Sigma, the first in cycling computers
Germans are known for many contributions of quality. From producing cars like the Mercedes Benz to scientific advancements like Roentgen and the discovery of X-rays, Germans are known for being precise thinkers and sticklers for quality. Sometimes they are meticulous to the point of being anal retentive, but that works out well for us when it comes to quality cycling equipment.
Sigma Sport, a German company located in Neustadt an der Weinstrasse, is a prime example of how meticulous focus on a project can, and will, produce a quality result. Sigma Sports began in 1981 with an idea. This idea would spawn another great addition to the vast world of bicycle accessories, cycling computers. Frequently Avocet is given credit for developing the first electronic cycle computer, but if you research the dates you will see something different. Avocet brought their computer to market in 1983, whereas Sigma Sport was on the scene in 1982. So it seems Sigma Sport was the first to market with the Cyclecoach, a cycle speedometer which was the predecessor of today's modern cycling computer.
Sigma's original cycle speedometer, the Cyclecoach, looked like some sort of lab equipment. Much like today's super Sigma cycling computer, the Cyclecoach told the speed that the rider was going, calculated the total distance and maximum speed, and if you had the optional chest strap or fingertip hood heart monitor, it would give you your pulse as well. The Cyclecoach was about as big as a circa 1980's calculator, and the finger hood pulse monitor was a pain to use, but it was a serious step above the conventional tachometers of that day and age. Cyclists were more assured of accurate data than with the tachometer.
By 1986, Sigma Sport developed a wristwatch version called the Pulsecoach to get that pesky finger thing under wraps. They also released the first Velostar cycling computer that offered speed, cadence, distance, averages, tripometer and pulse. The technology was beginning to advance and Sigma was at the head of the pack.
The late 80's, early 90's brought forth the BC series computers. There are actually many people out there who still use the original BC models because they were such durable and efficient cycling computers. If you don't smash them, they just keep going.
Consistently seek advantages arising from changes in markets, science and society, Sigma saw the need to advance past the computer division and seek out new product lines to create. In 1997, Sigma expanded their product line to include lighting accessories. The Ellipsoid and the Diode were the first lighting products for Sigma. The Ellipsoid was a conventional halogen light that threw out a bright beam for night rides; it attached to your handlebars and is still in use today. The Diode is a tail light that attached to your seat post. These two lighting products set the stage for the Pava, the Hiro, the Smilus, the Paxi, the Siled Xtreme and the Quadro X of today.
Throughout the years, Sigma has continued to advance in the field of cycling accessories. From cycling computers to heart monitors, head lights to tail lights, they take natural pride combined with German ingenuity to bring us cyclists the best of the best no matter what our needs are. Whether you're a professional racer, an everyday commuter or simply a recreational rider, Sigma Sport's entire selection of products is designed to suit a wide range of athletes. Their goal is the same as it was in 1981: to offer customers the highest quality product at affordable prices.

Review of Zinn and the Art of Mountain Bike Maintenance
Product Description
In 'Zinn and the Art of Mountain Bike Maintenance', Lennard Zinn explains and demonstrates how to completely and properly maintain every component of a mountain bike, including chains, derailleurs, shifters, wheels, brakes, cranks, bottom brackets, pedals, saddles, seatposts, suspension systems, handlebars, stems, headsets, forks, and frames. He describes and rates every repair and counsels the novice bike mechanic how to decide whether or not to take the bike to a bike shop for professional attention. Extensive line drawings show how parts fit together and illustrate the tools required for every type of bike. Completely revised and updated to include the most recent information on state-of-the-art mountain bike components, emergency on-trail repair tricks are also explained.
Review
Whether you have a shiny new mountain bike or one that has been on more than a few trail rides, this book is a must to have in your collection. Mountain biking is a little different than most sports, you're usually out in the wilderness, miles away from the nearest phone or road, and putting yourself (and your bike) through a pretty gruelling workout. In Zinn and the Art of Mountain Bike Maintenance, Lennard Zinn does a great job of making sure that if the bike part of the equation fails, you'll know what to do. From suggesting what tools you should carry with you, teaching you how to use them, and giving you a quick lesson on how each work, this book covers it all. The book uses illustrations instead of photos, so it's easy to tell what's going on, and it covers all the different types (and eras) of components that you'll find. Coverage ranges from the basic (changing a flat tire) to the complex (changing your fork or bottom bracket) but is clear throughout. I highly recommend this to anyone who's doing serious riding and wants to learn more about how to tune and fix their bike. As your bike grows older and you take longer rides, things WILL break or wear out, and knowing what to do in those cases is well worth the price of the book. Verdict Hands down the best bike repair book out there. Make sure you get the latest version so you'll be up to date on the latest componentry.

Does a Road and MTB seatpost really differ?
I am thinking about buying one, but they are being offered as Road cycling seapost.
Yes there really can be a difference in the posts. Many times the frame of a mountain bike will be smaller in general than a road bike. Disregarding the possible difference in diameter of the seat post, many times the seat post length on a road bike will be too short.
If your seat post is too short and you hit a bump, the post could break and end up going through you. You don't want that to happen.
Seat posts are marked with a maximum extension length (that is if someone didn't already cut the post down destroying this mark).
If you have the post up higher than this mark it can fail. This isn't just a possible pain in the a**, it could be fatal.
Consider using the correct post for the correct bike. It could save your life.
Fuji Nevada 4.0 review
Fuji doesn’t have a particularly high profile in the UK MTB market (although there are plenty of Fuji Track fixed-gear bikes out there), but it’s got a decent range of hardtails on offer, of which the Nevada 4.0 is the cheapest. Ride & handling: Balanced, confidence-inspiring ride The Nevada benefits hugely from being one of the lightest entry-level hardtail bikes around – it’s the best part of a ...
