Narrowed it down to 3.....

[Ks45672]

i  am buying a basic mtb for commute  and some semi rough recreation

 

Owned great bikes in the past from Giant, Cannondale ,Scott etc and i know you get the quality/longevity you  pay for but dont want to spend  much  as this will be locked

outside  a lot and need to replace immediately  if  stolen etc without much tears ... 

 

which of these 3 would you take (basicaly all the same price and similar spec )

SPECIFICATIONS

27.5 inches
Frame, handlebar and stem
14.45 kg in M w/ pedals
S/M/L/XL

COMPOSITION

Frame : 100.0% Aluminium 6061

PRODUCT TESTS

We also recommend that beginners wear cycling shorts with a protective pad and/or a gel saddle cover to reduce soreness.

THE STORY OF THE ROCKRIDER 520 MOUNTAIN BIKE...

Entirely designed and developed in France at the B'Twin Village (Lille), this mountain bike is the fruit of the work of an expert team of passionate mountain bikers. The Rockrider team designed and tested the Rockrider 520 mountain bike with their test riders.

A UNISEX MOUNTAIN BIKE

Men's or women's mountain bike? 
The Rockrider 520 mountain bike is unisex.

For greater comfort, the women on our mountain bike team recommend replacing the saddle with the Women's 500 Sport saddle, which is adapted to women's bodies.

HOW DO I CHOOSE MY MTB SIZE?

Several sizes available: 
S: between 1.50m and 1.64m
M: between 1.65m and 1.74m
L: between 1.75m and 1.84m
XL: between 1.85 m and 2.00 m

If you are on the limit between 2 sizes: 
Choose the smaller size for easier steering (easier to handle) and comfort (straighter back).
Choose the larger size for easier pedalling with a more stretched-out position (position more suited to performance).

A FRAME THAT COMBINES THE JOY OF THE RIDE & THE PLEASURE OF STEERING

For a lighter weight and more efficient pedalling, the Rockrider 520 frame has been designed with 6061 aluminium (only 1.9 kg in size M). The lower bottom bracket helps keep you more stable during turns.

FRONT SUSPENSION TO CUSHION UNPREDICTABLE TERRAIN

Calmly face new obstacles (roots, pebbles, stones, etc.) with the front fork with 80 mm of travel. 
Easy: use the wheel to adjust the stiffness of the fork based on your weight.

REAR SUSPENSION: NONE

This mountain bike has no rear suspension. This is a "semi-rigid" mountain bike.
Compared to a full suspension mountain bike (with rear suspension), the advantages are clear: lighter weight, you will spend less energy on flat ground. However, if you want more comfort, the RR 520 also exists in a "full suspension" version with a rear shock absorber.

DERAILLEUR & DRIVE TRAIN: REACH GREAT SPEEDS

3 8-speed chainwheels, or a wide range of 24 speeds.
2 quick shifters on the handlebar.
Left (chainrings): control ascents/descents.
Right (speeds): more precise control over your pedalling.

In detail: 
- Triple chainwheels - 22, 32 and 42 teeth
- MICROSHIFT MS22 front derailleur
- SRAM X3 rear derailleur
- SRAM X4 shifters, with speed indicators
- SRAM PG820 8 cog cassette, 11 to 32 teeth

HANDLEBAR, STEM, GRIPS: TAKE CONTROL OF THE HANDLEBARS

With its adjustable stem, the RR 520 controls are close at hand. The all-aluminium B'Twin stem is 70 mm (size S), 80 mm (size M/L), or 90 mm (size XL) and can be raised using 5 adjustment intervals: + 0 mm, + 7.5 mm, + 15 mm, + 22.5 mm, + 30 mm.

In detail: 
- Aluminium "oversize" handlebars are 660 mm (size S and M) or 680 mm (for L and XL) wide
- B'TWIN SPORT "soft touch" grips for a good grip and comfortable feel in your hands.

SADDLE / SEAT POST: COMFORTABLE AND SPORTY SEAT

Since your mountain bike rides will get longer and longer, it is important to have a suitable seat. So our teams have designed the exclusive B'Twin Ergofit Evo saddle. Suitable for all hip sizes, its "hammock" shape is particularly noticeable during sport touring. Along with the 27.2 mm diameter aluminium FLEX seat post, it guarantees greater comfort.

Easily adjust the seat height using the quick release on the seat clamp.

DOUBLE DISC BRAKES: GET A GRIP ON YOUR BRAKING

No matter what conditions you ride in (dry/wet/mud), the HAYES MX5 front and rear mechanical disc brake calipers offer powerful, progressive braking.
The TEKTRO aluminium brake levers are easy to grip, lightweight, and precise.

