Top reviews:

Words cannot describe the sleekness and crisp shifting this groupo gives. by Joeyyy123, 27 June 2014, 19 out of 21 people found this review helpful Having decided to purchase my first serious road bike I rode countless bikes with various grupos. Veloce, 105, tiagra, rival and then this. And this swift, self correcting group set just makes cycling a joy and is virtually uncomparable, you can shift when you want without a hitch. The front derailleur is breath taking, the whirr of the motor instantaneously causes the shift. Over 500 miles into this group and hasn’t once slipped or not shifted. Some cycling “enthusiasts” argue that you lose the mechanical feel of man and machine. But to those people stuck in the past if you can afford the move to di2 do it. You will not regret it. Pros: little press required for shifting everything else Cons: rear derailleur abut ugly

Great kit, however, it will be damaged when you receive it by stuart80, 18 April 2017, 15 out of 17 people found this review helpful I’ve bought a lot from CRC but never left a review however my experience with this item has motivated me to leave a review. Firstly, the Di2 groupset is fantastic. It is overpriced for what it is though. The levers especially are a bit of a let down when compared with the non Di2 version. Yes, they are smaller, but the addition of two stitches and a big price increase means no carbon lever blade. Otherwise, it looks great and works really well. However, because this is Original Equipment, nothing comes in retail packaging. This would be fine if CRC simply put some bubble wrap around the larger sharp items such as the crankset, chain and cassette. However, everything will be rattling around in poly bags in a large box. One of the shifters I received had a mark down to the metal on the lever blade and the rear derailleur was scratched. Not good on something which costs å£1000 once you get all the bits you need to install it. The most ridiculous thing is, according to CRCs own customer support is that they say ‘because it is an OE groupset we can’t guarantee it won’t be damaged when you receive it’. And, you have to send the whole thing back if you aren’t happy with the state one item arrives in. So in short, great kit, but it will be marked when you get it, you’ll have to send the whole thing back with no guarantee the next one won’t suffer the same fate. So spend your å£900, just be prepared for it to not be cosmetically perfect and a lot of messing around if you decide any of the items aren’t in good enough condition. Pros: di2 works fantastically Cons: packaging is beyond poor will be damaged on arrival

Your selection entirely depends on how long, how hard and the location where you are going to ride.

Spare some time

Before you start hunting for a new bike, make sure you spend some doing research to avoid problems in future. You need plan right and buy right so do not rush into hasty decisions.

Budget a little more

Before you start shopping for your bike, consider the amount of money you can invest to accomplish your cycling goals. Then irrespective of the budget you have planned for, spare around two thirds of your budget to your bike. The remaining budget is for the accessories. Despite of the price range, you would need basic accessories like a pump, a helmet, bottle cages and a water bottle.

Gather information

The internet is flooded with information on different types of bikes along with detailed information regarding its parts and how they function. Do spend some time gaining knowledge about bike parts so that you understand the difference between different models, brands and frame materials etc.

This will help you buy your bike confidently.

Seek advice

If you know someone with good knowledge about cycling, or someone who had just purchased the bike, do not hesitate to seek advice as they can answer your questions and they will be happy to share their knowledge and experience with you.

Check with the experts

A second opinion is always better and for this you can simply visit the local bike shop near you and you can get advice on the type of bike you can buy and the different models you can choose from that suit your needs.

Consider the fit first

Irrespective of whether you buy a top brand model or just an entry level bike, it can be a disaster if it doesn’t fit. You can consult the salesperson and he can help you buy the right size. Then work out 4 different adjustments like handlebar height, saddle position, seat height and the reach. It is always better to hunt for shop with trained staff as they will take perfect measurements, help you settle on multiple bikes and accordingly swap different parts to adjust your position. This service will certainly cost you a little more, so you need to plan your budget accordingly. Do not fall in prey to some retailers who often offer bikes in odd sizes at a discounted price.

Experiment with a lot of models

Bike shopping is certainly not like buying a house/car that you purchase after looking at the first model you come across. Yes, when you are riding an old bike since many years now, then a new bike is certainly going to make a difference for you. This is because now there is advancement in technology. It is better to try out different models before you get the right one.

Narrow down your bike search

Looking at a plenty of models can confuse you in the sense you may end up getting frustrated with your search. It is better to narrow your search to 3 models like Shimano Ultegra 6870 Di2 Groupset along with your budget and the purpose of use. Once you narrow down your search, do not forget to take a test ride for 15-20 minutes or longer if possible. Before you take a test ride, make sure you check for fit adjustments and a tutorial briefing in about how the various operations of the bike.

You can simply reject even a perfect model, if you have to struggle stretching to get to the handlebar or you feel clumsy with the shifter that you may not have operated before.

Test the bike wearing the clothing you are going to use while cycling

It is always better to take test rides/bike fittings by putting on the same shoes, apparel which you normally prefer for rides. There can be difference in fit when you are wearing a pair of jeans than when you are in cycling shorts.

features

Take some time to think about your actual bike requirements and make sure you don’t fall in prey to something fancy or new that is being offered. Think if you need a bike that comes with disc brakes? Are you in need of electronic groupset? Is the bike equipped with rack mounts that you actually need? The answer to these questions can help you pay for what you need and ignore the things that you don’t.

Where to buy the bike from

The internet can help you buy stuff like game consoles, books etc., but for bikes it is always better to buy from a shop. A bike is something that you need to check for fits and other adjustments, accessories etc. It is something that you cannot order online without checking the bike. Make sure you buy from the shop that offers fitting service and help you in other bike adjustments.

Of course you will find the bikes quite cheaper when ordered online, but as a beginner it is always better to visit shop that sell different brands of cycles and provide first service free.

Look for personal service

There is no harm going for online shopping to gain the benefits of online discounts. But, ensure that you check for all the advantages that you actually need. Apart from fit sessions plus test rides, a shop will always make sure that you get proper assembling and they may also offer the one-time adjustment for free. It may include discounts on various accessories with your bike purchase.

Believe in your gut feelings

Although it is advisable that you take advice from experts and your friends, but after you consult the experts or friends, the final decision is up to you.

Now, when you take the final decision, simply click to read more reviews and get your bike. You will surely enjoy riding the bike as you had done a lot of research, planned your budget, consulted the experts and your final decision is based on a lot of factors that you considered. Now, it is the time to enjoy your ride and take good care of your bike. You can achieve your cycling goals as you have the right model in your hands to get going.
