Marin Muirwoods 29er - internal hub + belt drive compatible?

Hello to those in the know,

Wondering if anyone has experience with the frame of a Marin Muirwoods 29er bicycle, 2010 or 2011 models. I wondered if it could be modified to an internal hub (alfine 8) with a Gates belt drive. I do not own the bike (yet) and haven't been able to see one in person. Apparently to use a belt drive the rear fork must be split to allow the belt to pass through.

Thanks in advance for the help.

Simple answer is you can't fit a Gates belt drive to this frame. The reason for this as you note, is that the belt needs to be fitted through a slot in the rear triangle which this bike as stock doesn't have.

You could get just about any bike modified for this, but suspect the cost would come out similar to buying a frame designed for the belt drive in the first place.

The same really goes for the Afline, would be much easier to get a bike with all this in place, rather than attempt to modify a newly purchased bike. This has several advantages over doing it yourself, including support from a manufactuer, all the bits are there / fit, and warranty.

Thanks for your quick reply. It seems there is much involved in modifying any bike for a gates belt and it should not be tried at home unless you're a professional. For example, and for those who might be interested, I just found this explanation of the process of modifying a 29er (Raleigh) to accept an Alfine 8 hub and Gates belt drive.

Frames for belt drives really have to be purpose-built to be practical. Modifying an existing frame can be done but isn't practical from a cost standpoint. Switching from a derailleur to an IGH is done more easiy but it's still an expensive conversion.
