- Dub Step…. sram crap

No surprise that sram yet again can’t put proper seals on😂Posted 1 month agomartinhutchMember
Have you managed to get the cranks off? Mine needs replacing & I can’t get the bolt undone for love nor money.
I had this issue on a brand new carbon frame. Even my LBS failed with a pneumatic gun. Eventually needed to stick an old pedal on the NDS, stick that in a vice, pivot it so the back tyre was wedged against the workshop wall, and got my lad to hold onto the frame for dear life while I heaved on a long bar stuck over the allen key.
When it eventually let go, it sounded like a gunshot*. It was at this point I decided to go back to Shimano as soon as possible. 🙂

Just this week I’ve had to hammer my longest 8mm Allen to get a dub crank set bolt undone. When it went, is sound like it had been over tightened, even though I installed it with a torque wrench. Saturated it with spray grease when I reinstalled, but it still sounded like I was over tightening it even though, again, I was using a torque wrench.Posted 1 month ago
“When a compound is applied to a threaded fastener that will be tightened to a specific torque setting, the torque setting will require adjustment to allow for the lubricating effect of the compound. Failure to do so can result in incorrect tension in the fastener.”Posted 1 month agobluearsedflySubscriber
Had this on my dub XX1 crank when replacing a shagged dub bb. Ended up with the nds crank wrapped in rubber sheet rested in soft vice jaws opened slightly too wide. It was a nervous few minutes.
It was only tightened up to 30nm as I’d read of the problem previously.Posted 1 month agoOscillate WildlyMember
had the same on sram dub x1 carbon cranks, initial install, so fresh with no grit and a bit of grease, torqued up (as my previous sram dub descendant carbon cranks) and forgot to do something so had to immediately take them off, and stuck, was absolutely impossible to budge, hammer came out, dad holding bike and just about got it budged, made a awful sound when releasing!
so super lubed it back up next time, and its been easy to get off since like the descendant dubs were…no idea what causes it tbh
as for the BB ive actually had real good miles and horrid winter conditions for the price, still smooths nicely, the stupid little blue seals are a awful design though as they literally fall out of place on removal and installation!
better than the piece of shit hope one it replaced anyways!Posted 1 month agoOscillate WildlyMember
weirdly after this thread, and me saying like others the cranks were a pain to remove first few times on DUB
last night my d/s unscrewed itself off the spindle, no idea how, it was only kept on by my chain guard not allowing it to move any further over
I know I tightened it up last time so its somehow worked itself loose…..
actually had a feel of the bearings too whilst it was out, DUB bsa threaded new in September this year, endured a long wet/plenty of washes winter and the bearings still spin smoothly, not great, but no rough, more actually a bit too freely so may try bang some grease in
but for 25 quid for 5 months constant wet use I don’t think is that bad personallyPosted 1 month agoYakSubscriber
I reckon dub is a bit worse that HT2, but not that much worse. My wife probably gets 2-3months out of them in the winter and a bit more in the summer. Yeah it’s a pain getting sram cranks off. I use an old handle bar over the hex wrench for leverage with the other pedal jammed.
One slight advantage of dub is that you get early warning of failure when the preload collar needs a tweak every ride. Then you know to get one ordered in asap.
Anyway, bring back UN72s…Posted 1 month agoductionsSubscriber
I had the same issue getting my SRAM 1×11 chainset (previous generation) off my bike. Could not undo the drive side with an 8mm hex, so I had to precariously position the bike frame so that I could use my body weight to undo it. Like others have said it sounded a bit like a gunshot when it finally budged. So I don’t think this is exclusive to DUB.
I’m after a new chainset for my SolarisMax which I already spec’d with a 30mm Hope BB. Was thinking of getting a SRAM SX Dub chainset for about £50 and the Hope DUB conversion kit.
Or spend even more money on the GX groupset (and still buy the Hope adapter).
Or either of those options, but switch to a DUB BB (and buy the BB tool), sell the Hope BB.
Unless there are better Boost 30mm chainsets that anyone could recommend under £100?Posted 1 month ago
