Last week I damaged my Zipp 303 S carbon wheel from an impact during the Grizzly Peak gravel ride. I submitted a warranty claim, but it was denied for being "outside of intended use".

The 303 S is marketed for "off the pavement" and gravel use. Also, Zipp's Global Lifetime Warranty includes an example that is exactly what happened—damage from a pothole/sharp rock impact while riding is covered. The claim was rejected without any further detail beyond the generic "intended use" denial.

Since the manufacturer only works through dealers, I'm stuck.

Has anyone successfully fought back against a Zipp warranty denial when the damage clearly aligns with their own explicit examples of coverage? Any advice on how to push this to be covered would be greatly appreciated.

52/37 on SRAM red AXS

I’m running a SRAM Red AXS setup with a 52/39 and 10-33 cassette, and I really like the 52 for high-speed riding (especially descents). The only issue is that the 39 feels just a bit too hard on longer climbs. I’m considering swapping the inner ring to a 37 (so 52/37), even though it’s not an official SRAM combo. The goal is to keep the top-end speed while making climbing slightly easier. Has anyone tried a non-standard combo like this on AXS?
How’s the front shifting performance and reliability compared to the stock setups? Worth trying, or better to stick to SRAM-approved pairings?

SRAM Rival Chainring Cracks

Just noticed several cracks in the front chainring (SRAM Rival 48t). Got the bike Jan, 2025. Not sure how long it’s been this way.

Hopefully just cosmetic but has anyone experience this before? Is it toast?

Where to actually BUY Sram components in the US?

Hi All!

I have finally settled on wanting to use 1x13 Rival AXS for my new gravel build, but I am struggling to find the best retailer to actually buy the groupset at. Does anyone have a recommendation for a reputable online retailer?

edit: I should have put this in my original message. I LOVE MY LBS and I use them a lot! I am attempting to project build a bike for myself and I am sure I will end up there eventually when I fail. Thank you all for the feedback!!!! I will chat with them and see if they can help me source the parts. I felt like a dick asking them to just help me buy parts so I could try and put it together myself.

12 speed cassette and chains longevity

My chain started skipping in the three most used gears on my last ride. I've just checked one of the three chains I rotate and it measures ~12⅛ inches over 24 pins so around 1% worn.

The good news is the cassette lasted an amazing 17,214km, with a shade under 6000km on each chain!

Is my shifter good for trash?

After 10000+km my sram force 11 spd HRD shifter had some issues shifting down, took apart to see what’s happening,
Can I fix it ? Should I change the derailleur cable ?

When I need food or drinks during my rides, the Karoo has the route, but to find something that's actually open right now i was always checking out my phone. That is kind of annoying because when biking to the place I needed to have my phone out.

So I ended up writing a karoo-ext extension that solves this for me. it adds nine data tiles to the ride profile page — restaurant, supermarket, cafe, hotel, doctor, pharmacy, bike shop, ATM. Each tile shows the nearest POI in that category with distance + name + the opening_hours. A tap on the tile and the karoo's pin activity opens so you can route to it or save it.

I only tested on karoo 3 so far. If anyone tries it on karoo 2 i'd genuinely love to know whether it works.

I would love to hear your opinion, bug reports or "this would be useful if it also did X"

1 Mullet, 2 wheels

I’m building a new Mog frame up and am going to be using it for road training and gravel racing. I’m trying to decide between XPLR and Eagle transmission - I live in the mtns where 10% percent grades are common so the 52 cassette might be nice, but when on road it would be helpful to have tighter gearing at the high end.

I’m thinking of using an XX rear derailleur and Force E1 shifters. So my question is, would it be possible to run a road wheelset with a 13sp XPLR 10-46 cassette and a gravel wheelset with 12sp 10-52 cassette?

Crankset width would need to be wide in either case, correct?

Thanks!

Hi!

I am going to get a new bike with the following gearset:

  • Groupset: SRAM Force AXS
  • Crankset: SRAM Force w/ Spindle Powermeter 48-35
  • Cassette: 10-33

I would like to buy a pre-waxed chain so I can ride the bike right away. I am struggling to find the right one (needs to ship to Germany).

How do I know how many elements I need?

I think I need the flattop one, so does this mean the 3rd is the only one that would work?

New to chains, so thanks for your help!

Here are a couple I found:

After seeing a couple of threads about the difference between the Force and Red versions of the new threaded power meter spider, I decided to make the definitive guide to the different versions.

One thing is common between all of them: they all measure the same, meaning a thread chainring will fit all of them (obviously road and mountain bike versions have different offsets, but that'a another topic for conversation) and any 8 bolt crank will fit them.

  • Photo 1 & 2: Force and Red versions. They operate the exactly same way, the only difference is down to the battery cover design, which in the Force version is meant to integrate better with the redesigned Force cranks. Also, the Red version is more expensive, but that's SRAM being cheeky as they have the same model ID (PM-AXS-SPDR-E1).
  • Photo 3: XX SL version. It's basically a striped down version of the road ones with no battery cover other than the metal one. Same thread and 8 bolt mounting points.
  • Photo 4: 1987 Collection. It's a Force spider, but with silver features to match the rest of the groupset. Given that it's compatible with Flight Attendant, it makes me think that the Force and Red ones are also compatible, but I haven't been able to confirm that yet.

