Our* new… Cotic Roadrat

by Tony Farrelly   June 21, 2010  

Loads of you have been telling us about your bike(s) in our Kinesis Tripster Schwag Grab, which has prompted me to extract the digit and tell you about the latest addition to the road.cc team, our new company bike, well frame, it's a Cotic Roadrat and we're going to be using it to test kit and generally have fun… well I am, everyone else in the road.cc office can just back off!**

Like the Kinesis Tripster the Roadrat, is a versatile bit of kit we tested it last year in its drop bar, disc braked, singlespeed guise. Gettingt it as a frameset turns the versatility knob up to 11. You can run drops or flat bars, mini V brakes, Cantis or discs, 26in or 700c wheels, it's got horizontal dropouts for running as a fixed or singlespeed with an adapter so you can stick a derailleur on it, the only thing you can't do, to my regret, is fit calliper brakes, then it would be perfect in its all-roundness.

So heres my first build, I'm running it with the new Shimano 105 drivetrain, 10spd at the back with a 50-34 compact chainset. Despite the hills around here i've usually gone the 53-39 route, I was running the previous incarnation of 105 on the Ridgeback with a standard 53-39 chainset. My ideal would probably still be a triple though summat like a 53-42-32 or possibly a 52-42-30, you can get them so further down the line I might give it a try.

Pedals were the new 105 black jobs, but as you can see from the pics I've already swapped them for some more practical round town Shimano M324s - flat on one side, clipless on the other and poss my favourite pedal.

Rest of the kit is stuff we had lying around the office (the pedals were lying around my house), well except the Shimano RS 20 wheels which match up nicely with the 105 componentry. Oh, yes, the levers are 105 too. Bars are Easton EA70s, I like 'em and I'm not normally a fan of anatomic bends, but the ones on the EA70s just seems to fit. I've gone for a short 90mm Oval stem, a Bontrager saddle, on top of the old alloy seatpost off my Ridgeback, and some Halo Twin Rail tyres.

Current all up weight is 10.6Kg, I reckon I can lop off a kilo easily without being silly – those Twin Rails fear nothing the road can throw at them, but even their biggest fans couldn't describe them as light.

Longer term, I'm thinking flat bars a longer stem and disc brakes… or maybe drops, discs and hub gears.

* But I'll be riding it, just so as we're all clear about that

**Not including Dave, he's the man with the spanners… and besides it's several sizes too small for him.

Aha... that'll be the one the missus was loitering around at Mountain Mayhem, trying to pluck up the courage to ask if she could have a sit! Wink

Is it a small/short?

yes, they are, and yes they do. Chucked it around the Mountain Mayhem sportive yesterday no problem at all and have been commuting on the bike for a couple of weeks already too. Stopping is not a problem - the pads on the back have worn quite quickly, which is a bit odd, cos I'm very much a front brake to slow down with the back just for stopping, usually go through two sets of front pads for every one at the back.

It really is a great frame, my only nagging doubt is whether I should have gone for the orange one rather than playing safe with black Thinking

tony, can you run 26"MTB wheels with V-brakes on the frame, or only 700c's.. (as all the pics ive seen only have disc brakes when running 26"). ta.

hold on, it's down in the bike shed drying out - I'll go and have a look. As you say discs will work fine with 26in wheels but need to see if you can move the brake bosses… I'll just finish my tea and biccy and I'll report back

sorry Fringe, as suspected the brake bosses are in the wrong place - plus a quick shufty on the Cotic site doesn't reveal any noises being made about that particular combo and I reckon they would if you could. It might be that you could lower the brake boss at the back it's a two bolt affair, but you'd still need to slap on an MTB fork - and if you don't have one you might as well get some discs.

On the other hand what about running it as a 29er with v-brakes?

Yes, I was very tempted by the orange too - probably easier to spot in the summer gloom too
