I’ve been running a Cotic Road Rat for a few years now and it’s been used both on and off road a reasonable amount. Off road I have done the HONC and CX Sportive along with a few local explore your back yard type rides. Fitted with 32c CX tyres it’s pretty capable only limited by the fairly tall compact road gearing I run.
Certainly worth a look and robust enough for some off road touring with fairly good mud clearance on CX tyres, 29ers would be a bit much. Better than a Pompino/pompetamine though.
Discs are great. BB7’s in my case on 160mm discs.
Mines using Fleegle bars though I might actually get round at some point to fitting the Midge flared drop bars for the extra hand positions and a shorter stem to suit. However the way it’s set up is comfortable for hours.
Handling is good and with the horizontal track ends the wheelbase can be altered a bit. Takes a rack and guards.
The only downside really is the very robust build if you want something that feels fast and flighty, as it won’t.
Versatility however is it’s forte.
Open pro rims on XT hubs have coped very well with the mixed riding with 32c CX Houfalize off road, 28c Marathons (Winter/towpath commute) and 26c road tyres for summer tarmac commutes.
I probably wouldn’t get another as it’s a bit too close to the MTB’s I have and a bit far from the pure road bike in performance terms for what I need these days but have no complaints in terms of what it is capable of.
