MGOOF : Modern groupset on old frame

That did cross my mind but thought it would be weird as I'd end up with some kind of GB/ITA frankenstein BB shell.

Although I suppose that's only a problem if I (or any future owners) are allergic to spacing a different bb if required.

It's very tempting as the cheap option though

Certainly no expert on sram and gxp but if they sell ita compatible bbs they surely must sell compatible cranksets to fit them?

Oh totally, it's way more likely that I've fucked up - I just can't work out where. The cranks are supposed to be compatible with BSA 68/73 which makes this even more confusing that they're nipping a 70mm shell.

I notice @noca has a GXP crankset on his Ciocc. Maybe he can tell me what I'm doing wrong? ;)

Yeah sounds fishy.. Are sram cranks really different for use with italian bbs than bsa bbs? Sounds unlikely as that would be a really bad solution from their part. U change the bb to make the crank fit the frame not a new crank because of different threads. But again i only use campy and shimano every now and then when im forced.

But thought the different axle length situation was a problem only with newer solutions for bottom brackets not regular threaded ita vs bsa.. its not with shimano or campy at least.

I have an Italian threaded Gxp bottom bracket in my Berra frame with a standard SRAM Rival chainset without any issues. So I don't think there are specific cranks for this..I assume you don't have any spacers installed?

Yeah that's correct - no spacers. I measured the shell just in case it was mysteriously oversized somehow and it looks like it's dead on 70mm. Full width of shell and bearing cups was about 94mm.

On a similar note, do you definitely have all the bearing covers for the GXP BB? I seem to remember there is a wavy washer too?

it's from local wheelset builder in my country. I believe he ordered it from Taiwan.

34mm deep, 21mm wide - internal width 16 or 17mm. so quite match with 25mm tires

I have those left over from another frame, though the wavy washer is only necessary for press-fit gxp.

Ah yes, right. Very mysterious!

i just want to confirm that there's only one style of gxp cranks

must be something else,

• either your cranks spindle is already much used
  
• or your sense for "nipping" the bearings is too sensitive, when the cranks only spin one
  round when tipping that's more than usual when the bearings are full of grease
  
• sram recommends putting more grease on the spline, sounds stupid i know, works frustratingly well, shows the inferior design of that spindle design (still got 10 bikes with gxp cranks on them right now ;))
  

Thanks for this! Yeah the cranks were basically just doing one rotation and stopping, and weren't spinning very freely by hand, with plenty of grease everywhere

They definitely don't have much wear, so hopefully it's more that I'm being oversensitive (or overtightening!?)

my guess is you're just oversensitive, better to call careful, which is a sign of love
can't really overtighten them 48Nm - 54Nm is recommended, 40Nm will still do the Job and is even a little more than most people would put on a square taper when trying to prove their toxic masculinity to give a relation if there's no torque wrench

I didn't have problems setting mine.
I had this sram red crankset GXP and I used it several years in a BSA frame. When I bought the Ciocc frame I didn't know it it was BSA or Italian thread. The seller did not tell me. When it arrived I noticed that it was italian (a friend of mine has a CIOCC for BSA bb)... I bought a Truvativ GXP for italian thread and it works just fine. No problems so far

Hello all,

Medium term lurker here registered to share my build. I got back into cycling during 2020 and soon started tarting up my old bike, which became bikes and led me here. Will make a longer post on my different builds in the right place, but here is the progress of my Merckx Strada OS so far.

I already had a Ridley carbon road bike and Kona steel tourer. This thread inspired me to buy a steel road bike with an interesting paint job, keep the quill stem and shift my Record 10 speed groupset from my 2018 Ridley to a more suitable home.

This is a secret bike/side sidepiece as my mate called it, delivered to work and all spannering has been on my lunchbreak - no shed space or tolerance at home for another bike!

Bike arrived almost a bingo card of anti:

Mismatched polished stem with black bars and post
Bizarre ball-trap seat
Gatorskins
Triple
Shifters/bar setup pointing to the Gods
Cages bent in so they wouldn't take 500ml bidons?!

However, all in good conditon, especially the chrome. Won it with a single ebay bid, shout to Kev from Margate for selling it and getting it shipped to Aberdeen fully built in a box. Also an unusual paintjob - googled and contacted Merckx and Snickers Workwear to see if anyone knew why the bike was painted in this livery but no joy! If anyone knows why it has been painted like this, please let me know!

Parted out the bits I didn't want, and kept the Mirage 9 speed mech and shifters and Calimas for my winter bike.

So far:
Complete 2008 Record groupset Inc. Cassette, chain and downtube lugs
Record headset - needed "persuasion" (read: big torque and slipping spanner) because I was impatient and didn't chase the fork threads. Always do this! Should've run the old headset back and forth to do it.
Cinelli Giro D'Italia bars
Selle Flite ebay bargain that I cleaned up
Kalloy post
Cheapo polished bottle cages
VDO computer
Wheels - carbon tubs with polished hubs and spokes from Arkane on the way

Everything came off and went on fine other than the headset! Still to cable it and get the chain on, nearly there.

Took a few goes to sort photos - now got an after and before!

Which one is the after? 😁

Few.

Nice, except for the Kalloy post

Kalloy makes solid, good looking posts.

They work great for a single built post and are fairly light, but I'm afraid they look like arse, and not to be a snob, but unless you're making a point, Kalloy probably doesn't belong on the same bike as Record kit...

Not sure if any alloy post has appreciable flex, but if they can, then the tall clamp design eats into flex length too

Cheers for the feedback all. @Ordinata deserved there, posting a half built bike in the wrong order! I will push on to get the bike finished and post a better photo... and work out how to embed in my post, in the right order!

Take your point @Kimmo, I struggle to get too excited about seatposts (as long as they match colour wise). Did consider a polished Campagnolo aero post but not really right for the era... Deda EL is about the only other?

There is a range of designs available from them, I was thinking about the 248, which in my opinion is a nice looking post.

Nitto is a good option as well.

Surely a Record post is called for. It's a Merckx
