As you know, I like quirky things; the quirkier, the better in fact!

But, quirky isn’t always enough; stuff needs to work well too. I mean, look at Boris Johnson’s hair; it’s quirky as you like but what use is it, really?

Allow me to introduce you to the Surly Tuggnut.

Of course, it’s made by Surly so you know it’s going to be really well engineered, rock solid and will no doubt satisfy even your quirkiest of desires.

Designed primarily for single speed / fixed gear bikes, the whole point of the Tuggnut is to incrementally move the rear wheel back in horizontal ‘dropouts’ to achieve the all important correct chain tension without the need for an ugly derailleur or external chain device or some kind. With 2 separate axle mounting points and uber fine adjustment available from the little thumbscrew, finding the right position for your rear wheel is a snap. And, thanks to a neat little washer type attachment, you can also run quick release wheels just as easily as solid axles.

But wait, the Troll isn’t a single speed! Look, there’s a big old shiny cassette and a rather nice Shimano Deore Shadow rear derailleur there – what on earth do you need a Tuggnut for on a geared bike?

Well, the answer is simple. Because I’m running 2.2″ wide Halo Twin Rail tyres and a triple mountain bike chainset, whenever I’m climbing some horrendous hill in the little chainring and the biggest cog on the cassette, the trailing edge of my front derailleur *just* rubs on the outer edge of the rear tyre. It’s only about a half a millimeter, but it’s more than enough to need fixing. The only real solutions available were:

  1. Replace the bottom bracket for one with a longer axle – Not gonna happen, far too much trouble and far too expensive
  2. Replace the tyres for something skinnier – Not gonna happen, far too attached to my Halos and far too manly to run skinny tyres on the Troll
  3. Buy a Surly Tuggnut – Sold!

Available around the £25 range, the Tuggnut is hardly the most expensive bit of kit out there and the best news is, you only need one for the drive side of your bike! You can see here how much I managed to move the rear wheel back; not much, but just enough to avoid any more interference issues. You can also see in this shot the beauty of those sliding disc brake mounts; nothing more complicated here than loosening the bolts, sliding the caliper back a little and retightening the bolts.

So yes, the Surly Tuggnut works extremely well. And the quirk factor? Well, that’s brought to you by the fact it also doubles as a bottle opener! Yep, at the end of a long, hard day’s trolling about, you can even crack open a cold one at the side of the trail. Sweet.

While we’re on the subject of quirky, yet functional accessories for your Surly (and I believe there are other bike manufacturers out there), you could certainly do a lot worse than get yourself one of these.

Maybe I could get Karen to knit me an orange one…
