Too much torque. That's what kills transmissions usually.

You broke a steel spindle. Sogood will be pleased...

What model was it?

Nate, you're a heavier rider, aren't you?
Also how many Kms on the BB?

Stop looking for excuses and mitigating factors. Everyone knows steel is prone to failure at anytime and often catastrophically without warning :P Next thing you'l be having us believe Brooks Saddles are comfortable :roll: :mrgreen:

Very pleased you didn't get hurt.

Was it a one-legged pedal the rest of the way home ? Have seen a disabled guy doing this around the flats at Kyeemagh/Wolli Creek, can we assume a fit and able Nate would have pedaled it home ?

Cheers

92kgs...
It was a $300 cell single speed... had about 1000-1500k's i guess? weekly commuter 100k's a week & i treat it with respect.
The stock plastic pedals normally take 2 weeks to crack

Its a cheap POS bike, but i'm starting to call "not fit for purpose"...

Seriously, glad you (Nate) weren't hurt. Congratulations on joining TLL on the high altar! But your spectacular "show-off" in front of the bus shelter crowd made me a tad suspicious. 8)

That's a fatigue crack, except for the shiny bit down the bottom, which was the last bit to let go.

Not good after such a short distance. No odd noies or creaking before the failure?

Good save and glad there was nothing behind you!

Fact is, a $300 bike was never made for a power rider like Nate. I call it bike abuse! :wink:

:lol: Yes, very funny. And of course I have an excuse. I don't defend all steel. You can make anything substandard for strength and durability, even in steel. Cell seem to have a history of "good value" bikes that fail when used as commuters. Eg:
viewtopic.php?f=12&t=17764
viewtopic.php?f=41&t=17766

I suppose if you scape the bottom of the barrel for parts, you are going to get some failures long term.

It looks like the crack was propagating under the crank. To me, that is the most dangerous type of fault as you can't see the crack forming. Steerers have the same problem.

Yes, they had a couple of dodgy batches of handlebars and steerers - 'bars were recalled (my bike - and Nate's roadie IIRC - were affected). I notice that they've ditched that manufacturer (Zoom) in favour of FSA on at least some bikes.

Nate, you should've converted the Team to SS! :wink:

I break stuff all the time Nate, the number of timber steps and ladders on building sites and bike chains is a worry. Being 6'4" and 110kg will test anything so I'm guessing that the bike was in a price range not intended for the 92kg, power and use it's getting. My first road bike a Jamis was purchased because they warrant it for up to 140kg and I even managed to crack a weld on that. I buy Record and Dura Ace chains exclusively now.

Nice to see the guy at the bus stop showing concern for your wellbeing and safety Nate. Did not move a muscle... :roll:

When you have a fatigue crack, the polished area is where the parts have been moving relative to each other and is the first bit that has let go, the crystalline surfaces mark where the last bit let go.

It doesn't matter how cheap the bike is . The fact is that a crank breaking is an unacceptable safety issue. Bike stores need to wake up to this because ultimately they bear the risk.

Glad you pulled up safe from that one Nate and managed to stay upright. It's not the crank that broke, it's the BB axle that broke.

I think you're right. That is really poor and disappointing component life. I'd take it back to Cell and see if they'll fix it under warranty.

My cheapo commuter still has its original plastic pedals after 14 months and >10,000km... I'm heavier than you (and a masher).

Nate clearly has enough power but may get a muscular imbalance with too much one legged training. :mrgreen:
