In my opinion the primary problem that various bike brands using the Bosch Smart System initially experienced was due to faulty batteries fitted in the LED Remote ( the bikes main controller). That battery is a rechargeable 3.7v lithium cell and is supposed to be charged by the main bike battery...
...which I assume means he can only bounce the bike on the back wheel which is not sending any shock through the front of the bike?
That said I would suspect mostly the headset nd since he has changed the bearings that just leaves the bearing seats or the starnut in the steerer tube which could...
when you rule out the obvious you have to consider the obscure!!
One golden rule for fault finding is to determine when it started and what occured ( a ride incident/maintenance/upgrades etc) immediately beforehand.
Some thoughts:
1. you replaced the headset bearings but are the bearing seats...
Umlikely to be a cassette or chain problem if both are new. When in the 2 biggest cogs the chainline is at its extreme and I think the chain is likely not sitting properly on a worn chainring.
vaccum packing?!! Thats a wet layup process to remove as much resin as possible.....................I would hope the majority of bike carbon composite frames are fabricated using pre preg and heated in an autoclave.
I have a 2020 E180 RS. Brakes are Code RSC and they are brilliant. I think the callipers are the same so a cheaper upgrade would be just to fit RSC levers.
I dont think it is any different to AXS is it? you fix the AXS mech to ( in this case) the UDH with the mech in its fully outboard position. Provided it is them teamed up with an Eagle cassette it know how to change from the highest ( smallest) gear to the lowest. The position of the mech in...
just thinking that the chainstays are invariably slightly wider than the hub so the correct torque would bring the chainstay carrying the mech to the same position each time.
Honestly there is some real rubbish being commented here!! First of all "carbon" is not an adequate description of a frame manufactured using a composite of carbon mat. It does not for example say that the composite is 100% carbon, neither does it say what modulus or carbon fibre mat type is...
I think you fail to understand exactly how the software controls the power delivery from the motor. The only performance parameters that most brands describe are the maximum NM the motor can deliver....e.g. 85nm for the Bosch performance CX, and "assist" as a % of the rider input.........in the...
Yep................cranks on both sides are standard thread.
The reason being that the crank is pushed onto a slight taper and held there by the 8mm bolt..........it is not threaded. The only thread involved is the bolt that pushes the crank onto the taper and crank rotation has not effect on...
well he says he is changing his sons cranks.......so I assume that means taking the existing ones off...........but he will also have to fir or refit pedals so all useful info.
yes the pedal thread on the crank is standard on the drive side and left handed on the non drive side............but he is asking a bout removing the cranks not the pedals.
.........or refer to the spec for your bike which will state the headset fitted....manufacturer and model.........e.g FSA No 57E 1.5. Look up that headset and you can see what bearings are used. The bearings already fitted ( what is left of them!) also have the bearing number and seat angles...
no...both standard thread.............either remove the 8 mm bolt and then use an extractor or just undo the 8 m bolt if they are the self extracting type.
If the only flip chip you have is on the shock linkage you have a high and a low setting.......referring mostly to the height of the BB. Fitting a smaller /27.5 wheel on the back would I think normally mean ensuring you use the high position. That flip chip also makes a small difference to the...
