Wittson is a bespoke framebuilding workshop based in Lithuania. Working exclusively with titanium, the father-and-son operation can build a frame for any riding discipline. electricity lesson plans middle school Aside from its custom creations, Wittson has a few standard offerings, such as the Suppresio, a race-oriented frame that capitalises on the strength and beauty of titanium alloy.

After more than two decades of involvement with the athletic side of the sport, Vitas was suddenly given the opportunity to enter the manufacturing side. It was 1994, and a group of investors had approached him for some help. They wanted to establish a titanium framebuilding company in Russia and could see that his experience and industry contacts would be invaluable to the venture. The fact that he spoke both English and Russian meant he could also help bring the new factory’s products to the West.

There are over 30 different grades of titanium alloy created by mixing the metal with small amounts of aluminium and vanadium, and in some cases, other heavy metals. grade 9 electricity module The bicycle industry typically makes use of Grade 5 and 9 alloys, where the former is prized for its strength, while the latter is available in seamless tubing and is much easier to weld.

One of the reasons Wittson chooses to use tubing from VSMPO Titan Scandinavia is that the company does not use recycled titanium. This is common amongst Chinese suppliers, but it corrupts the quality of the alloy, which in turn, can make it more difficult to work with. The choice may add to the cost of the final product, but it goes a long way to ensuring its quality, too.

The Suppresio is a race-oriented frame that has been stiffened in key areas. This includes the front end of the bike where there is an oversized head tube, tapered (1.125-1.25inch) fork steerer, and a bi-ovalised top tube. Elsewhere, there is an integrated seatpost, PF30 bottom bracket, and hydroformed chainstays. The rear dropouts (with a replaceable derailleur hanger) are made by Paragon Machine Works and all cables are internally routed through the frame.

One of the advantages of working with a bespoke framebuilder is that there is always scope to customise and personalise the final product. static electricity definition physics In the case of the Supressio, Wittson is prepared to make a variety of minor changes free of charge. Such changes include a BSA-threaded bottom bracket shell, standard seatpost, standard head tube, and fittings to suit electronic or wireless groupsets.

The stock Suppresio honours the beauty of titanium with a simple raw finish. The frame is hand-brushed, the logos are sandblasted, and there is a titanium head tube badge. The sleeves for the integrated seatpost recall an earlier era when lugs were de rigueur, yet they blend in with the modern oversized head tube, integrated cables, and hooded dropouts. Overall, there is a lot to admire about the Suppresio despite its subdued presentation.

The frame sent for review was a size S that weighed 1,972g with all fittings including the headset, uncut post and topper. gas chamber Uncut Enve Road 2.0 forks added another 372g. When assembled with a Campagnolo Super Record RS groupset , Pro Vibe alloy cockpit and Falcon saddle, and a Roval CLX 50 wheelset, the bike weighed a total of 7.49kg without pedals or cages.

Like the majority of small framebuilders, Wittson sells its frames direct to the customer. Prospective buyers can browse Wittson’s website to explore all of the options on offer before getting in touch via email or phone to start the ordering process. Once all of the details have been agreed upon, a 30% deposit is collected and the frame will go into production. electricity basics The lead-time for all orders is 30-45 business days, with the balance due prior to dispatch.

The Suppresio sells for €2,489 (~AUD$3,730/US$2,760/£2,140), which includes the frame, Chris King/Cane Creek headset with a choice of colours, titanium seatmast topper, bidon cage bolts, worldwide delivery, and a lifetime warranty. e suvidha electricity bill lucknow Import duties and taxes aren’t included in this price, though, which in the case of Australian buyers, will amount to an extra ~15%.

I really enjoyed driving the bike while staying seated on the saddle. With a set of high-profile wheels installed, the bike rolled well, and there was a pleasing hum. Swapping to low-profile alloy wheels changed the pitch a little, and if anything, added extra electricity to the feel of the bike. Either way, once I found my rhythm, I could ride the Suppresio for hours just to enjoy the sound and feel of the bike.

While there is a fair amount of hype and reverence for this kind of stiffness, its true value has yet to be proven. James Huang explored this issue in a recent podcast, discussing experiments that have failed to demonstrate an energetic loss between the cranks and the rear wheel along with the possibility that a flexible bottom bracket might return energy to the rider.

I didn’t attempt any of these experiments while riding the Suppresio, but at no point did I ever feel like it the bike was undermining my performance. In fact, the modest responsiveness seemed to suit the workhorse personality of the bike. year 6 electricity Nevertheless, for those buyers that prefer a rigid bottom bracket and rock-hard chainstays, I don’t expect the Suppresio will satisfy.

The Suppresio steady performer in the hills. At an even pace, there was nothing to separate the bike from any other. At times, there was a glimmer of agility to inspire my efforts, however the Suppresio wasn’t in the same league as a gifted climbing rig (to be honest, neither were my capabilities). As such, the bike was the perfect match for my measured approach to climbing.

I found the Suppresio was very stable, especially at high speeds, with neutral steering that tended towards slow. At low speeds through tight corners, I didn’t have much freedom to move the bike around, and I found I was better off taking a wide line to preserve my speed. Be that as it may, the bike was generally predictable and quite forgiving, so it was easy to stay on it for long periods.

My favourite characteristic of the Suppresio was its serene ride quality. This is something that titanium is well known for, and I really started to cherish it after I’d been on the bike for about a week. In general terms, titanium consistently takes the edge off the shocks and vibrations travelling through the chassis, but there is more to it than that.

The Suppresio is a good example where the sum appears to be much greater than its parts. j gastroenterol hepatol I can’t explain it, but the bike was always a pleasure to ride, regardless of how I was using it. That doesn’t mean it will be the ideal bike for every rider — the success of any bike will always depend upon on how well it serves the needs of the rider — but for those hoping for a well-rounded performer with a distinctive ride quality, the Suppresio might be a great match.
