Anyone have anything they'd like to rant about?

[singlesline]

Chunk of dry ice on the bolt, blow dryer on the frame.

Worked for my seapost, might work for your bolt.

[Conundrum]

No blow torch. Solder iron on the bolt.

I hate ride wraps. I got a matte one for my new bike and it looks like shit. Peeling it off everywhere except the bottom of the downtube and inside of the chainstays. Bike is metal anyways I don’t know why I bothered.

I wasn't a fan of it on my matte black Ripmo, either. Was very obvious, color-wise, where it was applied but worse, did little to protect. It's so thin that anything more than mild scuffs would go right through.

Has penetrant already been tried on that bolt? If it's galled, does heat/cold work to break that free?

Are those brake mount holes blind holes on that frame, or do they go through?

[XXX-er]

I got no experiance with the matte finish but gloss has turned out good on 3 bikes

How good/ bad ride wrap looks depends completely on how good the application was

and its finicky especialy cutting your own from a roll of 3m

They go thru.

I was going to hit with heat, but since SC is giving me a new triangle I just got the brake off and messed with the bolt for a minute using vice grips and said screw it. I'm probably going to get it out eventually just because I'm curious to see what went wrong.

If you have those brake bolts on the rest of that bike, I'd remove and replace them all with some regular steel bolts.

[jackstraw]

Yeah, was wondering if I should do that. The front came out fine as did the one rear bolt.

And use cup/cone washers on any uneven adapters.

Am I missing something here?
If this whole discussion is about a seized brake caliper bolt, why do you keep talking about how you got the brake off?

See post 6014. cut the bolt head off to get the caliper off.

not really a rant, but if any of you bike shop folk have a chance to go to Sram Tech University classes, do it. I was at a two day class in colorado springs the last two days and it is extremely cool.

back in the day at interbike SRAM intorduced SRAM tech U which seemed like a cool idea, Sram did short seminars every morning of the show, they told everybody at the seminar to mention they had atended at the Sram booth to score a free 971 chain, they also had a draw on a Reeba (which i won) so I'm a bit of a Sram fan boi but tmy point is Sram were very engaged and trying hard

in comparison Shimano smugly told everyone that next year all the bikes would come with rapid rise and they bought some beer

the next spring SRAM had a much bigger presence in the bike lines and no bikes came with rapid rise

I often wondered where the industry would be if Shimano hadn't shit the bed

Sram walking all over shimano is just par for the course these days. It would definitely be interesting to see where we'd be if Shimano could pull off any sort of actual innovation.

(Before the Shimano brigade gets pissy, I'm not making any comment about the actual quality of the products. I'm just saying that Shimano is absolutely terrible at innovating new products that are actually good ideas.)

When is the last time there has been drive train innovation? The dumbing down to one by, or the return to direct attachment to frame? They’re both putting out quality and quantity. Heck, sram should have refunded every dropper they put out for a couple years there and shimano is recalling a bunch of drive trains, but overall they’re pretty bomber. It will be exciting to see if anyone can create a competitive pinion system or some true outside the box stuff over the next decade. A no flat tire that rides as well as a standard tire?

The death of front derailleurs

Freehubs that can go smaller than 11t

Narrow wide chainrings (and cassettes, and pulley wheels)

Wireless shifting

Direct mount derailleurs

Clutches in rear derailleurs


Every single one of those things made bikes better (well, wireless shifting is debatable). In particular, getting rid of front derailleurs made a huge difference - frames and suspension designs are way different now that companies don't have to design around a front derailleur. And with the exception of clutched derailleurs, Sram introduced the modern iteration of all of those changes.

[rideit]

TBF, Shimano had direct axle mount derailleurs long before, and Dh bikes were always designed with one chainring.

Yeah, I mean none of those ideas were original to sram. All of them (maybe not wireless drivetrains?) existed in some iteration or another. But sram was responsible for bringing those ideas to market in a way that was more than just a fringe idea. The modern trail bike owes a lot to what sram has done over the last 15 years, and it owes very little to what shimano has done in that same time-frame.

[rideit]

True.

[singlesline]

More *good* innovation is obviously better, but I'm not opposed to a Shimano that plays a lot of copycat but reengineers things Japanese-style with better durability/reliability and bang for buck.

Deore and SLX are solid 12sp drivetrains. Tolerate poor shifting and poor adjustment. Deore is heavy but SLX is only a few grams more than XT. Cassette prices are also way lower which is nice for consumables...here's an XT for $99

That's sort of their legacy too--they filled the hole that the Euro suppliers couldn't in the American market and ended up producing functional reliable non-finicky stuff. Better than them just inventing crazy shit for the sake of invention.

Shimano brakes are easier to bleed than SRAM. And I prefer their engagement, but that just a personal thing. Maybe I'll like the Maven...is that the name of the new one?
Sram dropper sucked forever, but they seemed to have got that straight now.

Sorry, but gotta get pissy here.
Disagree 100%
I understand what you're saying but but disagree with the sentiment. Innovation can also be in perfecting what's there.
I've ridden every one of Srams "innovations" and none have surpassed Shimano's 12sp XTR.

[jm2e]

The Sram v Shimano black & white view of mountain biking is ridiculous.
Sram’s only real breakthrough innovation to biking was Grip Shift. Every other positive contribution from both brands has been big companies using their massive R&D budgets to tinker with what already exists and tying to perfect what boutique brands started.
You think Sram invented 1x drivetrains? No, but they made it work better and on a bigger scale than the bashwich!
You think Sram invented dropper posts? No, but they certainly tried their damndest to take the fun out of dropper posts.
Big brands perfect the product, perfect the production, and streamline distribution to the masses.
The alternative is that their marketing departments drive “innovation” with new “standards”……….. doh

1x still sucks ass.

There is my rant. Fight me.
