Many of you will have seen the thread from monchito, who has posted some of his stuff on this thread, about making his SRAM redinto 11 speed. (viewtopic.php?f=3&t=110303&hilit=monchito)
I thought, yeah why not, so here is the start of my process turning my SRAM in 11 speeds.
Unlike monchito, instead of adapting the hub, im going to attempt to adapt the cassette, out of reasons to swapping cassettes onto other wheels, and also machining skills. So i decided to piggy back the bigger cog onto the back of a spare Red cassette i had in the garage. I found somespare cogs that were eligible for this. So im turning my 11 - 26 cassette into an 11 - 26 +2 or an 11 - 28. I started by measuring the distance between the cogs, then made sure i could use the hub with a two cross spoking (this is wider than direct pull spokes) after an "Official maybe" i went ahead with it. i figured that if i used the small spacers from a chain it would space my new cog nearly perfectly from the inside edge to the cassette. so i pulled them off my old Sram red chain.
this shows where the new cog will sit
here is it with the new cog placed on.
So i lined up the cog with the free hub splines, drew on where it was going to go so i could place it easily. I now have to drill the back of the Sram and tap it, i might also run a nut on the inside as extra precaution. Ill drill the cassette while having both cogs on a free hub to make sure its in the right spot, then i will remove the splined section of the new cog (marked by the blue circle on the above photo, and then using counter sunk bolts attach it to the outer of the cassette using the spacers from the chain.
this is the placement of the chainspacers
once attached and trued (like a wheel) ill mount it on the hub. TECHNICALLY it should fit any exisiting shimano 10speed free hub. the only for seeable issue is contact with the spokes. once i have a cassette functional and tested, (ill adjust the 10 speed lever to work on the cassette except the smallest 11T cog as it keeps standard spacing) i will mill the section from the lever internal to accomodate the new cog. Then it should be functional.
Im waiting to use the mill from my old school, as its summer holidays here. then i should be all go. Here is a 11 speed SRAM red Powerdome+1 cassette teaser photo for you all!
ENJOY, and suggestions hit me up!
