Trashed my dropper post(sort of) on my Orbea Rise. 2 plastic keyways in the post got muddled when I decided to take a rest a bit violently on the ground. Now my saddle flops to the right. Of course this is Orbea’s proprietary component(OC dropper) and I am at their mercy for a $6 plastic part which I ordered and still hasn’t shipped or rationalize spending $200 on a new dropper. Help me rationalize 🤔🤷‍♂️😂

The materials used for these guides are designed to be sacrificed from wear or a crash (you probably know this).

Brass pins or plastic shims are both good materials …but they are designed to fail during a crash or constant use to prevent any wear to the dropper shaft or tube.

I’ve rebuilt a few dropper's and recently rebuilt my nephew’s One-Up dropper. It was fairly easy once i acquired the brass pins from a LBS. His brass pins had completely disappeared into very small fragments

A thorough cleaning, re-grease and smooth operation got his (expensive) dropper back in business. I wouldn’t want to wait very long for these simple, cheap and necessary parts.

Could you make some? While you wait?

I bought a Shotgun seat for my daughter. She is obsessed. The only bad thing is now when I leave to go on a ride she gets sad if I dont take her.

Took the Hope rotors off my (analogue) Capra, stuck them on my Rise, ready for the Alps and Enduro2. As for what I’ve bought, well, prepping 2x Rise for the Alps and Enduro 2, I think I’ve emptied my bank account! 🤣

Thanks for the input. I did find the keyways that appear to be the same ( in pictures) from Jensonusa. Should arrive Monday. A friend has a 3D printer may give that a shot to fabricate them if the ones from Jesson don’t work. A bit disappointed in Orbea support to get the part out to me, particularly a part that should be in stock given as you pointed out they are designed to fail.

After a very wet and gritty ride the bike needed a bloody good clean, if only to stop it making that awful scraping noise! :eek:

# Once clean and dry, I lubed the stanchions on the suspension and also the chain and mech.
# I removed the callipers front and rear and cleaned up the whole area, including the pads and springs.
# I checked the pads front and rear, need new rears. One set ordered.
# I measured the disc thickness, front OK, rear 15% thinner than new, but OK. The rear is the one with the sensor on it, will take a look at the prices on those. Or can I make my own? Hmmm.
# I measured the chain and it needs replacing. The KMC X12 Silver that was on it (the only one I could get at the time) only gave me 707 miles. So I have ordered an XT instead, that should do considerably better.
# Cleaned my Shimano flat shoes (AM41), although they are still not dry after Saturday's ride. They don't make these anymore, so I need to look after them.
# The WTB Rocket saddle shoulders finally gave way after I had glued and stitched them together ages ago. I got another 1547 miles out of it which was more than the 1438 miles before the shoulder stitching first failed. I sorted through my parts bin and discovered a brand new WTB Rocket saddle that I must have ordered when the stitching first failed. My repair job wasn't supposed to last as long as it did. So that got fitted today. The old saddle is still soggy, so I have hung it up to dry and will inspect it for possible repair at a later time.

#The dropper remote or the cable is jammed and the dropper won't drop. I'll sort that out tomorrow.

I am ready for a beer after that lot. :)

Rebuilt my Orbea OC dropper
We have a what did you buy for your ebike thread, but I don't see a What did you do to your ebike thread

So here it is

Mods delete if not applicable
I rebuilt my 2023 Orbea Rise OC dropper seat post which was wobbling like a bad carnival ride. Ordered the so called proprietary part from Orbea on 6/12 they didn’t fulfill the order (charged my card on 6/12) until 6/18. Said it will take 7 days to deliver. Went to 3 shops for the trashed keyways everyone said oh you have to go to Orbea. Did some searching and found at least 3 manufacturers with similar looking keyways, ordered a set and like magic they fit. The seals are different but it was the keyways which are shredded. Repair was easy, no special tools. You can see in the pic next to the keyways strips of plastic. If I built another Orbea I would ditch as many as the proprietary parts as possible. Orbea should have quick turnaround on these sacrificial parts or at least give you an extra set on purchase of the bike. So order in advance of a problem, they will wear or break.

