Sepeda Lipat Balap Bike Friday Pocket Rocket Pro - 2012







Brothers and Bike Friday co-founders Alan and Hanz Scholz come from a background deep in the bicycle lifestyle and filled with innovation

Bike Friday's Founders were raised on racing, so the Pocket Rocket is designed with one simple goal in mind: match that classic road bike feel.
We took all the best elements that made the Pocket Rocket a popular road bike and cranked it up a notch to design the Pocket Rocket Pro, made in Oregon - USA
You should know this. Our Founders are hard core roadies, and they have the medals to prove it. They raced their way off the windy plains of North Dakota with a simple goal: Design a travel bike that performs like your best road bike.

Our road bikes have that pedigree. Our Head Designer, Rob English, is at Cat. 1 racer in Oregon.

Serious roadies who accept the fact that our bikes look different quickly learn that's the exception. The rule is they excel on the road. We design with classic road bike frame geometry, dress with high end components and, best of all, like all our bikes, they fit in a suitcase and travel with ease. They don't usually replace your road bike but they do match it when you travel so your best training continues to keep you on schedule.

With double-butted tubing, improved bracing and new fork the Pocket Rocket Pro is both lighter and stiffer.


How light?
A Dura-Ace equipped model with racing saddle and Speedplay pedals tips the scales at less than 20 pounds (9.1kg)!

The Pocket Rocket Pro is full Custom to your choice. That means you have a wide array of options for your components from Shimano, SRAM, Campy, Chris King, FSA, Phil Wood, Rohloff, Thompson, American Classic, Avid, Terry, Cane Creek, DT, Alex, and others.

You can Customize your Pocket Rocket Pro to any number of speeds from single speed to 30. Our Custom frames run from 48 cm to 62 cm, and we offer the full variety of color choices for frame, cables, decals and bar tape. Contact a Bike Consultant to learn more.


Review pribadi : Luar biasa untuk sepeda lipat ini, nggak salah deh buat dikoleksi, pengalaman yang sangat tidak dilupakan adalah saat gowes di Sentul Bojongkoneng, saat di grade 19% stiff banget dan nyaman (bahan Chromolly) tidak "mentul mentul", energy safe, geometri size sangat fit dengan ukuran badan, tidak seperti sepeda lipat merek lain yang hanya mengeluarkan 1 size untuk semua ukuran badan, tersedia ukuran 52 cm, 54 cm, 56 cm, 60 cm, benar benar sepeda lipat dengan rasa Roadbike.

Di etape datar agak keteteran saat bermain hi speed, karena ukuran wheelset 20 inc, penulis pernah mecoba di datar mengikuti di belakang pelaton (Foresta - BSD Serpong), maximal speed bisa mencapai 46km lewat dari speed itu udah berat karena over cadence, jika dipakai ITT sendiri, maximal speed 37km, crank 53/39 sproket 11-36.

Disarankan jika memiliki power lebih, bisa memakai crank ukuran 56 atau 58 dengan sproket 26, speed lebih dapat atau anda bisa mencari sproket dengan ukuran terkecil 9T (standar 11T), tetap dengan 10 Speed, Capreo adalah sproket special order.

Walaupun Pocket Rocket adalah jenis sepeda lipat tetapi dari segi performance termasuk kategori sepeda balap, geometri 100% menyerupai sepeda balap umumnya, terutama dari segi akselerasi nya sangat cepat karena memakai ukuran ban 20', jika anda bermain di dalam rombongan roadbike saat mencapai speed diatas 38km sebaiknya anda sembunyi di belakang pelaton untuk menghemat energy, kelemahan di ukuran ban 20 adalah di Top Speed , need more energy, dengan strategi sembunyi di belakang pelaton saya jamin anda tidak akan copot, ukuran Pocket Rocket yg lebih kecil dari Roadbike menjadi keunggulan utama saat anda di posisi belakang pelaton yaitu "Drag Wind" (hambatan angin) lebih kecil.

Untuk pemakaian harian, anda bisa menggunakannya untuk recovery dan latihan RPM di tanjakan.
Sekali lagi di trek datar akselerasi nya sangat cepat, Bike Friday Pocket Rocket Pro juga sangat nyaman dipakai di event Audax dengan kontur trek datar dan tanjakan curam.

Mengapa buat touring jauh atau event Audax lebih disarankan memakai folding bike Bike Friday?

