General information about our shipping
Finally got to use these last weekend, covering 100 miles of very hilly stuff. I'd kept my old Bontrager XXLs on through winter with 23mm tyres and Crud mudguards. The switch over was easy, 10 speed block used with provided spacer (not used with 11 speed block), gears perfect, no adjustments needed. New brake blocks, calipers needed opening for new bigger 25mm Conti GP4000 IIs. The RS81 rims are also wider than the XXLs. The XXLs are light wheels so no weight difference but the RS81s roll really fast, so fast my mates commented on how they had to pedal to keep up on fast descents when I was freewheeling. The new 25mm GP4000 IIs are known to have very low rolling resistance which will have helped but there is no doubt the RS81s are very quick. As mentioned above we headed out to the steepest b**stard climbs around us training for a very hilly sportive and these wheels felt very responsive, strong and true when pumping out the saddle going up and very steady when flying down the other side and round hairpins. It's also very nice to know you've got perfect new braking surfaces, the old XXLs were getting properly dished through wear. I used my old QR skewers as they are titanium and lighter than the supplied Shimanos. I imagine over the next few hundred miles they'll get even quicker as they run in. Very pleased, money well spent on great quality wheels that look good too without being flashy. The carbon laminate has a lovely deep gloss about it.
They were true out of the box and ready to rid, and they were delivered to Turkey in 11 days, which is really fast as the package was checked for the customs fee. Merlin customer service was quick to answer my questions before and after the order. As for the wheels, they are light and stiff. I had a mavic kysrium equipe wheelset before this one. The Rs81 set is 250 grams lighter and a lot stiffer. With mavics I used to lose pace whenever I climbed standing and continued sitting. Therefore, it was almost always an effort in vain to gain pace. With rs81s I can increase my speed uphill and I am able to keep it when I am back on the saddle. They are accelerate fast and retain speed well. I have ridden about 800 km/500 miles without any problems. I have been attentive to the braking performance as I read some negative reviews on forums by some users having braking problems (pulsing brakes etc.) because of the braking surface, but I haven't noticed any irregularities with the braking. They have been reliable without any issues.
For an entry level training or beginners race Wheelset, these are not only great vaue, they're well built. Look after the hubs with quality grease and they'll go forever.
They are lighter than the stock wheelset on my Specialized Allez. Installed Ultegra 11sp and I've ridden maybe 40 miles on them and so far, no issues. Surprisingly, they feel lighter than the zipp 60 I was looking at. Overall, extremely happy with my purchase.
Love these wheels. Light weight and spin up to speed well. Are strong and take the bumps well.
Great wheels! The wheels are super smooth and light. These wheels gave me the confidence to tackle corners and climbs much faster than before. I highly recommend these wheels to anybody who is looking to upgrade. The wheels are super stiff but comfortable so I can put a lot of power down. Besides that, Merlincycles is awesome! I received my shipment within 3 days across the country. Best shopping experience by far.
Very nice wheelset for the money. Light weight yet feels strong. I like having the strength and lightness of carbon combined with the alloy braking surface. I replaced stock Bontrager wheels on my Trek Domane and they really brought my bike to life.
Good light wheels, similar to the dura-ace wheels, a fraction heavier but half the price. Fantastic value!
Great price anyway from Merlin, then an extra 10% is sweet. Great delivery. Wheels true out of the box. Looking forward to losing some weight over my Mavic Aksiums. Also other reviewers on other websites have said how the carbon makes for a more comfy ride, but the alloy braking surface means there's no loss in braking power, as with some carbon wheels. Very happy .
I bought these primarily as my new 'best' hoops and particularly for a hilly sportive. However, I'm now using them permanently. These are great wheels; they are light, solid, roll well and are relatively quick. They appear hardwearing as they survived a hard fall on their first day out. Given the recent rain, I have appreciated the improved braking that you wouldn't get with full carbon. I have only done a few hundred miles in them so far, so it is too soon to comment on their reliability.
