Hmm well im trying to build a second cassette but to adapt my 11-23 i need to attach a 25 to keep the incriments at sensble levels... I can only find a 24 or a 26, and i dont really fancy a 26 on it


The 23-26 jump would be the same as on a 10 spd 11-26 cassette (just saying). Or are you worried that the 11 spd mod can 'only' handle a two teeth increment?

Anyways: Great work! :thumbup:


My thoughts the step up for my cadence might be a little large... the 11- 23 is 1 or 2 cog increments but a three i think woulod make it less of a race cassette, i really need to find a 25 for it, but if i cant ill run the 26

I like the repurposing. Seatpost, handlebar, and a Parlee FD clamp?

I guess this is more of a hack than a tune but it's light and cheap and will hopefully stop my chain from dropping:

I could save a little weight and smooth the looks by cutting the excess of the bolt, chain catchers and spacer, but at the moment i kind of like the 'frankenstein' look.

Have you thought about, for the part that is on the right side of the chainring, instead have just a small horizontal part going left-right directly over the chain? It would run close to the chain, and right about where the chain and ring meet. For the chain to derail it first has to lift up off the ring, the protrusion would keep it down and on.

Are you talking about my chainguide? yes! I got an existing FD clamp...like Parlee, the rest was old parts left in the drawer, a Zipp aerobar Clip and a Cervelo P2/P3 seatpost. :thumbup: It worked!!!! :beerchug:

Very rigid. I stopped tightening the screw because I was afraid of breaking the clamp, otherwise I would go for it. But still, the guide (vertical piece) it self is really rigid around the chain. First I had in mind to fix the "seapost" part touching the clamp directly without any bridge, but to drill the piece at the necessary angle was very difficult. I also wanted to use a Tubeless valve adapter (removing the core) as a screw, the final product would definitely be under 30g. Because of the bridge I had to find another screw, but couldn't find in Aluminium.

But still...I like the final product. I needed I high mount because of my suspension link (scott spark 10).

Thats good thats its rigid, i dont see why i couldnt build one for about 10 grams or less on th emill with a parlee clamp, but as i run 2x10 on my mountain bike i dont see it being neccessary... :wink:

Good use of spares though :beerchug:

Anyone seen some cool tunes lately? I'm looking at starting a hub prototype....

People that know my bike (see below) will be disappointed to hear I ripped the top of my seat tube ISP while destroying a local descent.
Unfortunately I smashed an earthquake bump and it ripped the thru rod out. Back to my ritchey ISP topper (+123 grams! :( ) because of this I must now start a setback intergrated ISP topper with micro adjustable heights!
