DEORE Rear Hub FH-M6000 Review

DEORE Rear Hub FH-M6000 Review 


Another component added to be wheel rebuild. This is a solid offering, nothing fancy which I chose based on its pitch circle diameter. The bearing are smooth, the finish is excellent. The hub has mounting for centre lock disc brake, upon which I fitted a Shimano SM-RT30 Center-Lock Disc Rotor.



So if you need a rear hub with 9mm QR, and centre lock, which has a similar pitch circle to many older hubs you may which to replace then go ahead an buy this you will not be disappointed. This hub is a direct replacement for a FH-RM30.

Shimano Hub Dynamo DH3D32 Review

Shimano Hub Dynamo DH3D32 Review


This Shimano Hub Dynamo DH3D32 is the cheapest hub dynamo I could find that is suitable for disc brakes.  It is your typical Shimano offering i.e. perfect.  This is a 6 bolt version but there is also a centre lock version.


The  DH3D32 has the standard Shimano connector which is easy to install, although the stripped wires need to be just the right length.



The DH3D32 dynamo will illuminate the front light at a fast walking pace. It is advisable to buy a light with a stand light, this not only stays on whilst you are stopped, but smooths the flicker which nearly all dynohubs create when using a lamp without a standlight.

If you are currently using rim breaks why not buy this anyway, it will have a higher resale value, and allow for easy future upgrades.

Update: 2024 have just moved this on to another building, and is still going strong. Using it with a Busch and Muller Cyo 80 Lux. Perfect. 

Suntour NEX E25 - Review & Service

Suntour NEX E25 - Review & Service - Intro


 Suntour NEX E25 suspension forks are a suspension fork especially designed for use on e-bikes, presumably the 25kmh standard. I am not using these on an ebike. The forks are more heavily make to account perhaps for:

  • A heavier bike
  • a heavier rider
  • harder braking  
The forks have the following dimensions:

  • Tire Clearance - 54mm
  • Axle to Crown - 738mm
  • Stanchion size - 30mm 

Suntour NEX E25 - Updates

Update 2024. These have spent the last 3 years on a shelf, but recently I rebuilt them in to an ebike, and welded and extra length of steerer on to them to get up to about 400mm. I have also made so boots, to cover the exposed stations, and stop mud going on the silver bits. These boots used to be common pace on older forks but they got rid of them about 20 years ago because they don't look cool. 

Suntour NEX E25 - Review & Service - Use


The are suitable for "casual off road and paved road use".  I have used them off-road over very bumpy stuff, and I way 90kg / 15 stone.

I should note that prior to trying this fork, I was using the CR-8, a low end fork, even compared to this NEX E25 Fork which is worlds better.






These forks are slightly stiffer sprung, requiring less turns of the pre-load adjustment to make them good for riding. The lock out is a good feature.

Perhaps the most notable addition is damping, which stops the front of bike bouncing back up when you go over a hard bump.

I have ridden just 4 or 5 miles of off road on these forks, they do the job, thats all I can say.

The lock out is handy if you are stand up pedalling up a hill, but other then that I leave the forks unlocked.


Suntour NEX E25 - Review & Service - Guts


The specs from the suntour website give all manner of variations on these forks. In fact even afetr careful study I am not sure what model I have.

If you are not sure what you have best to head over the suntour website and look at the exploded views. Fairly sure this model below is what I have, but there are 4 other models some without lockout, and some with two coils.

Unlike the CR-8 this fork has damping which is a good feature to have! Even just for the 28" variants there are the follow models to wade through:

Suntour NEX E25 - Review & Service - Conclusion

In conclusion these are a great set of forks, which I purchased for £30 from discount bikes de,  their retail price is about £70 at which point you could probably find any number of forks to choose from, of a similar or better specification.

Suntour NEX E25 - Service & Strip Down

After about 6 months, and not much ride time the travel on these forks became much reduced. This was most annoying, and so I took them apart, dried the insides and greased them up. They worked like new when I put them back together. So that is good to know! I will talk you through process below. 


1 - First off  you need to remove brake caliper from fork. I also had to remove dynamo cable. This is so you can slide the leg (green bits in this picture) off of the stanchions (silver bits).


2 - Then undo the nuts on the bottoms of the fork legs. Both nuts. 


2.1 - These nuts come off like this  . . . . 


1.1 - We already mentioned taking the brake caliper off!


3 - Then you give the legs a good hard pull (perhaps stand on handle bars) and they will come off. 

4 - Use a rag and a pokey thing (stick) to dry out and remove old grease from inside legs, wipe off all old grease from stanchions. Then re-grease everything and reassemble. Engaging the lock out switch will make it easier to get the left hand (in this picture) nut back on. 

Works a treat. Happy tinkering!

Shimano SM-RT30 Center-Lock Disc Rotor Review

Shimano SM-RT30 Center-Lock Disc Rotor Review


I doubt many would bother to review such a humble piece of equipment as the SM-RT30 Center-Lock Disc Rotor , and I can hardly be bothered but here we are any way!

Update 2022: This rotor has lasted about 3 years. I am a heavy guy, and live in a hilly area. I probably use rear brake more than front. 

The SM-RT30 Center-Lock Disc Rotor is a disc rotor aimed at low end touring or beginners use, but inline with current engineering standards is over engineered to the point where it could be used by just about anyone for any purpose.

I have another low end shimano disc rotor I have been using for 4 years and it has been very good.


