Hello all, I'm having some challenges with a new GXP BB. I've installed many over the years (threaded and pf), and have never had any problems with them, despite the internet seeming to think they are the worst design ever dreamt up.
I'm now trying to install a threaded GXP BB, but on an Italian BB shell. I've ordered a SRAM ita BB and expected the cups to be a couple of mm narrower to make up for the 70mm shell width. However, when I compare to a bsa BB, the shells are exactly the same width.
I did the comparison, as when I tighten up the crank bolts even lightly, the crank rotation is very stiff. Upon inspection, it appears that the NDS splines perhaps don't stick out enough? I suppose this makes sense if the shells are the same width as bsa, as the axle should perfectly fit without spacers when the shell is 68mm?
Have I been sent a dud BB? The threads were fine, so it can't be a bsa one. Is there such a thing as a MTB-specific ita GXP BB that would reduce the need for spacers? I'm quite confused!

thanks.
shakedown ride planned for tomorrow morning which will be a mix of road and offroad around the lanes and bridleways of leicestershire, before a bigger ride up to a YHA in the peaks towards the end of the month.
This is relevant to my interests for when visiting family. I've really struggled to find much good stuff in Leicestershire, particularly further south around Hinckley/Lutterworth/Earl Shilton kind of area.
I was actually looking at doing a ride towards Shackerstone (went to school in Market Bosworth so interested to go back). Looks like there's more options around there. Love that you went through Barton in the Beans. Always thought it was a wonderful name for a village.
Edit: sorry, was @MTB-Idle who did BITHB!

I think you can still get hold of the 11sp Red etap derailleurs, but they will cost a fortune. You could buy a 2nd hand one that may or may not break immediately, or a new one for £500+. I think the problem with that investment is that you will be struggling to get replacements if other components break (I think they are only still selling the derailleurs new).
I think you can probably buy some previous generation 12sp AXS rim brake Force/Red shifters new still that you could pair up with 12sp derailleurs - probably the cheapest and most future proof option?
It's a pain tbh - I wanted to put wireless onto one of my rim brake bikes, but didn't fancy the cost/risk of 11sp etap.

Have no knowledge of these at all, but seems kind of cool for £79 and comes with all original paperwork: https://www.ebay.co.uk/itm/156381599155?

7 years later and I'm finally getting round to building this.
Managed to get a basically new Force 22 mini groupset for a steal and have ordered matching cranks to go with it. Not at all period correct, but should be fun to ride!
The rest of the bits were on the spares cupboard/lying around. No idea what the bars are as graphics were removed - think perhaps Deda or maybe Ultimate Use. Current plan is:
- Change headset to a black one - need to transplant Cane Creek from old frameset
- Deda Superleggero stem (previous owner cut steerer very short so need low stack)
- Have some Praxis chainring to go on the Force 22 cranks
- Maybe consider shallower wheelset, but that will have to come later...
- Change headset to a black one - need to transplant Cane Creek from old frameset

Hi @Velocio - please let me know if this is not allowed. Couldn't see anything in the rules (but there are a few so may have missed).
A few years ago, my septuagenarian father in law retired and soon after purchased a bike, which turned out to be a fantastic investment. An estimated 20,000km later, it is clear that he has benefited significantly from the many health and wellness benefits that we are all aware of as members of a cycling forum.
In 2022, he completed a cycling challenge where he raised money for the Alzheimer's Society. He is currently completing a similar challenge throughout August, but this time with much more personal meaning, as he was diagnosed with Alzheimer's in autumn of last year. The original goal was to complete 100 miles in August, but he has smashed through that, and it looks like he will complete over 300 miles during this period, which is hugely impressive all things considered.
I suspect that many members of this forum are of an age where we are starting to be affected by dementia, primarily through our parents. The Alzheimer’s Society is working towards a world where dementia no longer devastates lives, and I would appreciate any support for my father in law as he tries to raise money for this worthy cause. At the same time, I understand that times are tight, so if you are unable to donate, some Strava Kudoses (Kudi?!) would be greatly appreciated!
The link to donate can be found here: https://www.justgiving.com/page/simon-armson-1722535754265
Thanks.

I think that really short rocky field side bridleway in the first pic gets everyone by surprise on their first trip round the new forest
Ha, gold star! I've been on a few trips there, but first time on that section. Very tight and plenty of stinging nettles. No way you're getting a horse down there! Was great fun tbf, and a highlight of a pretty mega day.

Rubbish. He loves racing a bike, irrespective of the discipline.
But the money is in road racing and he's only really dabbled in it so far, he needs to commit for the next couple of years to see where his ceiling is.
But a Grand Tour isn't just 'racing a bike' is it. Have to deal with travel, media, politics, essentially living with the same people for a month etc etc. It's a hassle. Also, much of the riding is boring compared to bombing around an XC course. Not every day is the Galibier descent.
And as for 'dabbled', he's done 4 GTs lol.

Already did this before ordering the BB. It is exactly 70mm. There are no spacers in play at all.
I have double checked the cups and they both say ITA on. I just don't understand why they are the same width as the ones used on a 68mm shell that doesn't need spacers. Clearly going to lose 2mm somewhere on the axle?
Have tried to find standard cup widths, but SRAM appear to want to keep their secrets.
