The guy in my LBS was very helpful and assured me that it would suit my purpose
and also manage my weight (265).
I was concerned by the lack of any suspension but I have just completed my first ride of approx
5 miles over loose gravel, tarmac, dry mud etc and had no probs at all. It was a pleasure to ride
and fits perfect.
Next investment is a cycle computer to keep accurate check on mileage / speeds etc.
Any reccomendations?? Do I need to spend alot or will a budget model do?? Wired or Wireless??
There isn't a lot of difference between a cheap bike computer, and an expensive one, except that expensive ones tend to provide more information. The key with any computer, whether it be cheapest or the most expensive, is the data. The key piece of data is the circumference of your wheel in millimetres. The best way to get this information is to measure it. Measure off a distance, then ride that distance and see how many times your wheel goes around, this should get you within 1mm of accuracy. One of the problems is that the computer counts the number of times the magnet forces a reed switch to close, this is once per wheel revolution, by multiplying that with the known distance it gives you the distance travelled, distance over time gives speed.
Most computers actually work in millimetres, converting that into miles and miles per hour for display purposes, In Metric countries it's easier to compute, simply move the decimal place 6 points to the left. A 40bit register can store up to 1 099 511 627 776mm which would allow an odometer to cover 999,999km or 620,000 miles, unlikely many riders could further then that without needing a new computer battery which resets everything.
Wired versus wireless,
Wired: Pros, fewer batteries to replace, no big ugly box on the fork, no RFI effect.
Wireless: Pros: No wire to try and work around.
I run a wired computer, the wire goes along the fork, at the top of the fork is a looser section, then it's attached to the front brake cable, and follows that up to the bars, where a small loop of excess wire is tightly wound, it then scoots over to the back of the computer. At several points a zip tie holds the wire to the cable housing, making it nice and neat.
