Did you just ShartQ?

You can jam a small flathead screwdriver in between the arm and the nut, catching the slot.

Ive been trying that sort of technique for the better part of an hour with various screwdrivers and other wedgey things. Guess i’m buying the tool

This is the one I’m thinking of:

some also have a 10 and 8 or 9 mm box wrench suitable for fender hardware in a pinch

cousinmosquito · January 9, 2022, 4:59am

Yeah. If it’s flipped it looks like there is room for one of those. I wonder how long I’ve had my one of those for.

My Sugino chain ring nut tool has done it for my hidden bolts, too.

Yes

I bought a chainring bolt wrench almost twenty years ago, have almost never used it, as predicted by my conversation with the mechanic i bought it from:
me: these things work better than a big screwdriver?
mechanic: nah, not really
Me: oNe WrEnCh, pLeAsE
Mechanic: literally rolling eyes as he rang me up

karl_dandleton · January 9, 2022, 2:42pm

but they totally do work better because they have reliefs for the male part. everyone should own one.

jeffro · January 9, 2022, 2:50pm

Yeah, least bad tool for the job. But still not great.

I like this guy. SUNLITE Y-Type Socket Wrench, 8-9-10mm https://www.amazon.com/dp/B000AO9Q2Y/ref=cm_sw_r_cp_api_glt_fabc_4M23GGD21YM2315SQHJ8

karl_dandleton · January 9, 2022, 3:04pm

oh for sure. but this can earn a spot in a saddle bag. all allen/torx is the superior way to fasten but wouldn’t work well for hidden bolts

rancid_burple · January 9, 2022, 3:39pm

I was frantically looking for mine last week and couldn’t find it. Just realized it’s in my track bag because that used to be the only time I ever needed it.

bward1028 · January 9, 2022, 3:53pm

i ususally put a little outward pressure on the chainring so that theres some friction on the bolt, then make quick sharp turns of the allen wrench to tighten

anon24974279 · January 9, 2022, 4:27pm

^this

karl_dandleton · January 9, 2022, 4:32pm

agreed but once you need to loosen a stuck hidden bolt not much else will suffice

VT_regularbike · January 9, 2022, 5:16pm

I may be in a different camp but a tiny dab of loctite in between the inside bolt and the chainring/spider then letting it cure before you fully torque it has worked well in the past for tightening up one I couldn’t get a tool on.

Master_Stabby · January 9, 2022, 5:38pm

They’re a real shop… in Indonesia.

yonderboy · January 9, 2022, 5:53pm

That’s where I used to keep mine, until I lost a back in the infield grass during a gear change. Then I put the knurled nuts on the tarck bike.

I still replace all the bolts on my cranks with the Sugino steel jawns.

asterisk · January 9, 2022, 6:11pm

I remember coming very close to picking up one of those fancy VAR tools before just c-clamping the Sugino version of the little wrench to the back of a particularly stuck bolt.
