Hey all -

I'm normally the type to figure things out myself, but need some quick advice. I need to swap out my fixed cog and chainring - what tools do I need to do this job? I've currently only got a fairly small selection of tools, so I'm probably going to need to buy the tools to do the job. Much thanks.

Peace
Owen

lockring tool
chainwhip
6mm allen wrench (or is it 5mm?)

Thanks. Also, I'm switching from 3/32 parts to 1/8 cog & chainring if that makes a difference in tools.

then make sure you get a 1/8" chainwhip. it'll work for 3/32" too.

Again, you don't *need* a chainwhip, especially since you can make your own out of spare chain. But the rotafixing technique works great. You basically let the chain sit around the bottom bracket shell and the cog (hand tightened), then double up the chain by the cog and turn the wheel to tighten:

So a tool like the Park Tool HCW-5 (https://www.parktool.com/products/det...5&item=HCW-5)?

This is to get the rear cog off, correct?

Is this for the chain ring bolts? I have a multi-tool that I used to tighten the bolts on my current setup - is this sufficient or should i get something more for the job?

Thanks for the help.

this is the tool used most often. There is also an "adjustable" one that has a hinge but it's not needed usually. The HCW-5 is fine.

Get a set of metric allens at home Depot, from size 4 to 6 at least. You can get a lot more torque from them than a multitool.

I think the Hozan lockring tools are much better than the Park ones



Top are the fancy pliers, bottom is the the hozan lockring wrench. Both are awesome. In the middle is the DuraAce lockring/chain whip combo which is so-so (known some to love it, some to hate it).

Definitely spend the extra dough on the Hozan wrench. Such a good investment.

i have the durace combo and love it, the lock ring tool is great, and the chain whip is also great, it has a little spring that keeps the loose end of the chain from swinging around and whacking you..

plus its one tool with two uses, saves space?

i concur. the park tool sucks.

Have and love the DA multi tool.

thanks for everyone's help...i ended up getting the combo whip/lock ring tool and a basic 6mm wrench. should be a fun upgrade/repair.

short story: i was going to have my lbs do the necessary repair, but had a bit of a falling out with them. i'm sure i'll be happier doing it myself anyway.

peace,

where did you guys buy the Dura-Ace multi tool from?

Got my new cog, chain ring, and tools and was up and rollin' in about 1 1/2 hours (including dinner!). Doing stuff yourself rocks. Thanks for everyone's help.

Matt T -

I picked up the dura-ace tool from benscycle.net in milwaukee. great shop.

Peace,

Oh, and a tip for newbies like myself - lock rings are on a reverse thread. Whoops! Thankfully I also randomly decided to buy a slightly nicer one when I was ordering stuff.