DOUBLE-WALLED 27.5" WHEELS

Have fun with the 27.5" double-walled aluminium Aero Trail Evo wheels. Their diameter is the perfect balance between comfort and performance. With their 28 spokes, they are lightweight, stiff, and durable.

DOUBLE-WALLED 27.5" WHEELS

Have fun with the 27.5" double-walled aluminium Aero Trail Evo wheels. Their diameter is the perfect balance between comfort and performance. With their 28 spokes, they are lightweight, stiff, and durable.

TYRES FOR DRY TERRAIN

The exclusive 27.5" x 2.0 B'TWIN ALL TERRAIN DRY tyres are adapted to dry ground. Their side lugs provide good traction during turns. The central tread provides good performance and the side lugs offer traction during turns. 
Recommendations for pressure based on the cyclist's weight are marked on the sidewalls.

PLATFORM PEDALS

The RR 520 comes with MTB bearing-mounted platform pedals made of hard resin for light weight and safety. 
If your foot slips off the pedal, there's less risk of injury.

EASILY TRANSPORT AND STORE YOUR MOUNTAIN BIKE

Cycle touring does not start from home; that's why we have made it easier to remove and replace the front and rear wheels. They are equipped with a quick-release system.

WEIGHT

14.35 kg in S without pedals.
14.45 kg in M without pedals.
14.55 kg in L without pedals.

My experience of  "TrinX' is to avoid them at all costs

 

There seems to be a glut of them for sale in the  Pattaya Auctions and on Facebook selling sites from as little as 3000 Baht to scammers looking for mugs at 12000 Baht.

 

Giant, Haro Merida all do  entry level low priced  Mountain bikes or Hybrids and if you look for some promotions especially of last or the years models or earlier you can find fantastic deals and have something you can sell when you are finished with.

 

I bought a last years model of a  Giant 2 escape from Khon kaen bikes  mail order at half the  original price , my friend Bobbo bought a  brand new  older model  (2 Years) Cannondale a t 45% of the original price 

 

Just a few thought for you but please avoid "Trinx"!

[StreetCowboy]

I've got Shimano Altus gears on my hybrid, and I'm quite pleased with them (you'll see a few posts about that bike recently on this forum).

 

I would recommend hydraulic disc brakes in preference to cable-pull mechanical disc brakes, based on my experience (much better feel) although that could partly be flat handlebar versus drop handlebar ergonomics as well.  On the other hand, hydraulic brakes are beyond my own technological capability to maintain, although apparently not difficult.

 

I would go for 29" rather than 26" wheels; 9 gears versus 8 won't make a significant difference.  The gearing range is similar.  You'll go slightly further for each turn of the pedals on the 29" wheels, but with a lowest gear ratio of almost 2:3 you'll have more traction than you can control at the lowest gear on any of those bikes.

 

Personally, since I do all my riding on the road,  I would try to find a bike without any suspension; its just added weight and energy absorption, and at that price, something else to go wrong.

 

 

The security guards in my condo are riding new Trinx bikes now - I think there are two been bought by the management company, and one of the barmen in the pub across the road rides a Trinx, and it gets him to the pub every night.

i do understand that "cheap " bikes are a false economy if something will break every week the repair costs will mount up fast

but i examined a few of the better equipped  trinx bikes in  the store on rama 9 and they are a step above  the crap that sells in supermarkets like  walmart. tesco or big C  etc 

 

Also visited and called a few bike shops around town and also checked  the 2nd hand ads  but most  2017 discounted are only in size S or M

and i need one with a 19" frame because im tall

 

I think theft is way   more likely than wearing out components through high milage etc as i may  need to leave it locked outside offices / bts /mrt /carparks  from morning until late night 

and if its gone its gone as they say ........

They are not as badly built as most chinese crap ,maybe the 3k ones are 

but the 8-10k ones feel pretty well made  

it is hard to find a mountain bike these days without a cheap useless suspension fork on it 

but the trinx x1 only weighs 12kilos and you can lock the suspension so it doesnt move at all 

 

i also prefered the 29" inch wheels but its  currently out of stock so that makes the choice a lot  easier :)

 

 

[bobfish]

I'd probably go second hand to get better quality [smoother and rebuildable] components with spares back up. The average thief won't know the difference and would probably opt for the shiny Trinx anyway. 

