Re: looking for a frame with modern geometry
The answer to the question is pretty simple.........Law. Most of the carbon frames are built in Asia by factories not owned by the bike companies. When they design a new frame and have this Asian company build it, they make them sign confidentiality agreements. They are not allowed to use any proprietary knowledge learned from building frames for others. If they do they are breaking the law and can face legal penalties not to mention loose a ton of work from others they might be building for who may no longer trust them. That's why what you see coming out of open mold designs is older technology. Those agreements on those designs have expired and the frame builder can use some of that technology on their own frames. I have a DengFu M06 and that design incorporates some newer technologies like a 68.5 head tube angle, 73.8 seat tube angle and 435 chainstays. Yeah not 425-430 but for a full suspension frame that's pretty short. If you're looking for the latest and greatest technology from a Chiner builder you're pissing up a rope! They are not in the business of design, their forte is manufacturing. October 26, 2017, 10:42:28 AM |

ICAN SN04 Full-Suspension Fat Bike review
I have a great experience to share with the ICAN SN04 full-suspension fat bike model. It is quite something for a company to open a mold for such a niche bike like this, and after some deliberation between the other full-sus fat models (Angle Sports and Xiamen Carbon-Speed, specifically), I pulled the trigger on the ICAN. The price was $50 more than the competition, but the frame was kitted up with better hardware, screws, and the service was stellar. Shipping was faster than any of the other 10+ open mold frames I have ordered over the years. Out-of-the-box Impressions The paint job was spectacular, and the frame came well packaged and really caught my breath when I put it on the stand--it is so well finished! I thought Salsa Bucksaws looked trick, but this thing really does! Riding Impressions Geo is very reminiscent of, shall we say, the bucksaw. It rides a lot like a bucksaw, feels a lot like a bucksaw, and similar suspension kinematics. It feels heavy on the uphills, but unconditionally roars on the downhills. That's going to be the reality with most full-suspension fat builds, and I had mine built up with various kits to between 32.5 and 35 pounds. I took the 35 pound build down the trails at Burke Mountain Bike Park in Vermont, and can't forget the priceless expressions on the lift assistant faces when they lifted the fat bike onto the chair. They remarked that they'd never had anything heavier or bigger on the mountain. At it's best with an ultralight carbon wheelset, 4.0 Jumbo Jims, and a RockShox Bluto fork the bike was ridiculously fun on dry singletrack, but uphills were tough. At it's worse with 4.8" Vee Snowshoe XLs and a Manitou Mastodon comp fork, the bike was alright on groomed singletrack and absolutely lead-heavy uphills--not fun at all. Maximum Tire Size and Warranty Experience I broke the rear chainstays with a 4.8" tire fully inflated while running a RockShox Monarch RT3 at ~280 PSI. This tire size is too wide, and I'd never recommend going over 4.5", I don't see why you'd have to. ICAN was extremely fast to reply to my warranty request, however, and sent TWO--not one--replacement chainstays with hardware by express DHL. Absolutely phenomenal service! Absolutely recommend this company. Afterthoughts This is not a bike for un-groomed snow, wide tires, or a do-it-all kind of rig. It's very niche, but super-fun on the downhills. I'm a ride-and-sell kind of guy, and I usually get my money back after building a bike. Of 10+ bikes I've built up, ridden, and sold, this was the only one I lost money on, and I lost over $800 on it. But it was incredibly fun to ride when built up at 32.5 lbs, it was just too niche for me and I didn't need FS fat. ICAN has done a wonderful job with the frame design, customer service, and warranty fulfillment, but I would just encourage anyone looking at full-suspension fat to really consider what they are looking for in a bike and how much they are willing to spend.

Re: LCFS911 full suspension
Quite basic build... Reba 120mm, xtr m9000 race brakes, XT M8000 gears, sunrace 11-40 cassette, American classic hubs, DT-Swiss Competition spokes, Nextie carbon id30mm rims, Brand-X dropper post, chiner saddle, Easton carbon bar, Rocket Rons ss 2.2", RF Next cranks, eggbeater pedals, Monarch 165x38 RCT shock. Weight approx 11,3-4kg include pedals and bottle gage. There is no need for lock outs. This frame is unbelievable good and pedal efficient. It's still very comfortable and sensitive, even for small chatter. My previous bikes were cube stereo and Epic S-works, and this frame beats them both. This is absolutely the best fully frame I never owned. Lightcarbon bikes deserve extra points. The first frame they delivered me was a bit thin in bottom bracket area. And the bottle gage rivets were quite high. It was no possible use 750ml thermal bottle. I wrote them about these issues, and they sent me a new frame that the issues has improved. I had to pay only postage costs!! And they let me keep the old frame! This frame is really solid, light, effective and fast enough for compare any "hi-quality" brand frame. I'm really happy with it. I use it for XCM and XCO racing and light trail riding. With 120mm fork and dropper the bike is really capable even the nastiest trails and rock gardens. And the cons... sorry guys, haven´t found any. May be the bottle gage rivets could be 15mm lower... May 28, 2018, 09:44:42 AM |