In terms of chainring availability, you can get road/gravel 1x from the Red XPLR line, you can get a road 2x from the Force E1 line, and 1x mountain bike versions from the XX SL line.

For aftermarket 1x rings, I'd recommend Garbaruk, for both road and mounting bike ones, and the nice thing is that they're all compatible with road flattop, Eagle and T-type chains.

Let me know if you have any questions or if I missed anything. Cheerio!

Can someone help me with my decision to go 1-by with my Rival set?

https://preview.redd.it/zg70enhd0yzg1.png?width=994&format=png&auto=webp&s=36a0b12b9f385f5614fccae89a243ce7d27381e6

Above is the group I currently run. My front chainrings are 48-35T.

I want to switch to a SRAM Aero 1-by chainring with either 48 or 50T.

I'm just totally lost to which are compatible and what I should be looking at..

Would I also need to switch out my cassette?

As for why: I have ridden 1400km on this bike and I just have NO use for the smaller chainring, I live in what should be the flattest country on earth where climbing is nonexistent. I have 120km rides here where elevation rarely is more than 200 meters. It saves me maintenance and a whole front derailleur headache.

Transmission noisy in lowest gears

I just got an Epic 8 EVO with GX Transmission. The next to last low gear and a bit of the lowest gear are noisy. All the rest of the gear combinations are quiet. I got the bike new and on the first ride I noticed the noise so I jumped off to check if there was something obviously wrong but I could see nothing. I then tried to reinstall everything and make micro adjustments (I did all this about 3 times) and things did not get better. I took the bike to the shop and it was adjusted again but that noise is still there in those low gears. Is this normal for this setup? Will it get quieter as the miles accumulate? Or should I try something else? It is not a horrible noise but it is definitely there. Especially in the middle of a steep quiet trail.

SRAM FORCE E1 2x set up. Trying to add two wireless blips. No matter the sequence once the Blips are added something gets kicked off/out. Either I lose the both front levers or I lose the FD after pairing both blips. I have followed SRAMS viddys and GPLAMA's for adding blips to an existing system. I am sure it is something simple, but have not found the solution yet.

Thoughts?

Hey everyone,

I’ve been struggling with this issue for a while now and can’t find a fix. Hope someone here has experienced the same.

Setup:
• Quarq SRAM Force Powermeter (brand new)
• Wahoo Elemnt Bolt v2

Problem:
The powermeter is paired via ANT+ on the Bolt v2, shows full signal strength and status “Connected”. Cadence (RPM) is transmitted correctly. But power output is stuck at 0W the entire time, no matter how hard I pedal.
What I’ve already tried:
• Removed and re-paired the sensor on the Bolt v2
• Zero-Offset calibration directly on the Bolt v2 → works without issues
• Fully closed the SRAM AXS App to rule out a double connection via Bluetooth
• Restarted both the powermeter and the Bolt v2 multiple times
• Tested the powermeter with the SRAM AXS App → power values are displayed perfectly there

So the powermeter itself seems to be working fine. The issue is specifically with the Wahoo Bolt v2 not receiving/displaying the power data over ANT+, even though cadence comes through without problems.

Has anyone seen this before? Any ideas what could cause the torque signal to not come through over ANT+ while cadence does? Could it be a pairing profile issue?

Thanks in advance!

Hey all, trying to sanity check a mixed drivetrain setup and would appreciate some real-world input.

Current setup (Lauf Seigla Core Transmission):

  • SRAM S1000 Eagle Transmission derailleur AXS wireless (stock on Lauf Seigla Core Transmission equal to GX Eagle AXS)
  • SRAM XS-1299 Eagle Transmission cassette (10–52T)
  • SRAM T-Type chain
  • DT Swiss 350 hub with XDR driver

Planned change:

  • SRAM Rival X-Sync 42T chainring (8-bolt, 6.5 mm offset, road/gravel)

From what I understand:

  • T-Type chains can run on SRAM AXS road/XPLR chainrings
  • But those chainrings aren’t Transmission-specific, flattop vs T Type I think!

So my questions:

  1. Has anyone run a setup like this (Transmission cassette + T-Type chain + XPLR/road chainring)?
  2. Any issues with chain retention, noise, or wear over time?
  3. Is there a noticeable downside vs using a proper T-Type chainring?

Not worried about “official compatibility” as much as real-world performance.

Appreciate any experience or insight

Hello!

I’m currently building up a gravel bike and I’m going for a 2x system. I’ve already bought a crankset (Force WIDE 43/30). The frame I’m going for will require a clamp-on front derailleur hangar. I am able to get hold of a normal Force FD for a very good price, whereas the wide derailleur would likely be at retail price. Here’s where the question actually starts… Does anyone know if it’s possible/advised to get a FD hangar that would mean I could just use a normal FD for this set up? Or am I missing something about the wide derailleurs?

Any tips or tricks would be really appreciated! Thanks!