 

I wouldn't get too carried away by wheel size - 29 or 27.5 would be nice - but I wouldn't discount a nice 26. Still plenty of mid range tyres/rims around and ride fine for the intended use.

thats the problem if your taller than 6 foot

the 2nd hand bikes in that size are few and far between 

 

most theives wouldnt know the differnce between shimano  altus or xtr so both could  still get stolen 

but you will not  be bikeless for long when you  can  replace the trinx next day for 8k

 

 

[ttakata]

I'd get the q800 for the 29" tires.  Bigger tires are always easier to roll over the crappy roads.  I have a cheap 4" fatbike and riding is so much easier since I don't need to avoid storm drains and potholes.  Sadly a fatbike with sealed bearing hubs is pricier at around 14k and up.  If theft is the concern I'd buy an even cheaper bike. 

 

Bike show at Impact Arena coming up in May.  You can check out most of these no name brands there.  http://www.internationalbangkokbike.com  Usually some really good deals there.  This site carries most of the cheaper brands http://888bike.net/category/6/จักรยานเสือภูเขา

A fair point. I'd be interested in how the Trinx handles the 'semi rough'. Seems like an argument for n+1: One beater pub bike and a proper MTB.

Somebody on another thread in this forum took a wire brush and a spray can to his bike to deter thieves.

Just padlock your bike to another bike that is worth more...

[StreetCowboy]

The first bike that I bought here was a Mondraker mountain bike that was the closest fit that they had in the shop, and I think old stock they were trying to clear.  Despite being too small, it was a great bike, and I attribute that to my current enthusiasm for cycling. 

 

If you buy a good bike, you'll enjoy cycling, and you'll replace it when its stolen.   If you buy a donkey, you might just say "<deleted>" when its stolen, and go back to taxis.  Buy a good strong u-lock, and think about how much fitter it is making  you, carrying all that metalwork round.

[Samuel Smith]

My son (10 years old) has a 24" trinx.  The only weakness is the forks.  But it was a 4000 baht bike.  We do a lot of rough tracks & it copes well.  Compare the forks of the bikes you're looking at & the cheaper trinx bikes.  If they're a lot stiffer, shouldn't be a problem for what you want.  His bike, the forks are too easy to compress.

 

Alternatively, look at the Decathlon mtb at 17,000 baht https://www.decathlon.co.th/en/p/8394855_-275-rockrider-560-.html#/5883-200-m 

Better specs thab same priced Treks etc

17k is too close to the price of an entry level mtb like a specialised pitch or a low end trek but without the  resale value that comes with a brand name

i thought  about removing the paint with a wire brush head mounted on a drill or maybe spraying whole thing matt black and then roughing it up with sandpaper

but thats a lot of hassle when you need to do the wheels,shocks and the handle bars and seatpost etc 

tires and brake discs and shimano  components  would still look new  as well unless you want to give them the "treatment" as well

dont worry lol ,i wont be gentle with it and im about 90kg

 

i dont slow down for obstacles or rough bumps  and if  anything  breaks il update the thread so everyone else knows not to buy one 

 

the x1 shocks are filled with  compressed air rather than  a spring coil so i dont really know how to set the psi correctly yet   ,

IN a few days il know if they can handle  basic jumps,train tracks  and a flight of stairs etc ........;)

 

unfortunately the 29er was sold out at the moment so the 26" will have to do .......

 

 

 

 

 

[CNXBKKMAN]

A lot of people are mentioning the 29 wheel size but my experience in Thailand are they are not so popular so there are very few tyre choices compared to 27.5 and 26. I would go for the 27.5 model or the 26 if you are not very tall. 

[ttakata]

I rattle can sprayed my fatbike to matte black because it was a very shiny green.  I just sanded the paint with 600 grit and sprayed the frame only.  I purposely left the black fork and handlebars alone because they have garish Totem brand logos printed on them.  Any fool with a phone can look it up online and realize its just a 15k bike.  I've had it locked up in a public garage for 2 years now although it does have a good lock on it.  Another cheap way to downgrade a bike is to cover it in stickers.  Lazy thieves will pass on a 10k mtb with a good lock on it when it would be easier to steal a motorbike.  Thais are more trusting since I've been to condos and see many 10k bikes in the car parks with just cable locks.

So how is the X1?  Are the shocks OK?

Seems to be fairly bulletproof so far for the price

Everyday I'm waiting to see what breaks first but so far nothing has :) 

I usually keep the shock locked and  the tyres at 60 psi for around town but I haven't used it as much as I want to yet because I haven't had time to buy a good lock and I don't want it to get stolen already
