Help with Seven Sola Frame build

[caseycuda87]

Hey Guys,

Pretty new to posting here, but frequent the site quite a bit. Im looking for some help with my Seven Sola build. I will try and attach a picture. Currently its a frame and some parts hanging on, but ideally I would like to use the XTR crank that has been set up for single speed to do a 1x10 set up, run a chain guide and hopefully it all works. Anyone have any experience with this. Hopefully the picture can speak to what I am talking about. I am also one of those lucky guys that has come across a white brother sc70 fork, and would love to run disc brakes up front, but with no adapter in site for their proprietary 22mm leg tab. Thanks in advance for any help.

Re:

You should be ok, if you do have a problem dropping the chain you will have to go with a clutch mech and a narrow wide chain ring.

Clutch mech, either shimano or SRAM, IMO are superior to any chain catcher device - you would need to use compatible shifter.

Also can use narrow/wide chain ring but this would need to have cassette with sprockets that have even number of teeth.

RE: disc brake adapter - can you post photo of what is there currently? you may be able to modify an available or adapter or be able to make one if it is simple.

Re:

Thanks, yes actually purchased an XT shadow plus and 10 speed long cage shifter for the rear. I am going to try and make a 11-42 rear cassette work and add the longer b screw or adapter if needed. Attached is the picture of the disc brake mount. As you can see it's a bit different. I have also heard this may require a special hub to run that was proprietary to White Brothers. If that's the case, xtr rims brakes will do just fine.

re: hub - that depends on location of the disc brake tab. I can't see why you cannot use a standard disc hub with an adapter.

An IS calliper may need an adapter that is offset in two planes (see example in top right) whereas for post calliper is one plane, you may even be able to use an off the shelf (see top left) but need to drill one hole. If the offset is too small, then a plate of alloy with suitable drilled holes would sort that or simple washers to space it out.

fitting a post calliper, find a more chunky adapter and drill hole (yellow mark in diagram below)

fit calliper needs to go inboard, then use washers and/or shims to move it in, If it is too far in, then you are a bit stuck.

Re:

That's a great idea. I think I have a few adapters lying around to give this a try. I'm guess a drill and tap would be needed.

 

[02gf74]

Yes, drill and tap M6.

I realised that after posting last photo that the calliper may not be in correct position over rotor, in which case you will need to make adapter from alloy plate.

Search on here for how i made adapter for a klein frame, youd be doing similar.

Re:

Right, or if I just drill a new top hole and match up the bottom, that should put the adapter where it would need to be originally.
