kimbo305 posted:Full face? How are you sighting the contact? This would be rare unless you're using those ball washers that come with BB7s -- maybe the caliper got tilted somehow, so it's top edge of one and bottom edge of the other. Would look full from the top. The Hy/Rd has ver limited visibility of the pads because of the design. As near as I can see from below they are in contiuous contact front and rear, at least at the lower edge of the pads. Impossible to see elsewhere really. I can't detect any tilt in the calipers either.

I guess a question we haven't asked is: if you lift a wheel off the ground and spin it, how much braking force are the pads actually applying? If you go to move the wheel with your hand, is it sticking from the brakes? If it's not seriously dragging I would just go for a couple rides and it'll wear itself down and you'll be fine.

Ok,, I was able to take them in at the shop where I got the pads and we confirmed the e-bike pads the sold me were a little thicker than the normal pads. They traded me for another normal set and that seemed to do it. Nyyen fucked around with this message at 21:43 on Jun 26, 2022 |

How did Thomson get such a solid reputation with such poor quality? I bought a seatpost clamp from them that was at least 3mm wider in diameter than advertised. A $5 no name one was within 0.1mm of spec.

Clark Nova posted:Made in USA pride ( ) going hand in hand with people refusing to believe that 3D-forged Taiwanese stems are better in every way. I think this is spot on. It's similar to how when Velocity rims moved from Australia to USA and the quality went completely to hell, they still managed to ride on that prior reputation for years and years.

I used to run a Thomson seatpost clamp and it was fine, but when I got a new one for some reason they replaced the bolt with a ridiculous little m3 or something. Chucked it in and got a Salsa clamp instead (the poor man's Phil)

Does that say 2.8NM? Why is their torque spec so much lower than every other clamp I’ve encountered?

The only way 2.8Nm is holding my seatpost up is if it's loving welded into the frame Maybe I should replace my Thomson seatpost with something forged, the real way to make a part...

I’m looking for a little guidance on adjusting the suspension on my mountain ebike for the first time. The problem is it has generic components so I cant find directions for it. I’m not even sure if the front shocks are air or spring. I’m looking to make the suspension softer for offroad. Here are some pics: So the rear suspension spring I figured out that twisting it adjusts the length, so I made it longer, to eliminate play it had (the rear wheel would drop a little when lifting the bike off the ground). Not sure if thats how I should have it. Is that the only adjustment on it? But the front forks are probably more of a problem. I have to put as much weight on the wheel as I can to get the shocks to move less than an inch, and it doesnt retract much. I’d like the shocks to go down a lot more and come up the same. The right side adjustment I see just locks the fork so it doesnt move. The left side adjustment, with the plus and minus, seems to adjust how much weight is needed to move it. Im not sure. Not sure if you’re supposed to pump air into them. Not sure if they’re just starting to freeze up or if they’re just worn out. But there’s only about 700 miles on the bike. I know they’re cheap parts so my expectations are low. But any tips will be appreciated.

I’m not even sure if the front shocks are air or spring. I’m looking to make the suspension softer for offroad. Here are some pics: Those are both spring suspension. Turning the rear shock and turning the knob on the fork adjusts the preload on the springs, which is the closest you can get to changing how stiff they are without replacing the springs. It sounds like the rear shock was unscrewed to the point that the spring was loose, causing the slack that you noticed when you picked it up. If you turn the knob on the fork in the "-" direction (should be counter clockwise, like you're unscrewing it) until it stops that will be as soft as you can get it without changing springs.

Saw this bike cleaning video from the Legion bike racing head mechanic https://youtu.be/C73heVMUI_I Seems way off the mark in lots of ways vs. accepted knowledge, and seems especially far from the mark via what I’d expect for a “pro” cycling team. - Putting degreaser all over your rear hub, BB & derailleur pulley wheels. - Cleaning the chain with just a paintbrush with degreaser on it, vs. Immersion in the correct solvents off the bike. - Using an oil based chain lube at all.

With a tool you have to assume you're going to replace important parts or the whole tool regularly and you'll balance the time and resources you spend on maintenance against that.

Pro racing cleaning and mechanic work isn’t the same as regular persons. They’re constantly doing it and regreasing and lubing things and at least in mountain bike XC it’s not uncommon to completely degrease bearings in the bottom bracket for instance and relube with a light oil to lessen the friction. They don’t need that to last months or years, just one race before they tear it down and redo it all again Basically pro mechanics aren’t really working within the same parameters as regular people edit: to be clear, I should have watched the video and did not and it sounds like he's talking about regular 'ol bike washing, I was reacting to the idea that pro mechanics don't know how to wash bikes or follow "best practices" lol Levitate fucked around with this message at 18:41 on Jul 12, 2022 |

wooger posted:Saw this bike cleaning video from the Legion bike racing head mechanic https://youtu.be/C73heVMUI_I That's a great vid and covers race bike prep in pretty good detail succinctly. I don't think I've seen a better presented video on the subject. Park Tool videos with Calvin might be the closest thing, but you'd have to sit through several videos to get this much insight.

Is there any fear the degreaser can creep into the sealed bearings and cause issues? I imagine those are serviced or swapped more regularly, but is that schedule part of why they can just hose down the degreased parts right next to bearings?

I have got a Sora 3503 triple, and a BB RS500 bracket, which doesn't come with spacers. Do I need spacers for a triple crank? There's a seal-side cover type spacer on my current working setup, which could be #6 on this diagram?: http://www.sjscycles.com/Drawings/Shimano/Shimano_Sora_FC-3503_Tech_Doc.pdf Without that cover, I see about 2, 2.5mm of loose spindle when I bottom out the preload cap.

There's a seal-side cover type spacer on my current working setup, which could be #6 on this diagram?: I've done this once more than a year ago but I think Shimano has a special kit of spacers for road triple ht2 cranks and I think it's parts 5, 6 and 11 on that picture. The bb had just the normal spacers for the frame. I think I ended up using just part of the kit in the end because with all of them the lefthand crank would fit too loose. Would the end result be the same with just some spacers under the bb? Probably.

It does mention using a spacer on the NDS for triples though, but it doesn’t say what size it is. There is a Shimano 3mm spacer specific to triple crank sets, so maybe that’s what they’re calling for.

Yeah, 68mm shell. And my current (I think crunching) BBR60 bb without BB spacers fits with that cover spacer installed.Havana Affair posted:I think it's parts 5, 6 and 11 on that picture. I have 5 on the DS, I think, but not the 11 spacer behind it. Well, I'll look again. And on the NDS side, I don't have the 5. quote:I ended up using just part of the kit in the end because with all of them the lefthand crank would fit too loose Assuming the RS500 cups stick out the same amount, I should be able to achieve the same preload I had before, which felt ok. Though now I'm curious if maybe it was applying some extra wear to the bearings, given that I've gotten a creak in... 1000mi?