That looks like a good upgrade for those of us that like to take only the necessary tools with us. I had the Bontrager kit installed awhile ago but I must’ve over tighten the stem screw …it broke 😞. Trek store replaced it faster than I could say “Bad Carnival Ride”. I still have the replacement and original box hanging on the wall.

I also try to keep some spare sacrificial parts around …but when is enough-enough.

Bars, seats, peddles, pads, lotions, potions etc. Thank gawd I have a nephew and a few friends who just destroy bike-things.

In the early hours this morning I woke up thinking about how I measured my disc brake thickness (see post#100). I decided to check it today and I had made a mistake. :(

Both discs measured 1.96mm thick on the unworn area. The discs are engraved with "1.5mm minimum thickness". The front disc measured 1.68, so that's OK. But the rear measured 1.35mm, which is not OK. I ordered a new disc from Halfords today. Not only were they the cheapest that I could find delivered to the UK (inc P&P), at £69.82, but when I went to the site, they had a pop-up offer of another 10% off for cycling items above £30. So that became £62.84, click & collect from my local Halfords. (vs rrp of £84.99)

Here is a link in case anyone else needs a Shimano Steps RT-EM910 Ice Tech FREEZA Disc Rotor, 203mm. It's the one for the rear that has the magnet in it.

Put a new wheel on the Cube after a branch broke 3 spokes. The broken spokes punctured the rim tape and let the rim warp, so I put a tube in and cut the side knobs off because the tyre was rubbing on the frame. After I got back to the car I found the spoke spanner so I could have loosened the opposite spokes a little to reduce the warp - overall I learned a bit about trackside repairs and damaged a DT HX1501 wheel 🙁

Had another thought on riding with the warped wheel - I could have tried pushing the wheel to the side by ~5mm and tightened the axle - might have got back to the car without rubbing the frame and destroying the tyre.
The wheel is in at the LBS to get new spokes and hopefully the rim can be pulled back straight.

Nice bit of creative "get you home". :)

Was it your dog that introduced the branch into the spokes? :ROFLMAO:
She's too busy looking for snacks along the track - grass, wombat poo, lyrebirds :)
(just to be clear, she doesn't eat lyrebirds). She gets two or three 10 to 20 km runs per week on steep 4wd tracks and isn't allowed to venture off the track.

Installed a dropper on my new Orbea Urrun. I’m used to dropping motor on my Rail so no problems there. Headset cable routing means tight fit and bends through headset, head tube and into down tube, once everything strapped in the outer wasn’t going to move. I ended up with too much outer at the handlebars, and with the seattube end of the outer stuck six or so inches down the tube, there was no way to push the inner back through from the seat tube end after shortening the housing. Fortunately the dropper came with a barrel to attach to a bare cable end, so I was able feed the bare inner from the lever end, fit the barrel to the cable, fit the cable to the dropper, then pull the inner from the lever end as I pushed the post until the outer fit snug into the dropper.

Nice clean cockpit for the effort!

I decided to take my fox 38s to bits and clean them out and change the oil.
It took me quite a while as they are over complicated compared to my old RS pikes.
Only one picture of the air tube as I spent most of the time covered in oil 🤣

Salutary lesson on doing jobs right. I reassembled the shock & noticed the rebound knob was stiff. And the shock was slowly leaking air, so took it apart again & found the 10mm bolt that clamps the piston to the air shaft had rattled off. that bolt has a torque value of 4.5nm, essentially nothing but requires blue Loctite to hold it in place. I fogot the Loctite step & nearly borked the shock. Always rtfm folks!

Dropped the motor from my mates Cube stereo so that we could run his new magura MT7 brakes
was quite easy in all fairness just a certain way to do it
Add in the cables that all run through the headset as well as an added chore

But to change rear brake cable you need to drop the motor but only 6 bolts that secure it
2 hrs to disassemble and reassemble well happy just winging it
