The Silca TRUTH Pressure Gauge, originally hand-built by Josh Poertner himself, lives up to its name by giving highly accurate and repeatable pressure readings. That's because this USA-made digital gauge not only compensates for temperature and humidity, but also eliminates the parallax error common to analogue readings. Its four-digit display and calibration to 30 psi lead to a guaranteed accuracy of 0.2% at 0-60 psi and 0.5% at 100 psi.Featuring a 3D printed titanium body, a medical grade stainless steel connection, a protective silicone rubber housing and a valve connection port that uses a Silca 252 Chuck, the TRUTH Gauge requires minimal air to activate and only loses 0.1 psi per reading in a 25mm tyre at 100 psi, making it far more efficient than competitor designs.Run on a 9V battery that gives an impressive 1,200 hours of battery life, the easy-to-use gauge has proven its stripes with more than a 100 WorldTour Victories and five Paris Roubaix wins since 2010, making it a must-have for serious racers and casual riders alike.Key features:Digital pressure gauge,Precise +/- 1% full scale accuracy at 200 psi,Compensates for temperature and humidity,Connection made from 316L stainless steel,6AL/4V 3D printed titanium body and airway,Aluminium twist-style bleed valve,High impact silicone rubber protective housing,Auto shut-off after 20 minutes, 1,200-hour battery life,9V battery included but not connected,Weight 221g,Presta compatible only,Made in the USA.
Since 1917 all Silca pumps have used steam pressure-formed leather cup washers to achieve high pressures. The 731 (formally 73.1) is the classic 28mm diameter washer used on pumps produced between 1917 and 2008. In 2008, Pista and SuperPista pumps moved from steel barrels with 28mm inner diameter, to aluminium barrels with 30mm diameter. The 741 (formally 74.1) Leather Washer fits all 2008 and later pumps with 30mm inner diameter.Since the 1960's all SILCA leather washers have come from the same leather converting house in the fashion district of Milan, Italy. For more than 5 decades the same supplier has cut these washers from the excess material left over from the production of exotic handbags, Italian luxury cars interiors, and high-fashion luggage. A small press is used to hand cut and then pressure form these washers from pieces of leather otherwise sent to the trash. Silca receives these parts by the hundred and it is always fun to sift through them looking at the various finishes and textures while thinking about the exotic sports car interior, $2000 briefcase, or handcrafted luggage sets from which they share history.From a purely functional standpoint, inexpensive o-rings are most commonly used in this application, but no o-ring can match the smooth feel and zero-stiction action of a leather gasket. It is common today to find Silca leather gasket pumps throughout the professional peloton (especially during the spring classics) as o-ring seal pumps struggle with heat and often are unable to seal once the pump barrel is hot from inflating more than a few wheels.Key Features731 Fits 28mm internal diameter Pista and Super Pista pumps (pre-2008),741 Fits 30mm internal diameter Pista and Super Pista pumps (post-2008),Made from finest quality full grain leather,Produced by hand on the same equipment continuously since 1960,NEW!
