2 bolts under down tube - what are they for?

bandeja

I have 2 bolts on the underside of my down tube, they look like the same as the bottle holder bolts. What are they for? Surely not a bottle holder underneath the downtube?

Mud guards?

nicklouse

maybe or mudguard.

or just for letting in water.

what is the bike?

Touring bikes generally have 3 bottle cage mounts, one under down tube, useful for extra water or for stove fuel, on an mtb you can mount crud catcher type mudguards (or use it for the above, if you go touring).

crud catcher bosses, 99.9% certain. godsend if you use a front catcher/guard.

afcbian

mine has them too, and I think the holes in crud catchers fit them

Near the head tube they are crud catcher mounts,

Near the bottom braket they are bottle cage mounts.

ricardo666

either bottle cage mounts or for a crud catcher

Mudguards

I have some on my Pitch that are for cable guides.

That's for the 'ski' attachment - vital in this weather

Its a Specialized stumpjumper ht expert - they are near the bottom - almost at the bottom bracket. Too low for crud catcher anyway.

bottle cage then

Hmmm, I wouldn't want to put my gob around a bottle thats hung under there for most of a ride.

Back in the day they were vaguely useful for putting light batteries in, meant you still had 2 usable bottle cages if you were doing 24 solos or sommat.

Bit pointless now really.

Yeah, but if you were on a multi-day wild camping tour type ride you would want the extra water storage - you just decant it. Or you may use it for fuel, as I said.

I've got them on my CX bike - they're too far apart for bottle cages but fit Crudcatchers perfectly

My old 03 Big Hit DH had them there aswell, way to low for a mud guard!!! must be a bottle cage.

Bit strange for a DH bike!!! Must be a Specialized thing

Sometimes these bottle mounts are more for old-school bottle-mount batteries for oldfashioned lights- they're sealed so aren't too bothered if they get wet.
