We can only guess what C.A.E. Stands for. The 1890’s, just like the 1990’s, was a boom period for bicycles and for the companies that made them. Manufacturers sprung up overnight and disappeared just as quickly the next day

museum bicycles from 1875 to 1944 | classic cycle

A huge portion of the bicycles that were being built during the 1890’s came out of Ohio. The Wright Brothers and Huffman bikes were located in Dayton. Miami Cycle manufacturing was in Middleton. Fisher Mfg., Hanauer & Brothers, Evans, and Schleuter Cycles were all made in Cincinnati. Shelby steel tubing came out of Shelby, Ohio. Columbus bicycles from Columbus. Hercules bicycles (not to be confused with the English Hercules brand of the 20th century) made their bikes in Cleveland. Cleveland bicycles? They actually came out of Toledo

This bike is in remarkably good condition for its age. The clincher style wooden rims and Goodyear tires appear to be original, and not only do the tubes still hold air, everything tolerated a recent (careful) ride around the neighborhood. If the Goodyear tires are in fact original, then they would have been from the first year that tires rolled out of the Akron plant

The handlebar is a Kelly Adjustable model. Kelly handlebars were made in Cleveland. The adjustable stem pivot has about 25 notches in it which allows for 25 different height and width positions without changing the pitch of the grips

The Sager saddle (made in Rochester, NY) looks like it could have been made in 1997, not 1897. By the way, Sager made seats that were pneumatically adjustable for plushness in the 1890’s. Campagnolo attempted to revive that idea with their own version in about 1995. Some ideas just keep resurfacing…

The CAE features a New Departure coaster brake hub (that part is from Connecticut) and some really narrow pedals that squeeze the sides of a size 9 foot. The bike features a set of eccentric rear dropouts to help easily adjust the chain tension. It has a really good bell (that still works), and a neat collet system to adjust and lock the seat post height

For example, if you have a non-delivery contract involving Brazil real (BRL), then you most likely get the official BRL PTAX (BRL09) reported by the Banco Central do Brasil on SISBACEN Data System under transaction code PTAX-800 ("Consultas de Câmbio" or Exchange Rate Inquiry), Option 5 ("Cotacões para Contabilidade" or Rates for Accounting Purposes) and published around 1:15 p.m., São Paulo time. It is an average of several observations during the day. Likewise, if you have a non-delivery contract involving Argentina peso, you get ARS MAE (AR05) - the rate published by the Mercado Electronic Abierto on its website at approximately 3 p.m., Buenos Aires time, which represents the volume weighted average of all trades in the electronic market for this day in Argentina. Etc

But if you're looking for intraday, or time other than their close, or forward rather than spot rates, then there are just "unofficial" data vendors. The most popular spot and forward rates seems to be WM/Refinitiv published by State Street subsidiary WM and Refinitiv (former Reuters). Of the many FX platforms, CME's Electronic Broking Services (EBS) is probably the best known

The FX market is incredibly fragmented. There are no 'official' or correct FX rates, rather there is data that is compiled and distributed by reputable sources, such as central banks, or electronic dealer platforms, or even large trading house own pricing data

Here's an example of how exactly FX reference rates are being calculated for the exchange-traded USDRUB pair (USDRUB MCDF Curncy in Bloomberg, USDFIXME=RTS in Refinitiv). In this particular case, it's a 5-minute average of 300 per-second calculated "fixes" each determined as a weighted sum of VWAP and weighted mid-price. The multiple layers of averaging and weighting are not surprising given how much is tied to and settled based on these rates. At the same time, the calculated rates can be verified by anyone with access to Level 2 and last trade feed
