Hi everyone,

I’m looking for some advice regarding an issue with my LCR018-D frame.

I recently took it on a longer ride (~150 km), and during the trip the storage door fell off several times. This is obviously quite dangerous, especially since I often ride in fast group rides.

Before the trip, I had already followed previous recommendations and tightened the bolt so that the lever is very hard to turn. Unfortunately, that didn’t solve the issue.

I then tried tightening the screw on the storage door even further, but the screw seems to be made of very soft material and ended up stripping/breaking. At this point, I can no longer adjust it, and the door is essentially unusable since it won’t stay in place.

My main question is:
Does anyone have suggestions on how to remove a stripped bolt in this situation? If I can get it out, I’m hoping to replace it with a higher-quality screw.

Bonus question:
Do you think the newer version of the storage lid is of higher quality, particularly with a better lever and a tighter, more secure fit?

Any tips or similar experiences would be greatly appreciated.

Thanks in advance!

Interesting you should post this.
Had mine out for a 3 hour ride yesterday, storage door fell off twice, second time it cracked my bottle and all my remaining water went flowing down the road. 2 hours with no drink!!!!

I don’t know what’s going on with the mechanism - I’ll need to take a closer look, but it definitely feels like a design flaw and not up to standard.
If the v2 is not a proper fix, then they either need to come up with a v3 asap or i actually feel like requesting a frame swap to a non storage version as it is simply not fit for purpose.

So annoying that one little feature can really ruin what is otherwise a crazy good bike.

POTOOOOOOOO

750ml Elite fly bottle for me.
It’s an endurance bike after all, so it needs to be able to handle at least this size if not bigger.
I know the roads are absolutely terrible, but the storage door needs to operate as well as a bottle cage just bolted to the frame.
I have a lot of big rides coming up in the summer and will need to sort this issue properly before then.

I use the same bottles in 750 and 1000. Hopefully the V2 door will be with me soon.
I got the shipping confirmation last week.

Fingers crossed it’s more secure

Definitely agree with you. I’m skeptical that a new version of the storage lid alone will fix the issue, it seems to be more an issue with the design of the locking mechanism itself rather than just the lid.

I’m really satisfied with the frame overall, but I do regret choosing the in-frame storage. Hopefully, LightCarbon will come up with a proper solution for this.

This is my only bike, and I ride it frequently - at least four times per week, including one ride of 200 km or more. I’ll also be using it extensively leading up to summer, when I’ll be participating in a 315 km race with our group doing at least a 36 km/h rolling average. On top of that, I plan to take the bike abroad for several trips, starting with Mallorca in two weeks.

Just to underline how important it is for me to be able to fully trust the bike during long, fast rides, especially in a group.

What size bottles are you guys using?

I’ve been using 750 ml bottles, and I’ll likely switch to 1-liter bottles soon. That said, the size doesn’t seem to matter - the lid was still coming off even when the bottle was in my jersey pocket and not in the cage.

While riding, I had to repeatedly pull the lid lever back up, and it would pop open again as soon as I forgot to do it.

If someone has the v2 storage lid, it would be great to hear how your experience has been.

Had a quick look this evening and it seems like the locking mechanisms tightness is dependent on the actual door being a tight fit in the first place.
My door has no foam on the very top edge.
I had put a bit of foam double sided tape up there not long after getting the bike and it made a massive difference to the locking mechanisms tightness.
This must have worn away, as on inspection tonight there’s none there, and the lock was very loose.
Just put another bit of foam tape on there, which makes the door quite hard to actually insert in the first place, but has tightened up the latch a heck of a lot.
It’s a bit of a bodge and not something I’m still 100% confident about relying on for big rides.
Will l contact Light Carbon to see what they say.

took another look at my storage lid and realized that I actually have the second version. I also confirmed that there is foam around the edges on the bottom of the lid. Before my first rides, I even added tape around the top edges as well.

At this point, I’m not sure what else to do. I’ve already sent a request to Jim, so I’ll wait to see what the next steps are.

For today’s ride, I plan to use electrical tape around both the bottom tube and the storage lid to try to keep it in place. However, this means the storage compartment itself won’t be usable due to the tape.

Hi Lads

I have the  V2 i never had the door fall off, but i do check before every run with the botle if it radles, the only time it did i tight the inside "lock" bolt.
One other thing is i have my bag full enought dat i can insert without being too mutch of effort and i dont slide it up on the tube, i just let the bag on the door to create a light "push" on the door. 

So in 10 hours of riding it, never had "ratles" sounds  or door jump off

Damn, I just ordered a frame with storage. My plan: only equipment to fix a puncture, so I will not open it regularly. I'll try to really fix it tight, with tape and foam I guess.

Finallyyyyy done.

Now time to give it some beans. Planning to use it for fast bunch rides, crits, gravel races, and more.

Very happy with the looks and quality of the frame. Let's hope the storage door holds up. Feels rigid now.

EDIT: first ride is in the books. Feels very fast, comfy, smooth. Probably partly due to the 40mm tires. Tires are rubbing when getting out of the saddle while putting some power down. It seems the LC statement of 38mm max is true.

I'll change the tires for road setup soon. Very interested to feel the bike with 28mm front and 30mm rear tire.

This is a size 54 with 80mm sadle height and 120/380mm bar from LC. I'm 183 with 89cm inseam. The bike feels quite short. Stack feels good but I wouldn't mind a slightly longer reach. An even longer stem would put the weight too much forward though. 

Size 56 with a non-rise cockpit would possibly fit me better. It's all within margin though and I expect I'll be able to get used to it.

Congratulations! Looks great.
How did you find the install of the big rock crank?

Im tempted by either the BigRock of Leese in 24mm (currently running 105), but dont want to mess about with a lot of spacers so that has made me cautious, all these new carbon cranks seem to have longer spindles than the standard Shimano ones - any feedback would be great!

Installing it was easy. I also have the 24mm spindle. Needed to use 2,5mm spacer on the DS to prevent the pm from rubbing against the frame. Added a 1mm on the left pedal to compensate it on that side. Pedals are now pretty much centered

Ah thats great to hear - thank you!

Finally received my size 56 frame in raw carbon  ;D.

Put it on the scale and not on the light side but not a big issue for me :
Frame size 56 with the front derailleur mount + storage door 1209g
Fork 424g
Handlebar 306g (90 length - 400 wide)
0 offset seatpost 193g

Big fan of the glossy raw carbon finish.

Started to mount it but I noticed that the rear axle doesn't screw freely as it should be : I mean I can't turn it easily by hand (for the front axle I don't have the issue).
I can for sure screw it with an allen key (but I can feel a little resistance).
When I remove the UDH hanger to screw the axle outside of the bike I can screw it by hand without problem.
I assume there should be a small misalignment between the holes in the frame (where the front axle goes) that may explain that.

Does somebody noticed this ?
Do you think this is an issue or nothing to be worried about ?
