Shimano Shifter Price In Bangladesh

Shimano's 105 R7100 Di2 brings semi-wireless electronic shifting to its mid-level groupset, and an extra sprocket to boot, bringing it into line with range toppers Dura-Ace and Ultegra. Some will mourn the lack of a rim brake option, but if you are happy to embrace some of the best performing hydraulic braking power and electronic shifting on the market, this is probably the most cost-effective of all the higher end Shimano road bike groupsets. It's pushed hard on price by its main 'Rival', though, the aptly-named SRAM Rival eTap AXS groupset which is a fair bit cheaper.
Brilliant, basically. I've spent time on all of Shimano's Di2 groupsets right from the first iteration Dura-Ace up to the present models, and while early releases saw big jumps in performance and usability, the recent couple of updates of Ultegra and Dura-Ace have been more about refining the quality from the previous model, and that's the point where 105 joins the throng.
While shifting quality and braking is important, comfort and ease of interaction with the STI units is probably the most crucial. After all, you aren't changing gear all of the time, but you will be riding on the hoods for many, many miles.
The 105 shifter units are identical in shape to the Ultegra and Dura-Ace offerings, with large buttons that fall naturally to the fingers even if you are switching between Shimano's mechanical and Di2 groupsets.
With the brake reservoir, but without any mechanical components for the gear changes, Shimano has managed to create an STI unit that mimics its mechanical rim brake offerings for size, meaning less bulk than SRAM's units by a small amount.
The curve of the brake lever allows your fingers to settle naturally in position, and thanks to the power of the hydraulic system, you can brake heavily using just two fingers. Unless you were using it all of the time, the early Di2 units took a bit of thinking about where your fingers needed to be to shift, especially when wearing gloves. These new units don't have that, everything just feels naturally positioned and I never fluffed a shift.
To test shifting under load, I'd hit my local 20 per cent climb in the big ring before dropping into the small ring when my cadence had dropped to around the 30rpm mark, and while anyone with even an ounce of mechanical sympathy will wince at the thought of shifting a chain across chainrings at this point, 105 doesn't share your concerns.
I must admit I do like SRAM's idea of smaller chainrings paired to a wide-ranging cassette as found on its latest Rival AXS eTap groupset. It feels efficient to me, barely having to drop down from the large chainring until hitting the steepest of climbs. There are trade-offs with the SRAM cassette sizes, though, but more about that in a minute.
Shifting from the front mech is great, with plenty of power to move the chain even under heavy load, and the automatic trimming mode works as well as always, tweaking the chainline as you move up and down the cassette.
According to Shimano this is the brains and hub of the Di2 unit, incorporating the charging port, adjustment switches and everything else. While it uses Shimano's Shadow technology, which sits the mech underneath the cassette in a bid to keep it out of the way, should you crash it's still going to be one of the most vulnerable components, and pricey to replace.
SRAM's 12-speed cassettes offer a 10T sprocket which works with its smaller chainrings to still give a large gear ratio. To create the wide-ranging ratios, though, they do tend to have large jumps at the upper end of the cassette, something that Shimano doesn't suffer from.
The chain selected for the 105 groupset is from the mountain bike SLX line-up. It comes with a quick-link assembly and SIL-TEC treatment which Shimano claims gives extended off-road durability. Ideal if you are going to be using 105 as an all-year-round groupset.
The majority of riders using 105 Di2 will have had it come as part of bike package, but if you are going to buy it as a groupset for your own build, with all of the bits and pieces that you are going to need like wires, batteries and so on, it's going to set you back 1,730.
In terms of its performance and rider integration, I can't fault 105 Di2. It's a great groupset and looks awesome too, with its gloss black finish. I can't help feeling it's a shame that the upgrades haven't been brought across with a mechanical groupset, but hey, that's the future I suppose.
It isn't as good value as its main rival, though. Prices for fully built bikes with Rival eTap and 105 Di2 aren't that different, but buying a groupset for your own build, at full RRP, SRAM offers better value for money over Shimano.
Shimano says: "The new SHIMANO 105 brings Di2 shifting to a new set of riders. For those who have only experienced mechanical shifting and ergonomics, SHIMANO 105 Di2 represents a transformation of the road cycling experience."
