Dawes Giro 300 Review

Welcome to Bicycling for Beginners

Dawes Bicycles have a good name in the UK for building high quality road bikes, mountain bikes and touring bikes. In recent years they have also introduced hybrids and heritage bikes. In fact Dawes make all sorts of bicycles including children’s bikes and BMX. They even make most of their most popular bicycles in male and female versions.

The first problem I encountered with Dawes was getting a brochure of their products. To do this you need to complete a form on their website and wait for it to arrive in the post. This took quite a long time and I thought that I had made mistake and completed the form again. Sure enough a few days later the brochure arrived, followed a few days later by another one!

The brochure contains glossy images of most of Dawes product range. This particular brochure (2008) is actually a large fold-out sheet of paper. There is very little information about each bicycle in the brochure and consequently little to learn from the product brochure that is not available on the internet already.

The second problem that I encountered in getting a Dawes Giro 300 was finding one! The days when bicycles were diligently hand crafted by skilled bicycle mechanics in their country of origin are long gone. I’m not sure if any bicycles are still manufactured in the United Kingdom. Perhaps one or two very small specialized bicycle manufacturers still persist. This is a great shame but sadly, the majority of our bicycles are now shipped by container from foreign shores. An example of this is that my Dawes Giro 300 was built in Cambodia (according to the packaging).

This type of manufacturing means that products are imported in batches. This means that products can go out of stock for large periods of time. This is what happened with the Dawes Giro bicycles at the end of summer 2008. This was frustrating but understandable, made worse by internet retailer claiming to have stock when they clearly did not have any. I recommend ringing and checking before placing an order with internet retailers. In the end I rang Dawes directly and they were very helpful indeed, or perhaps it just seemed that way because by chance it was the day that they had just come into stock. My local bike shop had already informed me that the bicycle were back in stock.

It was December when I actually got my hands on my Dawes Giro 300 for the first time. In the end I bought it through an internet retailer who was able to supply the cycle much cheaper than my local bike shop. I would usually have preferred to use my local bike shop but I live in a remote area and they do not offer a delivery service. It would have been beneficial to have had the bicycle set-up by the bike shop in advance.

My first impression of the Dawes Giro 300 is that it looks fantastic. It has a very elegant red paint finish. I examined it very closely and found no defects, scratches or blemishes in the finish. I only had to make a couple of slight adjustments to the bicycles original setup and it was ready to ride. If you buy the bicycle on the internet you have to complete the assembly at home. This is a simple task of putting on the front wheel, seat post and saddle and handlebars. The gears and brakes on my bicycle needed some very slight adjustments.

My first ride on the Dawes Giro 300 was just a quick “test ride” down the street where I live. I travelled approximately 1 mile and found that the front derailuer was not working properly. So I returned home and made some adjustment to it which involved altering the angle slightly and re-setting the tension on the cable. After these small tinkering sessions I test rode the bicycle again and it was excellent. It is just a fantastic “entry level” road bike in my opinion. It may not have the bells and whistles (actually you do get a bell – I didn’t bother fitting it though) that higher end road bikes have but it ranks above most other basic racers on the market. This is why I went to such lengths to acquire this particular bicycle. It is absolutely perfect for the casual cyclist that wants to cruise around on a fairly decent bike without spending a fortune.

There are a few negative aspects of this bicycle that I have discovered in the short time that I have owned it. One of the problems is the cheap and cheerful black plastic pedals that come with the bicycle. They look like they would be better suited to a child’s bike or supermarket MTB. I was very surprised that it shipped with these inadequate components and will upgrade them as soon as possible. Dawes has written their name on every conceivable component that they can fit their name on. In addition almost every component and the frame have Dawes logo plastered all over it. I’m not bothered about this because it looks really smart. I just feel slightly annoyed that the one place where a really good Dawes logo should be is on the front of the frame (headset). In the old days bicycles had metal logo badges that were fixed on with rivets. Dawes have slapped on a foam sticker that is already beginning to peel off. Some of these very cheap money saving exploits spoil the overall image of a very good bicycle.

The fact is that the Dawes Giro 300 is a very good racing bicycle. It is fast and furious and that is all that matters when you are infected with the road cycling bug. Please read my next post about Cycle Clothing

Bicycle Maintenance

Welcome to Bicycling for Beginners

There is little doubt that bicycling is great fun and good exercise and generally an enjoyable activity. However it has to be remembered that cycling does have a dangerous side. If you maintain your bicycle properly you can greatly reduce the risks involved. Keeping your bicycle in good mechanical condition is your own responsibility. Failure to maintain your bicycle could lead to a dangerous accident and/or expensive damage to your bicycle. It is never nice to set out cycling and end up having a long walk home instead!

