1x8 conversion
« on: March 26, 2009, 12:22:46 PM »
Well I finally did it, I got rid of my front shifter yesterday, my bike ,specialized hardrock comp disc, came with the shifter brake lever combos so I replaced it with a new avid brake lever. then I locked my front derailleur in place.
 
I took it for a ride this morning and it only jumped once when I hit a sand pit pretty hard. so to improve this and keep it from happening often I went to bent's and bought a shinny new unramped chainring (usually used for single speeds or down hill) and a chain watcher to replace the front derailluer. I also plan to remove the small ring and I'm thinking about cutting down my big ring to make a bash guard, I'll also take a few links out of the chain later today if I can.
 
I'm sure many of you are saying why 1x8, why not 1x9. well my bike came as a 24 speed and its not worth it to convert it to a 9 speed cassette, chain, derailleur, and shifter until I need to.

I did the same thing on my big bike.
 
I bought (2) Spot black basguards 34T, (1) Blackspire Mono Veloce 34T Ring, (12) E-Thirteen super long chainring bolts. Then I put it all together on my my cranks and it sandwiched the chain between them. I then ran a Blackspire Stinger chainguide roller off the BB and it keeps the chain tight. Haven't had a slap, jump, or chain drop since I put the rig together.

That derailleur you removed wouldn't happen to be a top pull top swing with a 34.9 clamp would it? If so you wouldn't want to donate it for a good cause would you? Same cause as that fork is going to.

Bikepedia says my bike came with a Shimano Altus FD-M310-6, top swing
 
if it works for you, it's yours, you can even have the shifter/brake combo that goes with it if you need it and it works for you.

update: I took 5 minutes with my grinder and turned my big chainring into a pretty slick bashgaurd. then I took a few links out of the chain and put on the chain watcher/ jump guard. I'll try it tonight and hopefully it works out.

Should have the clamp size stamped inside the clamp. 31.8 or 34.9?
