CERAMIC SPEED COATED BEARINGS
A couple of issues back we looked at three CeramicSpeed products that were fitted for testing. From a coated ceramic bottom bracket, to some fancy Titanium jockey wheels on coated ceramic bearings, to a full complement of coated ceramic bearings for DT Swiss 350 hubs.
CeramicSpeed back their products up with a 6 year warranty, but you still need to service the bearings. Here’s a look at how everything has been working over the past few months.
INITIAL IMPRESSIONS
The bottom bracket bearings and jockey wheels were smooth from the get go, running noticeably smoother than the stock units after fitting. Of course, without a lab testing for friction it’s hard to quantify. But with a clean drivetrain with a fresh, light lubrication, and the clutch on the Shimano XTR rear mech adjusted to be just tight enough, but not too tight, the drivetrain ran like a dream. In a workstand, spinning the cranks backwards the lack of resistance was very noticeable.
The hub bearings were a little problematic at first. They hadn’t been fitted correctly, being pushed in not completely square and with very minimal grease inside the bearings. This was rectified by a different workshop – and they were then spinning smoothly.
ON THE TRAIL
This collection of top spec CeramicSpeed bearings were put through their paces on the bike of an elite cross-country and marathon racer, to make sure they really got a good run. They were used in the dry dust of Tropical North Queensland, across the wet pine forests and fast farm roads of the Black Forest in Germany, on the gritty trails of Zermatt, the high alpine trails in St Moritz, and in the rain in Livigno. They were also used for course practice and racing at the the XCO World Championships and XCM World Championships.
“With the CeramicSpeed bearings installed I experienced a new level of effortlessness,” stated our tester. “Every pedal stroke gave a sense of silent, buttery smoothness, with my feet gliding around the pedal stroke. The feedback from the bike was incredible - it felt a lot faster.”
Where the biggest difference was noticed was in the wheels. They really changed how the bike maintained speed, even above the normal high-quality DT Swiss bearings.
“They took freewheeling to another level, as my bike would pick up speed and gain momentum like never before. It’s hard to put a number on it but I can definitely say for a racer there are noticeable advantages to having these bearings installed - especially if they continue to last this well.”
No item missed a beat during three months of use, when following the maintenance instructions.
IN THE WORKSHOP
The jockey wheels come with a small lubricant bottle, to be used after washing or really wet rides. The bearings in jockey wheels are tiny, and the seals cannot be the same as on hubs. This was probably done not as frequently as required, but after a full strip and re-grease there is no major change in the performance. Maybe, they’re not as smooth as before. But they are still far smoother than stock. The pulleys have no sign of wear, as you’d expect from Titanium.
The bottom bracket had the seals removed with fresh grease once, and then again with a full degrease and clean before this review. This still runs like a dream, and the grease was always clean. The cups are easy to press into the frame, and remove, which is a nice touch. You can also remove the insert to access the bearings easily, keeping the cups in the frame. This is very useful for maintenance.
The wheel bearings are in situ and after lifting the hub end caps, everything looks clean. They’ll get a look at later in summer, with a full clean and re-grease and fresh seals.
ARE THEY WORTH IT?
Bearing in mind the complete collection tested here is about $2000 these upgrades won’t suit many people. These units are the cream of the crop, the coated ceramic items, and the Titanium jockey wheels. With proper maintenance, these products will provide exceptional performance for at least 6 years – possibly more. Having used other after market ceramic jockey wheels, the pulleys have worn in 18 months, so a Titanium set selling for about double the price actually isn’t bad value. But regardless of years of use you may or may not get, it’s a huge outlay. The performance returns are there, but it is up to you whether the value is or not. If you are looking for the ultimate upgrades to an already sweet bike, you might have found the last pieces.