These discs I think are made by pressing or punching them from a sheet of steel alloy, as such these have a slightly rounded edge. If you buy a more expensive disc rotor they will have a machined surface. For the type of riding I do I notice no difference what so ever.





These discs are centre lock which means you will need to use the tool that you use to fit your cassette in order to screw in the locking ring, as illustrated below. The exception is when fitting these on to a hub with a nutted axle (Alfine for example) rather then a quick release axle, as most of these tools have a guide spindle that will get in the way when attaching to a nutted axle.

In conclusion I am happy (again) with my purchase and all is well. I would recommend these to anybody from old ladies to downhill racers.

Shimano MT200 Hydraulic Disc Brake Review & Install

Shimano MT200 Hydraulic Disc Brake - Intro


Search the for a set of hydraulic disk brakes, sort by price and at the top of the page you will likely see  the MT200 Hydraulic Disk Brake. They're very cheap especially if order direct from the far east. I paid £35 ($60) for my front and back set with rotors!

On the Shimano website these MT200 Hydraulic Disc Brakes are described as "Altus" which is a low end offering, but with Shimano reliability. I am steel using a 20 year old Shimano Altus chainset  on one of my bikes.

This is not my first set of budget Shimano disc brakes I have a number of  Shimano M355 Brakes which I have found very good. These MT200 Brakes and the M355 also take the same pads BS01, which is a major advantage in my book.

So I clicked buy, waited for about a week, and I will now share my findings. 

Shimano MT200 Hydraulic Disc Brake - Build Quality


Excellent when considering price. The moulding and the all sub-components are very neat and all edges are smooth and free from burs or any other machining defects.

The lever blade is made from a pressed steel, but this has been done is a way that results in a very comfy finger area (if that's a thing).


The brakes do not feel cheap or shoddy in any way they. Perhaps the one part that looks a bit odd is plastic cap that fits on to the inboard end of the lever housing. Bearing in mind the whole system has to contain considerable pressures, this large plastic section looks as though it could be considered a weakness, but I am quite happy to put my faith in the designers, I doubt it is a weakness it just looks like one.This plastic cap is fitted in SLX, Deore and XT brake levers so it must be well thought out.

Shimano MT200 Hydraulic Disc Brake -Fitting

Fitting is a cinch. You have to remove your grips etc. to slide this thing on the bars, but that no big deal. Use hair spray squirted under grips (prise up a little with thin screwdriver or small allen key) to loosen them up and then more hair spray inside when you put them back on.

The brake are pre-bled, so it is literally the case of just attaching them to the bike, and hey presto done! Fit and forget.



NOTE: When buying a set of MT200 be sure to get the right back and front lever combo. These brakes arrived with a Rear Right Hand / Front Left Hand suitable for the USA and most of Europe, whilst i wanted Front Right Hand/ Rear Left hand is is customary in the UK and Italy. 

I did think about buying a bleed kit, prior to swapping the hoses over. As it turns out I simply unbottled them swapped them around did them up with a spanner, and they worked perfectly without any further faffing. 


Shimano MT200 Hydraulic Disc Brake - Performance

Perfect. 

These MT200 brakes work as well as my M355 brakes other then that, I cannot comment. I have used by M355 brakes on a very large cargo bike, which can stop 200kg of bike, rider and children without issue.

 

Shimano MT200 Hydraulic Disc Brake - Features 


Below list is taken direct from sales literature:

  • Versatile design matches numerous bike styles
  • Less pad rattling noise
  • Braking power adjusted for entry level riders
  • Accessible lever reach designed for small hands - Note: Or big hands!
  • Easy, quick and clean installation
  • SHIMANO Hydraulic Disc Brake performance
  • Reliable braking performance with less noise

Shimano MT200 Hydraulic Disc Brake - Conclusions 

It is a perfectly good brake, and will no doubt give years of satisfactory service. The design follows features found in much higher priced models such as XT and SLX, and to be delivered even a sniff of that pedigree for £35 a set is fantastic.

CST Laser Trackball CST2545W-RC Review


CST Laser Track Ball CST2545W-RC Review

This CST Laser Track Ball Review CST2545W-RC is a heavily built large offering, which is made in the USA, it will set you back about £120 if you are buying this in the UK. It is probably worth it if you are having posture related issues, such as shoulder pain as it removes all requirements for you to push a mouse with tense shoulders all day.



The video above shows the trackball in use with me narrating on the task I am performing. There are some advantages, and some disadvantages.

Update 2022: After 3 years this piece of kit has been very good. I use it everyday, and even for stuff I would have switched back to a mouse for, I still use this. Having got quite used to it now. I did have a slight problem with it in that I used it one day with very sandy hands, and the sand got inside. I had to take it apart and clean out the interior. This was an easy task and needed doing any way. 

Pros - Comfort and "Throw and Catch"


The comfort is good. There is no need to tense you shoulder or upper arm. I found this aspect to provide more comfort from the outset.

When moving the pointer from one side of the desktop to the other you can throw and catch the ball. This is demonstrated in the above video.

Cons - Learning Period & Drag and Drop


It takes a while to learn how to manipulate your hand so as to achieve a drag and drop. You will be using all-sorts of muscles in you forearm that you may not be used to using, and this can take time to get used to.

I tried out "click lock" for a while to see if this would help but it didn't. The DPI setting I have also left of default.

Some Photos





 

Conclusions 


This is well worth the switch to improve comfort and posture, I would hesitate to make the switch if not required for practical reasons, not because it is not good to use a trackball but because you will burn up some time learning to use it.
