Top reviews:

Crisp, easy to set-up shifting, but with weak spring tension. by MaverickDH, 8 November 2013, 18 out of 18 people found this review helpful Using these with a X4 trigger shifter results in accurate and repeatable 8 spd shifting due to its simplistic 1:1 actuation ratio. Along with SRAM’s direct route cable routing, the installation of this unit is a breeze. The adjustment screws have large heads and when used with a proper size screwdriver don’t feel as if they will strip anytime soon. This is completely the opposite of the comparable 7-8 spd Shimano Acera M360 unit, which has much smaller screws for the high and low stops. However, the same cannot be said about the bolts holding the jockey wheels to the cage, as they are much smaller than the ones used on the M360 and are prone to stripping. Also, for those considering upgrading with aftermarket 11T jockey wheels, the bolt holding the guide pulley is offset from the centerline. This will require re-adjustment of the b-adjust, which may annoy some. Moving onto my real complaint about this unit, the spring tension is considerably weaker than the Acera M360 RD and thus results in a lot of chainslap. For a brand new derailleur to have this much chainslap compared to a four month trail-ridden M360 is really something! I cannot imagine how bad it will get if it even manages to survive on my bike for more than a month. Not due to durability issues, no not that, but probably because I will bash it clean off with a hammer :/ To be fair, neither the M360 nor the X4 are really designed for anything other than ‰ÛÏrecreational‰Û use. For the average commuter both derailleurs will offer very similar shifting performance, with the X4 beating the M360 in this category due to the 1:1 actuation, better cable-routing, and cage design. The X4 also beats the M360 in terms of durability, as the main adjustment screws are stronger with exception of the jockey wheel bolts. As closing remarks, for commuters who do not need stiff springs and want to experience better shifting, the X4 is a great choice. However, for cyclists geared more toward trail-riding or those who want to venture into heavier riding disciplines, the M360 might be a better alternative within this price range simply due to the stiffer spring. Pros: better cable-routing (direct route) better adjustment screws (won’t strip like acera) Cons: weak sring tension –> lots of chainslap jockey wheel bolts prone to stripping

Nice budget derailleur by ArtistCyclist, 1 September 2017, 1 out of 1 people found this review helpful At this price point i found it superior to shimano counterparts as this derailleur is slightly lighter, the cable sits close to the frame and out of harms way and it can handle wide ratio cassettes without any problem.The construction quality is good and the whole unit looks quite like the more expensive models in the SRAM lineup. The shifting is crisp and precise when coupled with SRAM X4 shifter. IMPORTANT: that unit will ONLY work with a SRAM shifter

        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 SRAM X4 7-8 Speed Rear Mech 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.


        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.
