Review | Syncros XR 1.0 SL: A lightweight, carbon railed racing saddle

by 0

Looking for a lightweight saddle to give you the edge in a race? Jason tried out this carbon railed offering from Syncros.

The Syncros XR 1.0 saddle sits at the top of the Syncros XR range of saddles and sports a carbon base, carbon rails and not a great deal of padding to keep the weight down. Other saddles in the range (the XR 1.5 and the XR 2.0) have titanium rails (a bit heavier) and cromo rails (heavier still). There are a couple of women-specific models as well in 1.5 and 2.0 flavours. All are available in narrow and wide versions, depending on the width of your sit bones. This one is the narrow version.

“Lightweight, carbon railed racing saddle” doesn’t shout “hours and hours of pain-free happiness”, does it? I rode this saddle for hours and hours to find out.

The SL in XR 1.0 SL presumably means “superlight” and my god, this thing is very light indeed. At just 167 grams on my kitchen scales (Syncros claims 170g but my scales are from Aldi so we’ll call it 168.5g) it’s about the same weight as 5 packets of crisps and about 60g less than an average 29er inner tube.

There isn’t a lot of padding, but padding alone isn’t the key to a comfortable saddle. It’s also got a super-stiff carbon base, which means that there isn’t any give. You’re probably expecting me to say that it feels like sitting on a lump of hardwood, aren’t you?

Why do you ask for registration to view some articles?

We get asked this a lot. The simple reason is that content is increasingly expensive to commission, create and publish and where once the cost of this process was mostly covered by advertising revenues, now that’s no longer the case. We increasingly rely on our paying members to keep Singletrack going and we’d love you to become one of our supporters. however, that’s not we are asking right now. You can read the rest of this feature simply by registering an account on our site.

How does being a free, registered user help you?

A good question and it’s a bit complicated. It’s NOT so we can sell your email details, or even to send you newsletters. Our last newsletter was sent out in early 2018 – we really should send out a few. It’s not so we can show you more ads either – in fact when you register we show you fewer ads. The reason is actually because registered users come back and look at more of our content. They start interacting with us and posting comments of their own and joining in forum discussion. That level of interaction is what eventually feeds our new subscriber numbers and so for us the journey to gaining new subscribers is to start by encouraging you to simply register an account. We hope that the benefits that will bring to you will be the first step in you joining us as a paying Singletrack Premier supporter.
