Hi.

These crank bolts are M15 internal thread, 28mm cap diameter. Cheap on Aliexpress and huge colour choice.

Just went back again to mullet setup ?. I did'nt like the 29er front and rear. The bike was climbing better but in technical uphill the front felt nervous. Sometimes i even lost balance and was crashing twice. Cornering in uphill and of course also downhill was more difficult and the bike felt less plenty, less stable when descending. Had the feeling the front is not doing what i want but that i had to follow where my front wheel wanted to go ?. For me geometry with mullet setup looks way better and it also feels much better to me.

Anyone else tried 29er or 27,5 front and rear and would like to share his experiences?

I had a 29 inch dengfu e05. And I can copy your experience with the 29 inch tyres. My brother has a bmc amp with 29 inch and that feels completely different (better).

Lately I bought a second bike. The lightcarbon 004 with m600. It came with 27,5 tyres. What a difference! So much better and faster.

Today I tried a 29 inch front wheel for the lightcarbon Bike. And had much better Strava times after that. Could feel there seems to be more grip but it was more difficult to follow the corners. And had the front wheel almost wash out many many times. The point of losing grip is twitchy compared to 27,5 front wheel.

I question myself if the extra grip is worth the los of playfulness.

I’m going to switch the front wheel around a few times to learn what really suits me best.

Important to tel is that with 27,5 inch I use a 160mm fork. And with 29 inch a 130mm one. Geometry with 130mm and 29 inch front is same as 27,5mm with 150mm.

160mm fork with 29inch I tried for 100 meters and than turned back home because I could already tell I would not performed on the track as I prefer.

Your bike looks amazing. Thanks for the feedback. I prefer the mullet setup on mine which gives me increased confidence when climbing and smashing downhill. It seems we have the same fork/shock which works so well. Thinking of putting a mini water bottle under the shock - YT Thirstmaster 2000 475mL Water Bottle Set Black (For Decoy MY19-20)

Depends, I ride 27.5 fat 2.8 front and rear in the muddy slop of the English winter and as soon as the faster trails arrive in the spring, on goes a 29 x 2.6 Front.

Seems to work well.

How would you fix the bottle holder?

Did anyone buy these? (I did after drilling out the original one - which appeared to be made of cheese it was so soft). I'm not sure that they look a good fit on the stock cranks (and totally don't fit at all on the Luna X1 cranks - 24mm diameter required for those). On the stock cranks it looks like this:

The step down from the outer diameter to the inner is 1mm and the inner ring is 25mm. Seems to be a lot of pressure on the knurled thinner outer of the bolt to me.

For my shorter luna cranks, I was able to turn them down using a the ghetto method of a drill, a chopped up hex key and a file clamped to a work bench, it doesn't look the neatest job but gets the job done and requires very little skill ;-)

How do you fit these exactly….they look great.
Bore diameter 9.3 (not 9.5 als mentioned in installation drawing). Grease the rivet outside a little, push it into the bore (screw a M5 screw into the rivet and use a plastic hammer if needed, be careful). Thats it. When You mount Your accessory, be careful when You tighten the bolts. The screw pulls the brass insert upwards, compressing and expanding the rubber, fixing the rivet inside the hole. You dont get a clear feedback during tightening the screw, if You overtorque, You pull the brass insert out of the rubber, and thats it. It happened to me 2 or 3 times, not a big thing but You need to get used to the tightening force. The 9.3 mm hole looks quite big…

32T chainring ?! isn't that small ? especially for flat runs. I would expect you to climb trees with such gear..

The original chainring beeing 38T, I have mounted a 40T and I even have ordered a 42T : STRONGLIGHT E-Bike Plateau Bosch Gen1/3, Brose, noir | Bikester.fr because even on flat with the lowest the assistance I feel I have to move legs too fast... So I'm very surprised about 32T... but I would happy to hear your feelings about it !

I run with a 32/9speed 11-50. And it feels like a spin class but I do need to climb steep stuff so getting used to it.

Please can you detail with which items ? pics of your derailleur position ? necessary to use 12V derailleur ? i have tried with several ZTTO cassette (not find other in 11/50 9V), sram EX1 derailleur, sram X0 9V shift lever. It work corectly at workshop but the 2 taller pignos jump 1 teeth ofen when i apply strong torque to climb, alike if casette is worn out. i haven't find why ? in add i have broken several KMC 9 speed chains (bad quality, badly crimped). I ended by reinstall the 11 speed. But i will apreciate tio use 9 speed, it is enough for M600

So mullet setup is DEFINITLY the better choice then 29er front and rear. Bike again feels more playful, better in tecnical uphill and way more stable when descending. Just love it ??.
Thanks @thaeber for the hint with the correct wheel circumference ✌?

Thanks mate, my pleasure! Recently changed the front to a Fox 38 Factory 29“ 180. This fork really makes a difference, More speed, more confidence, very precise and forgiving on fast descends. Love it!

If I remember, you had a Mezzer Pro that I am wondering about, but now I doubt if it is a good option. I'm still thinking of Zeb ult 29 or lyrik ult 29. What are your experiences with mezzer?
