That was another option I considered, but I'm trying to streamline the use of this bike. Hop on and go

Seth Brundle · 14-10-2022 10:09am

Would sir be interested in some oak?

😂😂😂

In general, how are these things attached? Do they just clip on (not the oak one, thank you very much)

hesker · 14-10-2022 10:35am

I’d expect they attach to the crank arm and you might need longer bolts and maybe spacers. Or they might require a purpose built chainring that has threaded holes for attachment.

I have a 2nd hand Pinnacle Arkose 3 (2015). One of those bright zesty green ones. It was both not used much, nor looked after brilliantly for the last few years. Components were all in good nick if a little scuffed. Anyway, swapped everything on it for an old Ultegra Hydraulic groupset I had earlier in the year (by I, LBS). I never bothered looking at headset though, and lately it's been a bit rickety.

OPened it up, and it was in a sorry, sorry state. Cleaned it out, could the cage open and cleaned the bearings individually. Lost one, had a spare. Regreased it all. Reassembled. Realised I made an arse of the handlebars going back on, went back and fixed and now it's much, much better. It's a short term fix for sure as they don't have much life left, but a very satisfying job.

Mundo7976 · 28-10-2022 6:30pm

My frankenstein is complete. Not the most pretty thing but functional & will work over the winter months. A bit twitchy up front, might be down to needing new bearings though. Pleased enough with the outcome.

28-10-2022 6:59pm

Are the new cranks a bit/much longer than the ones you took off? Hard to say for sure from the picture, how much space is there to the floor when the pedal is at 6'O clock?

Mundo7976 · 28-10-2022 7:16pm

Must be camera trickery, they're both the same length 🤷🏻‍♂️

CramCycle · 28-10-2022 7:36pm

Doing the same myself to a cheap planet X bike I picked up. Turns out the seat post is fused though and it's sitting a few inches to low. Planning to turn it upside down and feed ammonia through the bottle cage bolts

magicbastarder · 28-10-2022 8:23pm

aluminium frame? what's the seat post?

CramCycle · 28-10-2022 8:43pm

https://www.boards.ie/discussion/comment/119806042#Comment_119806042

Steel frame, aluminium seat post. I've tried freezing and heating but nothings budging. I might also use Cola instead of ammonia, would be more cost effective to try first.

Had the same issue with a Kona Paddywagon over the lockdown, went at it with hacksaw blades to try cut segments out etc, neighbour who’s a fabricator ended up just chopping the seat tube and welding a new piece in

magicbastarder · 28-10-2022 9:55pm

are you sure he wasn't lying to you?

Squidgy Black · 28-10-2022 11:18pm

Unfortunately yeah as I ended up having to paint it myself. Post had been in the frame for about 4 years and never moved in that time so was never coming out

edit: I have been whooshed

JMcL · 29-10-2022 11:08am

A bit twitchy up front, might be down to needing new bearings though

I think that's common with this style of frankenbike though. Hydrids trend to have longer top tubes and slacker head tube angles to complement the width of the flat bars. I imagine the latter is what's making it twitchy

Still, must say the result looks grand, and so long as the twitchiness is something you can get used to, what harm

beggars_bush · 29-10-2022 8:46pm

cleaned the bikes today. good deep clean too. nothing else to do as it was absolutely bucketing it down outside

cassette, rear mech, chains all looking very snazzy.

I've tried all the fads and generally they don't work or it's a combination of them all and then it releases and whichever was the last used i.e Coke its miraculous 😂

For seized posts I find the best is a soak in wd40 leave over night. Then leverage is your friend, lay the frame on it's side on a flat surface. Stillson spanner on the post and then a long bar on the stillson. 9/10 times it will break loose with the lightest or pressure. The seat post is generally a write off either way.

I have never tried the above with a carbon frame as they generally don't get stuck but I wouldn't recommend.

magicbastarder · 31-10-2022 11:38am

and AFAIK you don't want slow steady pressure to break the bond. you want a fairly percussive tap.

iwillhtfu · 31-10-2022 2:01pm

https://www.boards.ie/discussion/comment/119814847#Comment_119814847

From experience leverage has been the deciding factor on several stuck seat posts. Sure a tap on the seat tube may help similar to how an impact would work.

cletus · 31-10-2022 3:20pm

Agree with the above, if you can clamp the seat post in a bench vice, you can use the frame itself to increase the leverage

CramCycle · 31-10-2022 5:50pm

https://www.boards.ie/discussion/comment/119814640#Comment_119814640

Its definitely bonded alu to steel so Wd40 won't do anything unfortunately (I don't think).

https://www.boards.ie/discussion/comment/119815658#Comment_119815658

Already tried, not even a budge. It's so tight a blow from a hammer will just bend the seat post. My dad had a weird drop hammer thing that acts like a vice that will pull with a jolt but I'd have to make it as I won't be home for awhile. I'll try the coke first and then ring my dad to ask what it's called.

gameoverdude · 31-10-2022 5:59pm

Kinda off topic,but I actually used it!

Felt good.

https://www.boards.ie/discussion/comment/119806126#Comment_119806126

freezing it would have a better chance than heating it, as i understand, as Al has a bigger coefficient of expansion than steel.

Squidgy Black · 31-10-2022 6:17pm

https://www.boards.ie/discussion/comment/119816176#Comment_119816176

Probably a slide hammer is it?

cletus · 31-10-2022 7:03pm

@CramCycle at that rate I can't see a slide hammer working.

There are homemade jigs I've seen for pulling the seat post, but you'd want to have the materials to hand

Edited to add: if you can put it back in the vice, and get something to use as a lever (I used a length of 4x2).

Position the lever between the seat tube and the head tube, and use it to increase the torque as you turn

CantGetNoSleep · 31-10-2022 8:29pm

How often should you be removing the seat post to prevent this happening? I've had a bike fit on all of my bikes so don't like to fiddle with the saddle height

hesker · 31-10-2022 8:34pm

Sodium hydroxide solution has been used successfully I believe. Poured in the BB. It reacts with Al.

If you google it I think you should find an account of it. I would not have the frame completely upside down. Just a slight angle off it and add portionwise and rotate to add more

hesker · 31-10-2022 8:36pm

Also I think I read somewhere about a guy constructing a type of slide hammer again using the BB to add nuts to threaded rod or something like that.

https://www.boards.ie/discussion/comment/119816176#Comment_119816176

You just need more leverage. I'm talking get an 8ft piece of steel on the end of a stilson. I wouldn't use the frame to leverage as there's a good chance you'll bend something if it's that stuck.

The hammer you're referring to is a slide hammer they're used for pulling out dents in autobody shops.https://www.screwfix.ie/p/hilka-pro-craft-dent-puller-kit-9-piece-set/62730?gclid=CjwKCAjw5P2aBhAlEiwAAdY7dAoKww-x80QDOCZ11YGnPzuhkSvan5C-qfjQbv7-JtpNWYbG5qKJoxoC6NkQAvD_BwE&gclsrc=aw.ds