New bicycles usually arrive with an instruction manual that tells you how to look after your specific make and model of bicycle. This is useful information because it is specific to your components and type of bicycle. I’ve written a short guide to some very basic general bicycle maintenance. If you bought your bike second hand or ride one that you found in next doors shed/garage my maintenance guide might be helpful!

Bicycle Tyres
It is important to maintain your bicycle tyres by keeping them inflated at the correct tyre pressure. This will decrease wear to the tyre and reduce the chances of getting a puncture in the tyre. Maintaining the correct tyre pressures will also protect the wheel rim from being damaged if you hit a pot hole, road furniture, stone or other obstacle. The tyre pressure information is usually written on the tyre wall. Regularly check your tyres for levels of wear and damage. Examine tread carefully for any cuts in the tyre surface and remove any sharp objects that may have become lodged in the tyre.

Bicycle Brakes
There are four main types of brakes used on bicycles.
  • Calliper Brake
  • Cantilever Brake
  • V Brake
  • Disc Brakes
There are two types of disc brake.
  • Mechanical
  • Hydraulic
Mechanical disc brakes use conventional cables and brake levers when operated. This type of brake requires manual adjustment to offset any wear of the brake pads. Check the condition of the brake pads and cables regularly.

Hydraulic disc brakes use dedicated brake levers and brake fluid when operated. Some types of hydraulic disc brake adjust automatically as the brake pads wear down whilst others require manual adjustment. There are two types of brake fluid to use in hydraulic brake systems.
  • Mineral
  • Standard
Regularly check the brake pads for wear and alignment. Brake pads should be evenly spaced from the wheel rim and ideally 1.5mm from the rim. The pads have an indicator that show when they are ready to be replaced. If the pad is worn to the indicator line it needs to be replaced. Failure to replace the brake pads could result in either an accident or damage to the wheel rim or tyre. Lubricate brake pull-cables. If the cables are stretched, frayed or make a creaking sounds when the brakes are applied they need to be replaced.

Brake blocks (or pads) have a series of grooves in them to indicate when they are sufficiently worn and require replacement. When the blocks are worn down to the indication markings it is time to replace them with new ones. To make minor adjustments to the braking pressure there is usually an adjustment screw where the cable enters the brake lever. If you discover that there is too much travel on the brake lever make an adjustment to the cable so that the brake blocks/pads are closer to the wheel rim (approx 2mm).

Bicycle Chain, Derailleur Gears and Cassettes
There are lots of different types of gears and gear mechanism fitted to bicycles. The most popular type is the front and rear derailleur system. This is popular with road (Racing), mountain (MTB) and touring bicycles. This type of gear mechanism is also used for most fitness or hybrid bicycles.

The highest gear is selected when the largest chain-wheel (front) is coupled with the smallest sprocket (rear). The lowest gear is selected when the smallest chain-wheel is coupled with the largest sprocket. The gear mechanisms work by adding tension with the gear levers. When tension is added the mechanism moves the chain over to the next chainwheel or sprocket. To change down gears tension is released and the mechanism retracts. The front mechanism operates the chainwheel and the rear mechanism operates the rear sprockets (collectively known as a gear cassette).

To ensure that the front and rear gear mechanisms work correctly make sure that they are free from dirt, grit and (particularly) sand. Oil all the moving components of the front and rear derailleur with an appropriate lubricant (usually a dry molybdenum oil).

General Maintenance Tips
  • A common mistake in bicycle maintenance is the use of deep penetrating oils on chains and bearings. Never use DW40 or similar products on your bicycle chain (or bearings). This type of product is too thin to cope with the friction of a fast moving chain drive. In addition this type of oil will actually remove existing lubrication on the chain and could cause lasting wear and damage to the bicycle chain and sprockets. Never spray this type of oil into bearing housing either for the same reason. This will dissolve the grease in the bearings and can cause a large amount of expensive and dangerous damage to your bicycle.
  • Avoid cleaning your bicycle with a pressure washer because it is possible to strip lubricating grease from the bearings. If you do decide to use a pressure washer take care not to direct the water jet in to any bearing housings on the bicycle.
  • Keep all gear and brake cables lubricated with a suitable PTFE lubricant.
  • Routinely check your tyre pressures and inspect the tyres for any cuts or embedded sharp objects.
  • Check that the headset allows the bicycle to steer smoothly. There should be no stiffness or juddering in the bearings.
  • Check for loose or damaged wheel spokes and examine the wheel alignment.
Bicycle maintenance is mostly common sense. Keep all moving parts (except gear levers – which work under tension) adequately lubricated with the correct type of oil or grease for your bicycle components. Keep the bike clean and make repairs when necessary. Look after you bicycle and it will look after you.
