I just installed a gigapipe bb in my 5.0 frame and the bb does not spin freely anymore. It still turns, but it takes quite a bit more force than it did before installation. Upon closer inspection, it seems that when i tighen the driveside without the non-drive cup in.. i can tell that it pulls a little to one direction. Installing the non drive cup becomes very difficult when the drive side is tight. Does this mean i need to get the bb faced? as it seems something might be uneven. ANyone ever experienced this?

dunno much about your specific problem, but i had to get the drive side faced on my raven 4.0 to get the BB to seat correctly.

Facing the BB shell only makes sure the faces of the BB shell are parrallel,however if the BB feels like it is pulling to one side, it sounds more like the threads may be a little crooked in the shell, have a GOOD shop use the facing guide cups to see if the threads are straight. we used to install the guide cups into the BB shell then slide the facing tool in, if the threads are crooked the tool won't fit together properly. if the threads are cross threaded already, they shop should be able to chase the shell and make it as good as new.

well, after a night of leaving it alone, it seems to have corrected itself.. maybe i was tired last night.. it all seems to line up now, bb still turns really heavy... *sigh, with cranks on it it won't be too noticable, hopefully it isn't hurting anything :-D. i would take it to a shop, but we have no good shops in peoria. I'd have better luck taking it to a machine shop probably.

honestly, ive had nothing but trouble w/ the truvativ bb's, our shop has completly removed them from stock, we only cary FSA platinums now, and theyre much nicer to install/adjust, and weve had no complaints like weve had in the past

How exactly do you adjust a sealed bb? Can you easily pull them apart?

hey, if you had this problem, i would strongly recomend you to take out your BB and check the threads on your BB and the shell itself, I had this problem also on my 5.0, and I just found out all my threads are jacked up now. I found this out before it was too late, so tomorrow I am going to get it faced and laced at some some which is suppose to be awesome, but check them before it ruins your bike!

Damn...you scared me with this thread cauase I was getting the gigapipe for the Raven 5.0 I just got in the mail Friday =Þ Thank god...now I can sleep!

Maybe I'll go with Race Face or some other BB's instead...

i think its frame dependent... not bb... if ur frame's threads are good ur fine, if not.. u need to get them chased and maybe faced if ur bb doesn't sit right in the shell..

well the shop i took it to said the shop they told me to take it to (Richardson Bike Mart in Frisco)[richardson bike mart is where lance armstrong use to work before he was famus] they dont cary the truvativ BBs anymore. but if i had my camera i would take pictures, but it was stolen. the threads in the shell are all square looking and stuff, almost like the BB had made them that way, and also the first few threads on the BB were pulled out of place or something, i dont know, but its all crazy like, but i can get the shell fixed, but i might have to get a new BB or i can shave off the first few threads and it will go in

aj2four0
11-28-2004, 11:06 AM
wow, thats crazy.. i'll pull mine back out again, but it seemed like they threaded really hard toward the end, but when i took them back out the threads looked okay.. I'll check'm out when i pull the bb again. Thats kinda freaky..

CoppellStereo
11-28-2004, 02:52 PM
yeah, i took my frame to the shop, and they said the threads were definately crooked (only the drive side was crooked, the other side was fine), and now my frame is unridable. :(

cant you just retap them?

CoppellStereo
11-28-2004, 03:12 PM
they did retap them, and since the threads being crooked at first, it cut away too much of the metal, which is what i thought would happen

11-28-2004, 03:36 PM
so what happens now....?

CoppellStereo
11-28-2004, 03:37 PM
but it seems more than just the threads are crooked, the whole side of the rear end seems to be crooked also, even the brake boss is not how it should be, and my perfectly dished wheel sits to one side on the frame. :(:(:(

CoppellStereo
11-28-2004, 03:39 PM
i have no idea what happens now, we will have to see, hopefully BT will replace it since it is a manufacturing error, but i dont even really know if they have a warranty or a guarantee or anything like that

aj2four0
11-28-2004, 08:32 PM
i'm having those 2 issues as well.. my rear end is also crooked.

my bb is in right now, but its not happy... and my rear end is crooked, but if i tighten down one side before the other my tire barely rubs one side... we'll c what BT says? :'(

on a side note, roman is still a pimp and is workin hard to get these issues resolved.

