What is 29+? They are 3 inch wide (or thereabouts) tyres on wide - usually 45-50mm wide 700c/29"/622mm diameter rims. These tyres will not fit in most mountain bike frames, even those with lots of clearance, so I needed to design a frame around them.
Why 29+? It's pretty simple really, they give you a lot of the same feeling as a full fat bike but they roll significantly better and save a lot of weight. They also benefit from not needing unusual width cranks and hubs, so you can still use a regular pair of 29er wheels in there for race day or outrageous mud clearance.
The fine folks at Surly Bikes are the originators of the 29+ standard and for the past 18 months or so have been the sole mass producers of bikes made for this size wheel. Singular aims to launch the second production frameset for this wheel size with the Rooster.
The Rooster benefits from the experience of designing the much vaunted Swift 29er and the Puffin fat bike. Both those bikes are renowned for their intuitive and sharp handling, blended with the classic style of a simple and beautiful steel frame. The Rooster will share those same attributes in a 29+ package.
My goal with the Rooster is to create a frame which is specifically designed to perform optimally with 29+ wheels. When developing the Puffin Fatbike some people asked - will it fit 29+ wheels? The answer was no - and that was because I wanted to make that a bike which would perform best with full fat tyres, not compromise it so that we could shoehorn 29+ wheels in there. Similarly, the approach with the Rooster is to look at it from the ground up in order to create a bike which functions best with this specific wheel size.
Tubing is a bit beefier than a Swift, the traction and speed generated by the big tyres in rough terrain means something which feels a bit more solid under you is of benefit. The tapered steerer and larger diameter fork blades give a notably firmer ride up front, which is offset in the comfort stakes thanks to the big, soft tyre. However it feels very confidence inspiring and much more solid when being pushed to the limit than a straight steerer fork. It also means that the frame will be compatible with the few available suspension forks which will take this tyre size.
Chainstays are kept as short as possible (439mm with EBB in rearmost position) while still allowing for use of a front derailleur with a double ring chainset.
Frames will be produced in three sizes from medium to extra large - suiting riders from around 5'6" (168cm) to 6'6" (198cm). They will be available in once colour scheme only - daybreak yellow with a black panel and red logo.
If a 'stretch goal' of £20,000 is reached then one additional colour option will be added. Let me know what you think that should be! The final decision will be determined through a ballot of the backers.
Production frame and fork sets will retail at £595 GBP - if you back this project in an amount of £400 GBP you will receive a Singular Rooster frameset (frame and fork) in the size of your choice. The additional reward levels should cover other permutations of shipping destinations and associated tax and shipping rates.

Below are a few pictures of the three prototype Roosters I've had made. Feedback from testers indicates I was pretty close from the start, a few little tweaks to tyre clearance and tubing selection and we are going to have a fantastic riding 29+ frame.
REWARDS AND FULFILLMENT
Should the project be successfully funded I will expect to be in a position to place an order for production in mid-April. We are then looking at a production lead time of 3 months, plus a further month for the frames to ship to me. Then it will be another couple of weeks for me to organise all the orders and get frames out from me to you. So if everything runs smoothly and according to plan you ought to see your reward at the end of August. Worst case scenario I can envisage is that it would be late Spetember.
The project is open to backers worldwide - with the exception of the USA. Now don't panic, if the project is successful you will still be able to get your hands on a Rooster stateside via our new dealer Colorado Specialty Velo. They are just getting their website up and running now, express your interest in the mean time by sending an email to firstname.lastname@example.org.
Risks and challenges
In the six years since Singular Cycles' inception I have brought seven different models to market. With this background of experience I would like to think that there are few risks associated with this project. The sole exception being possible production delays. While my suppliers and I do everything possible to hit the production schedule, delays can happen due to issues with other suppliers in the chain, shipping delays, customs clearance etc. Through such challenges I always keep all interested parties and investors informed of any change to schedules and possible delays.Learn about accountability on Kickstarter