Ini salah satu komentar dari pemakai Bike Friday dan ini sangat sesuai dengan pemikiran saya :

Thanks Rob English for introducing me to the BF as a serious bicycle through his entertaining web site , I have just completed my first 1000 km on my new retro Pocket Rocket, financed by selling my cherished Eddy Merckx (Litespeed, or is it the other way around?. As I travel a lot I got sick of the hassle of bike bags and the inevitable damage incurred by bagge handlers. The real bonus is that the bike itself is so much fun to ride and as good to ride as any high end racing bike, Thank you Rob English you are a great advocate for the product and Epic cycles in Brisbane are very enthusiastic agents.

Selain itu, dengan bahan besi cromolly anda tidak perlu khawatir retak atau patah di frame, dengan ukuran roda 20 inc, sepeda ini sangat lincah dan gesit di handling, beda dengan roadbike, anda tidak bisa menikung tajam, begitu juga dengan ukuran sepeda yang lebih kecil dibanding roadbike, lebih aman, jika seandainya "jatuh" dari sepeda.

By Rob English

I am a Cat. 1 road racer, current Oregon Time Trial champion and long time bike geek….

I’ve also been a Bike Friday owner for 11 years — I bought a Pocket Rocket several years before I came to work here.
I have used my Bike Fridays for touring and riding all over the world, including hitting the local hammerfest rides in various countries. And I have done a few races on them, too.
First, the USAC rules question of whether or not Bike Fridays are legal — it is going to depend on the level of the race and how strictly the rules are applied.

Generally USAC follows UCI rules and a Bike Friday is not UCI legal as the wheels are too small (too much of an advantage?!!?), and it doesn’t have a double diamond frame. In most of our customers’ experience, for local races, organizers don’t have a problem with Bike Fridays racing. But at National level they will!

I have always greatly enjoyed showing up at the local fast rides wherever I might be, getting the usual derision of the bike as not being a ‘proper’ bike, then making people change their minds after I drop them on the hills! Very entertaining to educate people about performance small wheeled bikes! I have never felt at a disadvantage in being on the BF on any group ride.

When racing the Bike Friday, I have found that it is very competitive on hillclimbs (I won an open hillclimb in Japan on my Pocket Rocket), and does well in road races, except at the very highest level — doing Elite races in New Zealand I found I had to work a little harder at the very high speeds (32 mph+). To be fair this was on my Pocket Rocket mainly set up for touring — with the Rolf wheels and faster tires on the Super Pro this small difference may be mitigated.

I have traveled with full size bikes in soft and hard cases, a full size folding bike in a hard case, and the Bike Friday in the suitcase. For ease of use the Bike Friday system is unbeatable. I can pack and unpack the bike in under 5 minutes, compared to a minimum of 30 minutes for any other system. And the packed bike is so secure that I never have to worry about the bike getting damaged in transit. Add in the ability to ride to the airport towing the suitcase/trailer and there is no question of the best travel bike in my mind.

Gearing: 53x9x20″ is 118″, 53x12x27″ is 119″ and 53x11x27″ is 130″. So the Capreo gearing gives you the equivalent of a 12T; if you think you will need bigger then going up to a 55 or 56T big ring will take care of it. I have generally run non Capreo, using either 58x11x20″ = 105″ or 62x11x20 = 113″ and have never had a problem with running out of gears. The Capreo option does avoid the dinner plate size rings though! The Capreo cassette is available from other places, but most bike shops haven’t heard of it, so it can often be easiest to get spares from us. Everything else on the bike is standard though.

A couple of other points: The Pocket Rocket Pro has an incredibly stiff drivetrain — the very small rear triangle in steel gives very direct power transfer. But with the long titanium seatmast, there is a nice amount of passive suspension built in so that it is very comfortable too — that much quoted combination of laterally stiff and vertically compliant…..

In a paceline situation the small wheels enable you to get a little closer to the rider in front, and thus get more draft and less effort. This is great when in a paceline of several Bike Fridays (i.e., our lunchtime ride), as everyone is much closer!

I hope this helps give you some information. I don’t know if you have heard the story of how the Super Pro came to be — we have a customer who had a Pocket Rocket Pro and loved the ride, but wanted something lighter to compare to his custom Seven. He inspired us to create the Super Pro and got the first one, which he then took on the PacTour TransAm — 3000 miles in (I think) two weeks! Bob is in his 60s and takes great pleasure in crushing younger riders — doing it on small wheels adds to the satisfaction!

Let me know if you have other questions I can help with,

best regards,

Rob.
