Top reviews:

Can be used with Shimano 10-speed road bike shifters by dkyrtata, 19 February 2015, 20 out of 20 people found this review helpful This derailleur came with my 10-speed road bike after I asked the shop to install one that would accommodate a 32-tooth cassette. I was a bit surprised that they used a 9-speed derailleur with a 10-speed shifter, but as long as it worked, I was not at all concerned. Recently, I came across this link which confirms that the shop was right. (scroll to middle of page): http://velonews.competitor.com/2014/02/bikes-and-tech/technical-faq/technical-faq-mixing-and-matching-10-and-11-speed-shimano-and-campagnolo-drivetrains_315933 In short this is what the link says: It is correct that a Shimano 10-speed MTB rear derailleur will not work with a Shimano 10-speed road shifter. . . . However, you can use a 10-speed cassette and 9-speed Shimano MTB rear derailleur with a10-speed 105 shifter (and a 10-speed chain). ‰Û¥ Lennard So for those of you who are using 10-speed road bike and want to use a larger than a 28T cassette, this is the derailleur to use. It has worked for me for 4 seasons with over 23,500km on it. Pros: comparable quality with 105-5700 derailleur and about 10 grams lighter (243g v.s 250g)

Super smooth by Beeflord, 15 October 2013, 6 out of 6 people found this review helpful I replaced a rather old LX rear mech with this one – bargain price at CRC. Once I had set it up properly (ie indexed the gears and readjusted after the cable had stretched) the shifting was fantastic. No noise, no fuss, just a super smooth shift up and down the sprockets – effortless and instant. I am using XTR cables with the PTFE coating which probably helps, but I think the improvement is at least 90% mech. This is probably the best upgrade I have made to my bike and worth every penny. If you are upgrading an older bike, as I was, then I couldn’t recommend this product more highly. Pros: very smooth shifting looks great Cons: none

      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.

      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.

      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.

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.


      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. Once you decide do not underestimate your gut feelings. Just believe in yourself and think about what you need and the salesman in the shop is there to guide based on your cycling requirements.