BT's seem to be having a problem with that brake boss issue. I know it happened to toosicks on two different frames.

godammit. i received a bt a week ago and haven't had a chance to build it up yet. seeing all these issues i decided to see if my rear end of the frame was crooked and...my wheel won't even fit in the dropouts. it's like the rear end is spaced like 10 mm too small and the dropouts are crooked.

fuck.

what is this brake boss issue? one of mine is welded on slightly crooked, but i didn't figure it would be an issue.

Have fun with adjusting your vbrakes

well, i have the magura model, so i figured that wouldn't affect adjustment too much.

Tanner
11-28-2004, 09:20 PM
Oh, no, probably not then. I assumed you had the vbrake version

11-28-2004, 09:29 PM
my maggies fit fine... cept the fact that the rear wheel fits kinda crooked ;(

i wonder if mr. BT will even figure it worth his while to warranty all these frames.. sure hope so :-D

Errr my BB seems funny...I talked to the shop & they can get that re-threaded easily. As for the rear part umm I don't know.

Ya Roman has been great though in every way. Very helpful. Hopefull BT will correct the problem...

If you have a problem with the frame please get in touch with me.

CoppellStereo

hey, it may look easy to rethread, but the way it was done crooked, will take away your threads completely like what happened to me.


what i think it is BTs frame builder holder thing is a little off for the drive side, so the whole drive side of the frame is off just from some small offset in their building jig.

built mine up a few days ago and have gone on several rides since.... rear wheel is dead center and the bb threaded in just fine. the threads looked good before I put it in too.

Just thought I'd throw that out there so that people dont think that all BTs are bad.:bigthumb:

I would never say BT's are bad...there will always be manufacturer glitch with any bike. In fact the bike I had from Specialized (not trials) failed twice within three months due to their error & the rear disc tab kept cracking. They did replace them for free with a better frame.

Not to mention BT's are very sexy looking :)

yeah, its nothing against BT or Roman, the bike itself is so awesome, i am just having a few minor problems that are most likely individual to my bike

hey, im just wondering what happened to you guys and your frames.

I'm kinda pissed off right now cause I need to stop spending money but it goes on and on.

BT 4.0.. perfectly dishless wheel sits to the right. if my pads were new i wouldnt be able to fit my hs33 on. also i have to stretch my dropouts out about 7mm to fit the hub on.

and my BB keeps coming loose on the drive side after like 4 hours of light riding. I only weigh 60kg.I'm just trying to get used to the bike. I don't know where to go/ who to trust / what to do. the bike store charged me 20$ a pop to get it tightened (I feel like a dick)

besides. its like the sexiest bike ive ever seen, i just want to ride and concentrate on my technique not fussing over fixing it constantly. help?

CoppellStereo
03-28-2005, 03:24 AM
i had all the same problems you have on your 4.0 as on my 5.0.

for the wheel/hub not sitting in the right place, i just redished my wheel so it sits properly, but since i have v brakes, i can adjust the brakes accordingly, unlike the maguras, the rim would sit wrong and rub on one side.

for the drop out streching part, it kinda works it self out (applying a bar and bending one side out[preferably the side that your brake pad rubs on])

For the BB coming loose, i took mine to a shop, and they said there was something wrong with the threads (crooked) so it would keep coming loose, they tried to fix it, and when they did, it cut out all the threads, execpt like 2 close to the center, so i aligned my BB in pefect with JB Weld on it, and it works perfect, i am not the best rider, and i hit my bash really hard (broke a bashgaurd already on it, and yes, the JB Welded side is the Drive Side) and the BB has shown no signs of coming loose, even after crazy hard hits.

if you have any other questions, let me know, but other than some minor problems, the bike is awesome :bigthumb:

Just for the record, I recieved a total of three BT 4.0's and the one without manufacturers defects had a not so round headtube, from being dropped during shipping. I never got as far as even attempting to screw a bb to any of the frames because once i saw that my rear wheel and brakes wouldn't fit i stopped the build.

Roman is a good guy to deal with, and i had no complaints about him. Hopefully BT has already increased their quality control.

No problems with any of the Australian BTs I think.

I wish i could spend all my moneys on trials but my band said they will kick me out if I don't buy an uber good drumkit.

Not to be a "Me Too" guy, but I've had two different BT 5.0's now, a white one for a few months and then switched to a black one because my buddy wanted to buy my white one rreally badly. Both went together flawlessly, and both have had no problems since day one. I'm totally satisfied with the build quality of my 5.0
