Shoddy Mechanics - Just venting

Page may contain affiliate links. Please see terms for details.
When i ordered my Bianchi Sempre frame, despite my original plans to build it myself, my LBS offered to do the build for me. Seeing as i don't have a headset press, or a tool to install the OS ultra-torque BB cups i thought i'd take them up on the offer.

When the frame arrived, i took in my current bike to have the parts switched over, having wrote down exactly what i wanted them to do and supplied a few other parts (new stem on the new bike).

My first shock came when i went to pick up the build and the old frame. They had taken the headset cap from the old build and put it on the new bike, leaving me without a headset top. Now, anyone who's bought a frame before knows that frames come with headsets, but they had simply decided not to include the top cap for my new frame and instead used the incorrectly fitting one from my old bike. After a bit of arguing they said they would do me a discount on a headset cap.....and then sold me the cap that was meant to come with my new frame.

Second shock, i asked for the old stem from the original bike. At which point they looked worried! It turns out they had put it in the glass counter display case and marked it as for sale for $50!!!!!

Now, the most recent shock came last night. I was giving the new bike the once over and noticed that there sounded like friction when i turned the cranks, so, i took off the crankset to take a look.

It seems that instead of fitting the OS Ultra-torque cups, they fitted the new Power-Torque cups. That may sound like a subtle difference, but my Super Record UT crankset has expensive ceramic bearings fitted to the axle, whereas power torque has the non drive side bearing in the cup. They also have a different tensioning system. Basically, the two are incompatible. To cope with this, it seems they removed the ceramic bearing from my non-drive side crank and then fitted a hugely strong spring washer to take up the slack. This springs tension was the cause of the friction in my BB and the lateral force seems to have destroyed the fitted bearing in the power torque cup.

So....now i'm faced with the repair. They never told me what they'd tried to do and i'm shocked that they just didn't order the right part. The ceramic bearing they removed wasn't mentioned or returned to me, so i've had to order a new set of bearings, the right cups (they charged me for the wrong ones too despite this useless hack). I'll be going to a different LBS to get them fitted.

Worst (or best) of all. I'm venting in CC, because i can't vent at the shop. They've since gone bankrupt and no surprise if they are treating people's very expensive pride and joys with such bodge jobs.

Anyway.....i'll be $300 down, but am sure i'll get it running sweetly soon. Moral of the story......
1) If a job's worth doing, it's worth doing yourself.
2) CC has collectively the 1,000x the experience of any single bike mechanic/cowboy. Anyone can do anything with the help of CC.
EDIT: 3) For reference, Ultra-torque and Power-torque are NOT compatible/interchangable

Anyway, rant over. Thanks for listening

Absolutely no-one will take as much care of your bike than yourself. I think though you have had a particularly bad experience. Sorry to read your tale Tollers.

Don't tar all us mechanics with the same brush i treat my customers bikes as if they where my own, but i do agree there are a lot of cowboys out there.

I've not seen PowerTorque in the flesh but having watched the Campag promo video and removed bearings from several UT cranks in my time, I'm amazed that this mechanic managed to get it to work at all. The spindles on UT cranks are slightly wider where the bearing sits which means that he must have hammered the NDS side into the assembly to get it to sit properly - is this where he put the spring washer (between crank and bearing rather than bearing and cup)?

The supposed gain derived from CULT bearings would be lost by using Record UT cups as the rubber seal on the inside adds drag in tiny amounts....just like the savings made by ceramics. SR cups should be used otherwise you may as well have a Record crankset. (It isn't clear in the OP).

Thanks for the reply Will.

Yup. I'm amazed how he got it to work....although seems it was less than 200 miles of working before the powertorque bearing failed. I expect he did hammer it, or just use the UT tightenting bolt to pull it in......although i think it still didnt really allow the teeth in the middle of the axle to mate as tightly as they should. He then did indeed put the washer between the crank and the cup.

The cups i've ordered aren't record but the standard OS fit as my BB is BB30 rather than English 68mm.... http://www.campagnol...newscatid_3.jsp Hopefully, they should give me the CULT smoothness back :smile:

I find headset caps are a source of regular displeasure. There are two bike shops I use - basically one for mtb stuff and the other for road stuff. Both shops are reasonably competent if sometimes a bit careless (e.g. chip out of the paint on a new fork which looks like someone dropped a spanner :angry:) but both can never get the right headset cap for the headset they've fit. Currently the road bike they fitted a new headset to has a Campag headset with a Cane Creek cap? Until a recent refit, the mtb had some anonymous cap on a Token Carbon headset. Do they collect the nice headset caps for themselves, are there so many rolling around in the workshop that they just pick some random one?

With the mtb, I'd been thinking about a red Chris King h/s and there would have been trouble if I'd picked that up without it's matching bits :biggrin:
