wellgo MG1 service question

canada16

Hey

I have upgraded my front mech from an LX to a XT and got the bike shop to fit it.

Now when I am on the bottom ring of the cassette and the bottom ring of the front, as if I was going up a steep hill, the chain rubs against the front mech. Well took it back to the bike shop and they said I should never be using that combo and thats why it rubs, but the thing is, my LX never did that,, It also happens when I am in the highest gear as well, with the chain on the top at the front, hope that made sence... :oops:

Next question, what sound would you hear if your BB was on its way out, or if your pedal bearings were done? I am getting this annoying click and its getting worse, it was one per revolution now its click click?

Can I service this stuff or is it better to buy new? The pedals are MG1's and the chainset is hollowtech LX 2008.

Sorry to be a pain guys, and thanks so much..

correct you should not use the two small cogs as rubbing WILL happen and it put undue strain on the chain.

you should also never use BIG and BIG for the same reasons.

bb depends. remove the chain and spin the cranks if you hear/feel a rumble then you will know.

All explained on Parktools.

Bottom ring front and bottom sprocket back - for going up steep hills, you're in the wrong gear (small ring front/big sprocket back for scary steep hills, ie. 1st gear), as said above it will rub, thats why you have so many different combinations of gears to use.

Thanks guys, kinda feel dumb now... :oops:

The click only happens when pressure is applied.

When I am just pedaling like two lovers on a tandem in a sunny meadow. then its ok, but only when I am going like 15-20mph that's when the clicking happens, and would not be able to do that without a chain..

Thanks again

Oh sorry, you mean a rumble with the chain off.. LOL, there I go being dumb again.

So if its the BB it will tremble, if its smooth then its the pedals?

Chaz.Harding

It may feel stiff, or have tight spots.

If the pedals spin freely, and aren't loose, then it's probably not them.

It wouldn't hurt to dismantle your pedals, pack them with grease, and re-construct them, making sure they are adjusted correctly. If you still get the 'tick-tick', it's probably the BB.

How long have you had the chainset, what sort of riding conditions do you ride in, and how well you have maintained it, are all relevent questions. If you ride everyday in muddy feilds and only clean your bike with a pressure washer, the bearings won't last as long if you were more carefull cleaning.

Either way, hope this helps!

Hey

I am very anal with my bike as I like it clean, and never use a pressure washer as dont own one.

I lube and everything, I only ride light XC, cwmcarn, afan, castell coch.

I have had my pedals for almost 2 years and they are mg1's, so they might need some grease.

Will take them off and have a go. Is there a type of grease I need or just anything will do?

some thing like this should be ok there are loads out there pick one ans see how you get on with it..

Cool thanks man.

Does anyone know anything about the wellgo mg1's.

Are they easy to take apart and service, I am not mech inclined, you should see what I did to my rear hub...

Thanks

pedros syn grease is good stuff for bearings, my v12's are loving the stuff anyway

"rock n roll" superweb grease gets alot of good praise on bearings too, apparently it goes all stringy? which they say is good on bearings?

canada16

OK

I have taken the pedals off and pedaled the bike with no chain and it seems smooth, so its not the BB.

Taken the caps off the end of the wellgo's, not should I just pack that with grease as it looks dry, or should I be trying to remove the inside of it as well?

I cant figure out how to remove the inside though?

Thanks guys

Chaz.Harding

Is there not a small nut behind the end cap (on the outside of the pedal, when attached to the bike).

Take the nut off, remove the pedal body from the axle.

Also, forget that daft 'ceramic' grease someone else mentioned, get some Finish Line Teflon Grease, much cheaper, basically the same. Good stuff - sticky, water repellant, and lasts aaaaages. The 1lb tub will probably be a good size if you intend on doing your servicing more often.

Hey

Thanks..

I can get into the space its inset a bit, the size of a p piece, and none of my wrenches will fit into the slot?

So many people recomend MG1'S but not too many people responding

I dont think I will be able to get that nut out, TBH

I've just never had to even look at my MG1s since I fitted them, they're sealed bearings IIRC so no regular servicing. So, sorry, I do regularily recommend them partly because they've been totally maintenance free, for me.

Do you have a pair of random pedals, the ones it came with frinstance? Obvious thing to do is to try those.

Chaz.Harding

You won't get a spanner in there. You'll need a socket. 7, 8 or 10 mm. Probably 8, like my V12's.

Take it off, slide the pedals off, and assess the condition of the bearings. If they are horrible, just buy new. The bearings will have a number and letter code on, this is the bearing's name. You can order what you need through Timken, or somebody similar, if there's not re-build kits / bearings readily or cheaply availible.

If the bearings seem ok, pack with grease, tighten so they are SLIGHTLY stiff to spin, and back off. They won't spin for ages (like I guess they do currently, as they will be filled with grease, but they will spin easily, and not be stiff.

It's easy, honest. You'd have to try really hrd to f*ck it up!

Chaz.Harding

A good way to check, is that there is no 'end float'. IE, the pedal shouldn't move forwards and backwards along it's axle. Only spin around it.

But you already knew that, right

canada16

No I didnt.

One of them does move in and out, not forward and back?

The other one is a bit more solid, but not much.

I have tried every socket and they are not thin enought to get into the space.

I have put a bit of wet lube in them, cleaned them and screwed them on nice and tight.

Will have to wait and see.

Chaz.Harding

If none of your tools fit, how did you tighten it up??? :shock: :roll:

Anyway, if they dont slide up and down the axle, will be an improvement. Get around your mates / local garages / LBS and see if you can borrow a tool just to get your pedal off the axle, re-lube properly with some decent, thick grease, and re-assemble. Honestly, will make a world of difference.

looked in the FAQs?

same idea for the MG1s

canada16

I got them off with a spanner.

I I got the first cap off with an alan key, then after the alan key is a little hole with a nut in it that is about 5mm down in the pedal and prob 1-2mm from the wall, so very thin. and a socket is too thick.

Will have a go tommorow as fitted some kcnc jockey wheels, look sweet and 16.00 for two.

If this does not work, will ask lbs if I can borrow some spare pedals.

Will check that link out as well nicklouse.
Im sure its the pedals now, as the Cranks were very very smooth and turned nice,

Thanks

canada16

SORTED !!!!!!!!! :P

Thanks all

It was my pedals, put wet white lightning in them and put them upright for a few hours, and put them back on tight.

Rode this morning and nothing.

Two months of click click with every pedal, and it was something so simple.

NICE 1
