Opinions on Saturn Sewup Rims
I just acquired a pair of NOS Saturn HT-C21 sewup rims. Does anyone here
know about these rims? They're made in Italy and were supposedly used by the US Olympic team in 1984. Chas. |

Not a great answer for your specific question, but my only clincher front wheel is a Saturn HC-19 on a Dura-Ace hub from 1985 that is still going strong although it, admittedly, gets little use other than on the trainer during the winter. -Mike |

The importer changed the name to 'Saturae' as the auto company's use was prior to his use. One of the TM areas is 'transportation' so we group with cars and Harleys and Boeing. -- Andrew Muzi www.yellowjersey.org/ Open every day since 1 April, 1971 |

Staurae Tubular Rims HT-C21 22mm wide 470g HT-S20 20mm wide 410g HT-R19 19mm wide 340g Staurae Clincher Rims HC19 19mm wide 400g At 470g the HT-C21 sort of defeats the purpose of riding tubulars except maybe cyclo-cross.

Super tough, laced on 14gauge x 36 with a 22-23mm tub. G'wan, say over here what you said over on urc about what to do with the spokes, I dare you :-) The Saturne rim is extremely stiff for its section, 20x12mm, being about 18oz Made up with heavy spokes as I have done makes it unnecessary/ undesirable (and hard work) to tie up the spokes as the structure is so rigid. I didn't. The Saturne rim will not benefit from the expense of lighter butted spookes. If 15 gauge were available at the same minimal cost, I'd have used them on appearance alone. Spoke position is important, the use of fewer crossings reduces the angle between the inner spoke and the hub flange. Tie-ing at the second cross(away from rim) pulls the inner spoke towards the flange. Both transfer pulling of the head to pulling on the bend, most desirable. Tie-ing at the second cross reduces the rocking angle of the spoke by bracing with another spoke pair, extending the life of the spoke before fatigue failure on the bend. Greater crossings also reduce the rocking angle by taking the first crossing further along the spoke towards the rim as when spokes are left untied. Applicable to all woven spokes is the correction at the first crossing to remove the bow in the spokes by bending them here during fitting so that they may rest in the same position with zero tension as with excess tension. |
