General information about our shipping
I bought these wheels as I didn't want to spend fortunes on a wheel upgrade and while still a significant outlay, these are definitely in the affordable category for carbon wheels. The total weight for these wheels is on the higher end at 1900g, but you get 2 things for that slight penalty, the steel free hub, I cant stand it when the cassette cuts the soft alu free hub and the cassette gets harder and harder to get on and off, and the aluminium rim, which gives improved braking performance. These wheels are very well made and one of the things that attracted me is the shimano cup and cone hubs which reputedly go on for ever with a little maintenance and roll really well. I've done a few hundred miles on these wheels and while its not loads, its enough to get an idea. they are stiff, roll great, and look really good. Sure I would have liked the Dura Ace ones, but at almost half the price, these were the much more sensible option, and I'm certainly not disappointed. There was an issue with one of the plastic covers on the front hub, slightly rubbing and making some noise, sent the wheel back to Merlin and they replaced it under warranty with no issues at all. great service from Merlin as always.
Wheels arrived well packaged and true straight out of the box. Look very good on my cervelo. Ridden now a couple of times and have certainly made a difference to my average speed - almost 2mph quicker and certainly fast and stable over 20mph. Very highly recommended
First impressions: they look great! good attention to details, and cool graphics. I am replacing a set of Mavic Kysriums, so the weight is the same. On the road they feel stiff but not too harsh. Climbing and sprinting is awesome! These wheels don't dissapoint. In the last 2 weeks, i've set 5 new PR's on existing strava segments, which proves these wheels are fast. Can't beat the price for what you get.
Firstly, these wheels are heavy. Actual weight without skewers is 1980g. However, they look great and once you get them up to speed, they are very fast and stiff. Previously had 35mm profile wheels and I definitely notice the difference on a gusty day, sudden crosswinds can catch you off guard if you`re not careful. Best for TT or sprinters (although may be a bit heavy for some). If you`re more of a solo rider or climber, you may want to look elsewhere in my opinion. One of the wheels had a bent spoke but was swapped out the next day great service from Merlin.
Only a few kilometers rode with them, I rode alone and without any side wind. The wheels were true. We can see the advantage of the "aero" above 34-35 km/h.
Incredible wheels. Very durable great for larger riders. Perhaps the best value on the market today. These wheels do everything well.
Flex free, well built and constructed, outstanding value. Exudes quality. Great purchase.
A solid set of wheels that roll nicely. Good for racing and everyday riding.
Nice looking, solid, fast and... simply wow! I had the occasion to test drive my new set of wheels recently and I really appreciate the fact that they seems to always want more more more... More speed, more action, more road! The limit is now me, not the wheels! Pros: Built as tough as a tank, smooth rolling, silent. Cons: A little bit on the heavy side...
Solid & rigid wheel, no need to change the brake pads due to aluminium rim. A bit heavy (around 1900g) when climbing but can run fast in flat terrain.
Ordered these wheels late Saturday and they were delivered to Sweden by 10am Thursday. Great service by Merlin Cycles and super fast, tracked delivery (DPD). I regularly order parts from the UK as they are much cheaper than in Sweden and these wheels were no exception - cheapest online by far. Wheels are simply outstanding, they roll really well and make a very nice humm. I am no super fit roadie but I have always wanted a pair of aero wheels and the difference they have made to my riding is incredible with faster average speeds (by 3-4kph per 30km circuit) than with my old wheels (Easton EA30). The increased speed can only be down to the wheels as it happened overnight from fitting them and is certainly not down to a super-human increase in fitness! I am one very happy customer!
