They use BH59.  Both the olive and barb are brass colored.

Only the internal diameter is different. They use the same olive. Different barb. Use bh90 for a supposed slight performance increase.

Thanks for the replies all. Since I wanted tubeless and these are probably not that, I went ahead with tried and tested Panaracer GKs from a bike store that's closing down. I will eventually order the 40c and put them on a reserve rim set.

Yes 25c and 28c are both 350g/tire per the description. Never weighed my other road tires but that does seem heavy.

Out of topic since I could not find any shipping specific thread - what does "Shipping Partner: A C I" mean on USPS tracking. is that Ali-Ex shipping company? Parts worth $250 are stuck somewhere in California. The app every day shows 7 notifications saying there is an update on your combined package delivery and when I check the tracking page no updates at all. USPS says they are still waiting for that item to come into their possession. This is going on for past 16 days and I am losing it. It will be now more than 1.5 months since date of ordering. Curiously, other small parts ordered on same date have arrived 2 weeks ago. I noticed whenever AX combines multiple orders into one, this frustrating sluggishness happens.

Possibly a scam with falsified tracking, though perhaps it really has been lost. Raise a dispute asap. I had an order recently that tracked as arrived "in 3 days" but nothing actually had shipped. Ali even has a preselected reason of "shipping shows as delivered but nothing has been received". I'd put money on the seller proposing to give you a partial refund if you do. It's part of the grift. The item was around 30% cheaper that any other seller had it, and it had free shipping with DHL/USPS. I've seen a few similar listings since, the stores are usually fairly new with little to no feedback.

I don't trust anything that isn't shipped with standard ali shipping/Sinagpore post/Cainiao tracked etc anymore. 

How long does the battery last?

How did these work out for you?


Any new recommendations from anyone for center lock or 6 bolts rotors? Looking to get some for a new wheelset and replace the Deckas I have on there now

I didn't end up using them as i decided i wanted thicker rotors. They did make a good impression, looked to be well made and i'd buy them again. Measured as described at around 1.9mm thick.  If i was to order standard thickness rotors again they'd be my first choice at the moment. 

I installed these instead https://www.aliexpress.com/item/1005004913085313.html?spm=a2g0o.order_list.order_list_main.15.136018027PawHV

Have had one short ride and i don't think they're bedded in yet. They're absolute chonkers. Quite heavy. Measured with two callipers at around 2.17-2.2 which i was slightly annoyed by so i found another set and they measured at 2.3....

I read a review on the the Growtacs that said they have no modulation, and that all cable actuated brakes are the same. I wouldn't know having never used cable actuated disc brakes. Are hybrids the same?

I just ordered some disc brake hydraulic hose service parts. I need to cut down one of the lines on the IIIPRO E4 Mountain Bike Brakes I purchased a month ago.  Until now, I have never had to cut down the hose length of a hydraulic line.

I have that muqzi needle insertion device. It works well but is probably over kill given most people do that operation using those cheap plastic blocks either side of the line and tapping the barb in with a mallet.

The cable cutter is bullshit and is hard and finicky to get a straight cut with, which is annoying as you want a straight cut to sit flush against the end of the barb. If i bought tools for this again i'd look for a proper hydro hose cutter form park or at least the Chinese equivalent.

Also have the full ezmtb bleed kit, which has been good so far.

Anyone have a suggestion for IS and PM adapters? I bought some ztto branded versions but they're soft and heavy. Stripped the threads out of one today doing nothing more than would be reasonable when tightening a brake bolt.

Definitely!

Ah.. i read somewhere the 10 speed HG95 only comes with a pin. I got a refund anyway and will use the chain with while keeping a sharp eye on it and the rest of the drive train. Hopefully if it is fake it doesn't wreck anything.

Will be buying PYC chains from Ali for the next we while. They're about half the price of anything else local to me.
