Mechanics and Fixing Any Questions Answered

I'm fairly sure you don't want that spacer between the frame and the bb cup, as the alba is a road crank. That would be why the cranks aren't spinning freely. Take that off then refit the bb without it.

I'm assuming that the plastic bearing covers that came with your gxp bb are slightly narrower than the spacers that come with praxis bbs which might cause the knocking

vs this

although the internet seems to suggest you can fit Sram cranks in the Praxis BB so not sure why you couldn't go the other way.

65Nm iirc (and I may not, caveat emptor. And was it for the bearing cups or for the crankset? Don’t remember…)

Spacers shouldn't matter (apart from too many), you essentially attach the cranks to the NDS bearing on gxp style stuff.

I feel like I could be wrong here but Sram gxp BB? I've always thought that Praxis Cranks need Praxis BB.

The linked above says these are the compatible ones: Praxis Works M24 - BSA / BB86 / BB30/PF3

Ignore if you've thought of this.

I have a Shimano dynohub with B&M lights that's been working fine for years, and was working fine when I fitted it to a new bike last night.

Since then all I've done is secure the cable in place with zip ties etc, install the rear light via mudguard drilling, and now it isn't producing any light.

The connectors appear fine.

I don't own a multimeter or anything like that so can't check it.

I've probably pulled too tight and broken the wire haven't I? Hopefully the external wire not inside the headlight. Anything else it might be before I buy a new wire? Had hoped to get this up and running today

I'm an idiot. After fitting the rear light, I'd wired it the wrong way round. This apparently stops the front light functioning as well as the rear. Easy fix though!

Too early on a Sunday yeah?

I usually break at least one component, order the wrong size part, round off a critical bolt etc per bike build, so felt it was a safe assumption I'd snapped the wire

Happy to just be an idiot

I encountered a new to me problem where the front v-brake of my gfs bike suddenly bites to a full stop nomatter hard or soft the lever is squeezed.. does anyone know how to counter this? Would rather not have her eject over the bars if possible :-)

Broken spring, lip on the pads, misaligned wheel, bent noodle/lever/caliper, frayed/bent cable?

Probably check on some of those. Ill start with new cables and pads :-) thanks

Pads toed in?

Yes

I think the cable is toast and new pads wont hurt. I just couldnt see the correlation between the cable and this super eject bite.

I'd check that your chain checker isn't worn or not right in some way, meaning that you're changing your chain too early.

Wheel out of true?

Have you changed anything? Some levers have adjustable switches in them to change the pull ratio from v brake to road caliper, you might have accidentally toggled it

I imagine shifting would be pretty "vintage" in feel, but would work.

Cheers. I can deal with crunchy shifting and coming off power, just don’t want to have to be picking up a dirty chain from between the rings or wrapped around the crank arm every time.

Thank you

Its not the most perfectly aligned wheel out there but this has always been the case. Could be this in combination with something else.

Otherwise nothing has changed more then the fact that a winter passed and the bike was stored out with out cover.

The cable is squeaking and feels weird tho. So will get a new one asap.

Potentially n00b question.

I've got an old Giant TCR from on here and I'm refinishing it and popping some new parts on it to gift it to my partner once it's done.

I've got a new 105 groupset for a ridiculous £339 online and I'm blown away by this already.

Anyway...

I'm looking to buy hubs, bar ends, seat clamp etc from Hope for the sake of it all matching and looking and feeling like a new bike rather than the refurb project it is.

So I'm confident that I've measured accurately and it has one of these FSA headsets in it.

Can anyone point me in the direction of the correct HOPE Pick n Mix combination pieces to replace the current FSA headset? I've not got the insight to be able to confident Im buying the right thing(s).
Please and thank you.

If there isn't a suitable combo and I've misunderstood, sorry for wasting your time!

my memory said 51.

Do these chainrings look done? I've never been able to tell just by looking at them. The chain that came on it was done thought, 1% part of the wear gauge went right into it.

HSC7 and HSCC. It's just a 41mm bearing top and bottom.
