Mr ParkinsonI have only had the wheels a couple of weeks and as expected after such a short period I have experienced no problems. Roll well and true. Replaced a pair of Ultegra wheels upon which the rim wear indicator disappeared disappointingly quickly on the rear wheel, put these RS21s on and if I am honest, on one of my longer lumpy rides, I noticed very little difference to the Ultegras whilst ascending Holme Moss and various climbs around that area. As ever great service from Merlin.
GregBought these wheels to upgrade no-name wheels that came with my cheap road bike and the difference is night and day. Wheels came perfectly true out of the box, cassette installation was easy, and the ride on the bike is much smoother. Spoke pattern is pretty nice and after putting a few hundred miles on them, they seem to be holding up very well. Freehub may be a little on the noisy side (haven't had much experience with different wheels), but doesn't bother me in the slightest and pedestrians still don't hear me come up behind them anyway... Would buy again for sure.
SeanVery happy with my purchase. I have used this wheelset before so had no doubts about ordering them again. For the price, they provide everything I need: they are light and rigid and despite some heavy riding by me at times, seem impossible to buckle! I must also praise Merlin for the delivery - ordered on Tuesday, delivered on Thursday in Germany to the exact hour that was communicated by email (and cheaper than local suppliers). Very happy!
WillemToppertjeNice build quality, relatively light and good looking. True and straight, fairly stiff.
HawkinsGreat budget wheelset. Rims are true, good spoke tension, reasonably stiff ride... can't ask much more for a product at this price point.
Greg HBought these to replace my ageing and damaged R500s. I put them on the bike and Wow, what a difference. Lighter and accelerate quicker and my average training ride is 1mph faster for the same work and Strava suffer score.... Thinking about a second set at this price for my spring/autumn trainer.
Jamie rides a CubeChanged out my 3 year old, well maintained, Fulcrum racing 7s for these and felt an immediate improvement, done around 120 miles so far with no complaints, service from Merlin the usual second to none, ordered after mid-day, arrived before mid-day the following day on a standard (free) delivery.
C SavaNice sturdy wheels. They're replacing the aging RS-10 which lasted more than 12k kilometers until one spoke eventually snapped. Equipped with a Shimano Ultegra 6700, they will give you a ride like a Cadillac
Mr HyderTop notch wheels, first 300 miles on fairly brutal British roads, still perfectly true. Look great too.
CumbrianDynamoGood solidly made wheels, with nice bladed spokes. Have been using them for a couple of weeks now and am happy with the performance.
Mr GThese wheels are great. Excellent power delivery and great handling in corners.
Mr DessentRoll well, fairly light. Nice improvement over previous shimano R500s
Mr NylanderI upgraded 9 speed to 11 speed and realized that I also have to buy a new rear wheel. After browsing around, and reading the great reviews on Merlin, I decided to buy Shimano RS21. I have not regretted it, especially after running down in some big potholes! The wheels are still intact and I can really recommend them. Especially quality in relation to price!
Gordon ShawGreat wheels at a great price. When you consider that Cannondale put the RS11's on their Synapse which is winning bike of the year awards left right and centre, and these wheels are a step up, you know you're getting quality.
Mr WrightPretty much the same as the old RS20 that I use as general. purpose/winter wheels. The RS21 has subtler graphics and will accept 11 speed cassettes (as well as 10 speed if you use the spacer provided). Best wheels in this price range in my opinion. The hub bearings have excellent seals and if cleaned, greased & adjusted once a year will last forever. The wheels are fairly light and riigid - regular use over loads of cattle grids testifies they are robust.
Mr PaganottoGreat budget wheels at an amazing price.They are typically well made as you would expect from Shimano using their tried and tested cup & cone bearings for amazing durability. The bladed spokes are great too making a lovely whistle at speed! They aren't particularly light at approximately 1800g but they are very sturdy so the extra grams don't bother me. If you are after some wheels to speed up your ride look elsewhere but if you want some smooth rolling, stiff, durable wheels at the cheapest price on the web give Merlin a shout!
Mr EdwardsNo problems as yet, staying true, good wheel for winter riding
YoshiI have been using a sub 1500g lightweight during the season and bought these for winter training/commuting, and I have ridden a few hundred miles over pothole ridden roads and they seem to be built like a tank. Still true like a boss. For the price the weight is reasonable. The hubs are smooth and the rear free hub is quiet (not silent). The understated aesthetics are also refreshing. It gives a smooth supple ride, which I like, as more rigid sets can deliver a fair beating to your nether regions. You will have a hard time finding a better quality wheel set for the price, especially at Merlin prices, and I think I will be using these for everything but racing.
John TrailriderGreat wheels for the price, usual Shimano quality, a real step up from the lower priced wheels. Straight pull spokes, low spoke count, fairly stiff. Super smooth bearings, ultra quiet freewheel. Very understated graphics. Highly recommended and a bit of a bargain at the moment.
Mr O SullivanNice wheels, great value. Very smooth rolling. Best bit is the blade spokes, nice sound at speed.
Mr PymWheels feel light and fast, obviously inheriting some genes from the Dura Ace wheels (I have C24's). Using with a 105 10 speed groupset, and all seems fine.
Mr KeeleyI put a lot of research in to buying these wheels. Stu Bowers from Cyclist magazine settled it for me when they were standard on a Senza Giulia Custom and he rated them highly. For the money, especially Merlin prices, you will struggle to find a better wheelset. Pick up much better than my stock wheels, and if like me you want them "decals off", they look all kinds of awesome.
Mr McCuskerHaving ridden them a few hundred miles I can say their far superior to my stock wheels. Their considerably lighter, roll better and are stiffer than my previous wheels which I thought had a disconcerting amount of flex in them. The ride feels a lot different (better) their obviously a lot more energy efficient. With these on I can ride a lot quicker on the flats and on the hills. They also look nice. My previous wheels were 32 spoke rigida flyer rims on formula hubs.
Dave TGreat set of wheels for the price. Light and fast. Set is 400g lighter than the RS10s they replaced. Spokes are way more aero too. Usual excellent service and best price from Merlin.
Mr garthwaiteA great pair of wheels from Shimano as I find all their wheel products. They are great value for money and with the metal freehub less prone to wear which I have experienced with none metal freehubs from other manufacturers. They are a great training or racing wheel remaining true after some inadvertant pothole abuse.
