Working on a 29er for Jason….
The design is built around a 100mm suspension fork, a 350mm seat post, and a 90mm stem. The stem needs to be a 10 degree model installed with no spacers and oriented to produce the required drop for his long and low position.
The bike will be built with Paragon sliders and include all required cable guides in case Jason later wants to run gears.
I will be putting the seat post clamp slot in the front. Jason plans to top the build off with an aluminum seat post clamp.
For guides, I am putting a full set even though the bike will likely initially be a single speed. Three rear brake hose guides will run along the top of the top tube. Two sets of twin cable guides will run across the top of the top tube although these will not be used when in single speed mode. A cable guide will be on the seat tube for a top pull front derailleur if he decides to go with gears. The seat stays will have two hose guides for the brake on the non-drive side and two cable guides for a rear derailleur on the drive side.
The extra guides will be a little ugly when unused but they give the flexibility for times when Jason may want a geared 29er for his stable.
Three water bottle mounts will be provided (down tube, seat tube, bottom side of down tube).
The frame is built with a mix of 969 and 858 butted tubing for a total weight of 4.6 pounds.