As part of the tech team here at F-At Digital, senior product reviewer Stu spends the majority of his time writing in-depth reviews for road.cc, off-road.cc and ebiketips using the knowledge gained from testing over 1,500 pieces of kit (plus 100's of bikes) since starting out as a freelancer back in 2009. After first throwing his leg over a race bike back in 2000, Stu's ridden more than 170,000 miles on road, time-trial, track, and gravel bikes, and while he's put his racing days behind him, he still likes to smash the pedals rather than take things easy. With a background in design and engineering, he has an obsession with how things are developed and manufactured, has a borderline fetish for handbuilt metal frames and finds a rim braked road bike very aesthetically pleasing!
Somehow they have made Di2 even less attractive. Still with the small, fiddly lever blades, the wiring and the expense. Still with the larger number of potential failure points and no obvious benefit - I've borrowed a couple bikes with it and was expecting perfect, lightning-fast shifting. But no, it was Shimano 11 shifting ... but you push a button.
I still cannot see any benefit to me as a rider over my Shimano 11 mechanical (other than the extra couple of teeth in gear range) setups or my two Campag 11 mechanical / rim setups, all of which just work. One of my Campag setups cost me c. 600 brand new, has given me zero issues and (if it matters, which it doesn't if you're not racing) weighs about the same as Ultegra 8000 mechanical.
If I was looking for new 12sp, I wouldn't even go to AXS, I'd be going straight to the appropriate Chorus mechanical, which is 600-800 cheaper depending on whether you want hydraulic braking. Undocumented feature - you can make Di2 "bweeee" noises yourself when using the left lever!
The reviewer draws an odd conclusion on cassette sizes. First Shimano are criticised (rightly) for the lack of choice, but the criticism of SRAM for bigger jumps between gears is misplaced, as this only applies to the extreme wide range 10-36 cassette. In fact for those wanting smaller jumps between gears, SRAM win hands down with their 10-30 which has smaller jumps than either of the Shimano offerings. The point here is that SRAM Rival offers a real choice of wide range or close ratio cassettes , whereas Shimano's two choices are remarkably close together, making it really, not much of a choice at all.
The component world has finally joined the 'throw away culture' band wagon. For example should your front mech' fail you'll have no option but to buy a new unit as the item hasn't been manufactured with 'repair' in mind. This is a retrograde step for both the consumer the planet.
Exactly. The planet is on the brink of ecological catastrophe, we are about to enter a recession with cost of living crisis, fuel prices are out of control and the manufacturers think this is the direction cycling should take.
I'm tempted to start working on a business startup. Performance cycling components in industry standard sizes, consumer repairable, low cost, no electricity, lighter and basically faster, far cheaper and eco-friendly alternative to the crap being pushed on the public.
ETA: Just checked. Campy and Shimano 9 speed came onto the market in 1997 and 1999 respectively. That means the patents have expired (20 years), I think. With updated materials, you could produce groupsets lighter and at least as durable, using designs based on these. Anyone fancy investing in the future of cycling, drop me a line.
Generally same with the rear, jockeys can be replaced. I once replaced the bolt that attaches it to the frame (utter nightmare) but that was weight saving, and the main spring could be changed to mitigate the effects of filth.
I speak as someone who has kept his 7/8 speed XT system going for over 20 years by getting stuff second hand off eBay, making sure stuff was not too worn by checking out how it looked, and then using it untill it died. Pivots dieing on the brake levers were the most frustrating. Started lubing them with finish line's SPD PTFE lube a while back.
Yes Shimano, because cyclists want less aero, heavier, more expensive groupsets that cost three times what the old ones did. I become more wedded to mechanical rim brake as every day goes by. For road cycling in particular, it makes so much more sense than the nonsense being pushed on consumers.
If you want this nonsense and have more money than sense, then by all means buy it. But if you can pay less for a faster, lighter, at least as aero bike then why wouldn't you? So these new groupsets are just a huge way of making performance cycling at least seem less accessible. Who is going to be honest and tell the public, that are new to cycling, that my old best bike with a mechanical rim brake 10 speed groupset is actually lighter, more aero, easier to maintain and cost significantly less. Yes, it's faster, more aero and cheaper. Pick all three. What is a smart person likely to do?
I would love to start a pro cycling team that ran on 10 or 11 speed mechanical rim break groupsets and raced on quality aluminium framesets with standard handlebars and seatposts... The manufacturers would shit themselves.