Serpah FM199 Drop Bar MTB Build
I wanted an aggressive gravel bike that's able to fit MTB tires. Trying to copy a Salsa Cutthroat with a Chiner frame. I basically wanted ~70mm BB drop, clearance for 29x2.25, chainring clearance for 36t+, and modern XC geometry (100mm fork geo, ~69 deg headtube, etc). I usually ride large MTB's (I'm 5'10.5") so I ordered a medium FM199 frame from Serpah on Aliexpress. It arrived in 9 days from ordering and was packaged very well! -Serpah FM199 Chinese Carbon 29er MTB Frame -SRAM Rival HRD 1x w/ 38t and 10-42 -Teravail Sparwood Tires on ARC27's laced to Novatec hubs (my first wheel build!) -Niner Boost RDO Fork -Tranzx Dropper actuated with left shift lever -Ritchey VentureMax bars The main setback on the build was routing the rear derailleur cable. This frame is intended to run bare cable through the frame, but I like to run full housing so I drilled through the frame fittings. The DS chainstay is THIN inside, I had to grease up the housing and use a bit of force to get the housing through. With Jagwire 1.1mm cable there's no issue with stiction. Other than that the build was super straight forward, the BB was solid and the PF BB went in no problem, no creaking yet! Headset area was solid, the rest of the cable routing was easy, everything else went together in one night. This frame is weird that the rear caliper is set up flat mount, but they include an adapter. Luckily I'm running a road groupset so I actually am running flat mount in the rear and post mount in the front. Since there's only clearance for 29x2.3 tires and it's boost spacing, the DS chainstay runs parallel to the centerline a ways past the chainring, I'm sure I could fit a 40t or 42t no problem. It weighs 21.9 lbs as it sits in the pictures. I also have carbon road wheels that will get the weight down to 20.5 or so. I could drop another pound or so off the gravel weight if I went carbon with some lighter spokes, but I'm pretty happy as is. The wheels are 1840g without tape or valves. I found a nice gravel two-track trail that leads into a tight single-track trail and then leads to a long dirt road, this bike was perfect for that! I want to get it out on some longer single-track trails to see how it does.

Re: Carbonda fm936 Thoughts
I am in the process of ordering a frame and I disliked the idea of another possible press-fit dissaster so i asked if BSA 73mm is a posibility and apparently it is! I was curious as to how this was possible because the original shell is 92mm wide, but it looks like they are able to shorten the flanges of the original shell to 73mm with aluminium threaded inserts. I asked about weight differences but he said 'no difference' which i interpret as negligeble. Adam sent me these photos.

Re: TanTan FM10 29/27.5+
Shes all built up, but still needs dialing in. Maybe a shakedown run tomorrow. Most of the parts are obviously well used from my last frame. The Manitou Magnum was stretched from 140 to 153mm travel. Drivetrain is all new except for the crankset and a worn out absoluteblack oval that desperately needs replacement. Have a Wheels-Mfg thread together BB to keep from developing any creaks. Wheels are nextie i45 carbon hoops on sram 900 hubs. Brakes are simano zee with 203/180 hope rotors. All around solid bike. Ive been riding a big split in travel (140/100) for so long, this feels really weird to me right now. Let me know if you guys want any detailed / close up pics of any specific areas, and Ill snap a few tomorrow. June 12, 2020, 05:33:52 PM |

Re: Carbonda fm936 Thoughts
Riding a 42.5 shock I can tell you the chance of having isseus is minimal. Rode a bikepark!! with this bike without problems. Even cleared a jump of several meters! Did also some enduro tracks in the Dolomites(Italien Alps) as xc biking there and it was great. Better than last years biking with a canyon nerve; better going up and way better going down.
