartridge bearings for long life and good

\r?\n>performance, and equally good or better spoke seating.

\r?\n>

\r?\n>Seeing as they are so obsolete and hard to work on, I would be willing to

\r?\n>trade something of equivalent value, perhaps some Normandy sports... :-)

\r?\n>I will second this. "Trueness" and maintaining true are dependent on equal

\r?\n>tension. Joe Young http://www.youngwheels.com by all accounts is considered the

\r?\n>premier wheel builder in this country. His resume reads like the

\r?\n>reincarnation of Spence Wolf. Anyways, Joe insists that equal and maximum

\r?\n>tension are the two critical factors in wheelbuilding, and wheels that he

\r?\n>has built for me over the decades have NEVER gone out of true, and (call me

\r?\n>crazy because I cannot quantify why) but they are also very fast. Joe adds

\r?\n>some other details to his work - things that score high points for me -

\r?\n>

\r?\n>1) Center punch the spoke heads to "set" them in the hub flanges. This

\r?\n>technique prevents spoke head "creep" that can effect trueness and tension.

\r?\n>

\r?\n>2) On a completed wheel the decals should read from the drive side of the

\r?\n>bike, with the hub spindle markings read from the saddle looking foreward,

\r?\n>directly through the valve hole. For example, say you have a Campagnolo hub

\r?\n>and fiamme rim. With the wheel in a truing stand, spin the wheel so that the

\r?\n>valve hole is up (at the 12:00 position). Looking through the valve hole,

\r?\n>standing behind the wheel, the Campagnolo script on the hub spindle should

\r?\n>be facing you rightside up, also at the 12:00 position, and the rim decal

\r?\n>directly beyond, at the 6:00 position. Technically speaking, it doesn't make

\r?\n>a difference, but aesthetically it make sense.

\r?\n>

\r?\n>3) The issue of locktite is always debated, but Joe does not use it and

\r?\n>claims that a properly tensioned spoke will not loosen. I can attest to his

\r?\n>theory, as none of his spokes have ever loosened on me.
