Cane Creek Crank Preloader – Review

I have used it since summer 2018.

There is a huge difference is how smooth the Cane Creek collar spins vs the original preload collar from Race Face, making it easy to adjust the preload. the original Race Face collar with a tiny weak wood screw. But the Collar from Cane Creek was a big improvement, to the Robust Race Face Cranks, they served me well and took some abuse, but the collar and screw always annoyed me. So far I haven’t found anything negative about it.

The Titanium bolt bolt has also stayed secure for months, but I had to adjust the preload, it doesn’t loosen up fast like on the original Race Face preload collar, it can stay secure for months, so it’s more secure than the original preload collar.

The bolt has no signs of wear in months of use, which was not the case for the wood screw on original preload collar, which rounded off after fast.

The gold thread ring is not used for Race Face cranks, but for Sram cranks.

Hope Tech 36.4 mm Bolt seat post clamp – long-term review

The non drive side/ left side has an egg shaped threaded piece which the bolt threads into, this eliminates the possibility of ruining the clamp, via the bolt, as this part could be replaced, but I haven’t seen it sold desperately.

I bought these in august 2017, and used them since to now, 2019.

Cons:

  • The bolt has worn significantly, quite fast. I have two of these so I had to switch I did not want to round the bolt off, and end up with loose seat post.

  • the hex key does does not fit as tight as I wish it did, I have tried Park Tool Hex keys and Teng Tools bits which are even more precise than Park Tools Hex (Bondhus) keys. I noticed it was not good tolerances between the tool first when it the first use, with a park tool multi tool (Bondhus). I don’t know who makes the bolts.
  • Bolt can loosen up fast in big temp changes. Even with Loctite 243 the bolt has loosened up every time I took the bike out from the room temperature indoors to cold winter outside, few minutes and it was loose, so if you plan to ride with extreme temperature changes and ride hard it will eventually come loose and seat post will spin, this is also be common issue with seat rail clamps on many dropper post, or seat posts. Of course how fast it will depend on material combo and load, vibrations it gets, also had issue with loose bolts on Shimano brake levers clamps, and race face stems, but for secure stem Renthal Apex is has worked well for me, but for seat post clamps I don’t know which are the best, this was my first aftermarket seat post clamp.

I haven’t had any other issues with the clamp, the bolt turns smoothly

Pros:

  • the bolt turns smoothly
  • it fits precisely on the seat tube.
  • Lovely Laser etching
  • even surfaces, well made, no sharp edges, but it has a tiny texture to it, which also can bee seen, which some might like, you can clearly see it’s CNC machined.

Revised Review: 2010 trek 3900 disc


https://bicyclebluebook.blob.core.windows.net/zoom/trk_3900db_10_z.jpg

MSRP (new) $529.99

http://www.trekbikes.com/us/en/bikes/2010/archive/trek/3900disc/#/us/en/archive-model/details?url=us/en/bikes/2010/archive/trek/3900disc

this bike is made for commuting I have it in size 18,and in orange

the geometry so, not good for Mtb, for me, but for people with short armed and short back, this is not a bad thing, but I am about 180 cm high and i am average sized  everywhere,so  I get a very upright position, But when I was a teen i was not as big as I am now so it was ok.

which is too small of mountain biking  but for commuting its OK, you will sit upright.

the bike is no real mountain bike, frame is way too short and the handlebar is too short too, this make the bike too responsive.

ignore the sticker that say trek mountain bikes, it just refers to the standard for mountain bike frames. it’s not a mountain bike,but it can be with some upgrades.

Seat post parts look like this:

2010 Trek 3900 disc 18'' chain drop damage
2010 Trek 3900 disc 18'' Right dropout
2010 Trek 3900 disc 18'' - dropouts- upside down

the frame can withstand mountain biking, but the geometry is horrible for mountain biking.

cons:

  • max tyre size is 2.3
Chris King BB 30 & Race Face Turbine_0628
  • slack seat tube angle
  • steep head tube angle
  • horrible wheels, the rear wheel comes with a FH-M475 rear hub which has been troublesome, bending axle, possibly due to bad tolerances, this happen on all of the FH-M475 rear hubs I used.
  • The Shimano Acera M360rear dérailleur is horrible, too soft spring, no clutch. the use of a nut instead of a bolt was a bad choice.

  • The handle bar bends in a crash, a simple side fall will bend it.
  • Steel stem with only two bolts which is also quite heavy & low quality:

2010 Bontrager Approved 2 bolt stem

You can notice the low quality part I mentioned on the inside of the stem, weird wave pattern instead of a smooth hole, there were no wall there that has been rusted away, it is just made this badly, as you can see there is paint on it,so this means it clearly was like this when new.

  • The fork is a SR Suntour SF9 XCT V2, 100mm travel  does not have the promised 100mm travel, but more like 20mm, the fork had play and it got even more play so when i was braking hard i felt like the fork would snap or fall apart. it also lack of adjust ability.
  • Nylon Wellgo pedals, which were horrible, the plastic snapped on on side, I don’t remember how that happen, and they were very sketchy, foot coming off was a common issues for me. here is a review from Bikechanic for what seems to be the same or similar pedals:

  • The all in one unit Brake & Shifters/triggers: the stock are v brake lever and shifters, shifters are horrible you need to swing the lever way too far to change gear, so changing gear becomes unnecessarily difficult. if you want the shifter to be at a good angle the brake will be at a bad angle and wise versa.
  • Brakes: the bike comes with single piston mechanical brakes from Promax.. The mechanical brakes don’t work well you need to press very hard to brake. these brake are so bad that V-brakes actually are better for braking wise,not wear wise of course. so i upgraded  to hydraulic & shifters/triggers.
  • Saddle– saddle is way too big for me, it wears out fast because of flex in the saddle the plastic under  it that  have screws in it will flex too so the screws will pop out.
  • Overly beefy brake mount, it’s heavy, and wide.

  • horrible headset: VP-A68-TK, 1-1/8″ semi-cartridge, with horrible seal, making it a greasy rust water mess.

  • The Bontrager LT-3, 26×2.0 tyres got horrible grip in the wet they are a death trap. on wet asphalt they slip and you will crash, there is not enough space between the knobs and the rubber is too hard and not sticky enough to grab on to the asphalt check out the the review by Bikechanic :

winter ready & upgraded 2010 Trek 3900 Disc

Pros:

  • replaceable derailleur hanger, which is a must.
  • decent welds.
  • stiff enough frame for a average rider for at least this size.
  • the brake rotors can handle metal pads.

conclusion:

seatpost swap Trek 3900_1900
Most recent state of the bike, assembled with parts from part I took from other bikes I have, and some parts I had used previously. this bike does not fit me, but I just did this to have a spare bike, I will eventually build a new bike with some of the parts I have on the fuel ex plus some new parts.

waste of money, unless you need a bike fast and it’s the only bike you can then at the point you are i the store.

I only used the 3900 as winter bike, plus the front dérailleur does not work in  below -2 degrees for some reason, maybe due to the wear it has.

the review was originally posted 26 june 2015, but I improved the text and added pictures.

Lezyne Chain Drive chain breaker – Revised Review

Pros:

  • spoke nipple tool
  • smooth action
  • comes with a spare pin.
  • good ergonomics fits nicely and securely in my hands.

Cons:

  • Flawed handle design, the rubber ends pop off, you need them so the rod does not slide off, and be shoot off somewhere like out your window. to fix this, by replacing the the ends with Gorilla Tape or similar

Like so:
