Renthal Kevlar Lock-On Grips – long term test

Renthal Kevlar Lock-On Grips Long Term Review

Renthal Kevlar Lock On GripThere’s not a lot to say about these that I haven’t said before, in the, er, long term review. However, you’ll notice that it was posted May 2015 after a year of use. It’s now Sept 2016 & although the diamond knurled pattern now looks smooth & they’ve slightly worn to my hand shape, after 2 years 4 months I have no intention of replacing them just yet. The photo shows a new set from the Renthal site but I’ll edit in a better one of their current state soon.

So although these aren’t the cheapest grips out there, at £24.99 they’re the best I’ve ever used. With plenty of grip & also being the most hard-wearing I’ve ever found, Renthal seem to have done the impossible with these. It’s all down to a clever idea of mixing Aramid (Kevlar) fibres into the rubber compound. So as they wear, which happens slowly because of the Kevlar, more fibres get exposed, so there’s a constant resistance to wear whilst remaining grippy.

Told you it’d be short. Buy them if you can live with the one colour choice! I like it, and I’ve noticed they also do a set for motorcycles…

Easton Carbon Bar, Hope Stem

Hope FR Stem Easton Havoc Carbon bar reviewEaston Havoc Carbon Riser Bar & Hope FR stem

Bar & stem reviews by nature are never going to be long & detailed. Although important they all do the same job, so you really just want to know weights, dimensions & whether they stay straight & in one piece!

Hope FR stem

Hope FR Stem Easton Havoc Carbon bar reviewHope stems are available in a good range of sizes & rises so you should be able to find something that gives you good position. I went for a Hope as it seemed the best combo of price, weight & reliability available at the time. I was looking at the Renthal but it wasn’t any lighter, cost more & doesn’t come in a choice of colours…

One thing to remember when changing your steering setup is that wider bars move your hands outwards (obviously!) which brings your body position forwards. So if you want to keep a similar riding position as before a shorter stem will do this for you. That’s good all round as shorter stems are better for good steering. If you want wider bars and to move your body position rearwards then go for an even shorter stem

I fitted the Hope stem same time as the bars just over a year ago – no complaints so far, seems super-tough. What could go wrong you ask? Well, I’ve had other lightweight stems twist on me in the past. Not catastrophically but having one grip lower than the other isn’t that great!

Weight is quoted at 133g but that may be for the 50mm version, I have the 70mm

Officially the FR version is the 50mm or 70mm, in 0deg or 25deg rise, but they are plenty light enough for XC as well

Downsides? Only the price but there are a lot of more expensive stems out there as well

Easton Havoc Carbon riser bar

Hope FR Stem Easton Havoc Carbon bar reviewThis is a wide one! When it was released it was the widest DH bar at 750mm. DH you ask? On an all mountain/XC bike? Well, yes. It’s light enough & my paranoia told me that a lighter carbon bar would obviously snap! Probably not true but I don’t fancy being impaled by carbon. Alloy would be fine obviously…

The width suits me, although it seems a bit close when going through narrow stuff. Not hit anything yet though. Other stats are:

  • 9° bend 5° upsweep
  • weight – 235g

This bar feels straighter to me than previous risers I’ve used. Initially I thought it was less than ideal but I’d bought it so best put up with it. But riding with it for a while, it became obvious that being a DH bar it suits the fast, more extreme stuff better & works well with a lower position on the bike, elbows out. Then it fits really well. I’ve not long returned from an off road c2c & it was comfortable with longer days riding. Being carbon the stiffness doesn’t get in the way of vibration absorption & that adds to the comfort. Along with the stem comments above, I used to find that alloy bars would bend slightly on the right (mostly from messing about doing 180’s…) Tough carbon bars can’t so hopefully these will never have to be replaced!

Both were fitted at the same time. There’s been plenty of miles ridden & the odd crash but no issues, as it should be
