Firstly, by all means buy this group or a bike spec'd with it, but spend the money to upgrade the brakes, if only the pads. The brakes are the Achilles heel on this group and unfortunately, IMO, that's a pretty bad place to be terrible...
This is a very solid group, and, except for the brakes and the position window on the shifters, is basically the same as the 5600 105 group. I don't think it shifts quite as smoothly as the 5600, but it's still pretty good when welll tuned.
Aesthetically, I really don't like the shifters--I don't like the shift position windows on the top of the shifters--but they work quite well nonetheless.
The derailleurs work well with a minimum of fuss and noise.
The brake calipers, as far as I can tell are the same as the 105 calipers, but have a different brake pad; where the 105 group has a shoe and pad insert, the Tiagra brakes come with a smaller (by about 15% in surface area) pad that is a "combined" unit. Upgrade this immediately.
A great group set for the price, but the brakes, I just can't stress enough, upgrade them!!!!
Strengths: This group shifts and functions just as well as any other groupset out there if properly adjusted and maintained. Hard to argue the price isn't good for a group you can ride for years.
Weaknesses: It is a heavier groupset than most.
In a little over 2 years, I have put 35,000 miles on my Tiagra group. I race this group in the pro12 field as well. This groupset works flawlessly if it is properly maintained and adjusted. One can easily shift mid sprint with properly adjusted Tiagra. If you are having "problems" with the shifting and various noises, it is user error, not the groupset. The idea that 105 is the lowest you want to race is absolute rubbish. In terms of group weight, you get what you pay for. One can easily race Tiagra at the national level if they have the legs for it. Quit blaming the product for problems created by the user.
Strengths: STI shifters are the best in the business, shifts are smooth, and not obtrusive, clean looking design, being abe to break and shift at the same time, rarely fails
Weaknesses: A little on the heavier side, Rival in comparison seems a great value, Not a great groupo to show off to others riders on a team
I've had Tiagra on my road bike for 6000 miles now, and it quite simply hasn't missed a beat. I'm sure that other group sets will do the job quicker while being lighter, but that's the beauty of Tiagra, I simply don't have to worry about it at all because it's so cheap and durable. My only wishes is that it was a 10 speed, and that it was a little lighter, especially the crank.
Strengths: Functionality, price. Tiagra is hardly sold as a groupset in the States but online you find the Tiagra group for very interesting prices. IMO maybe the best price-quality ratio of all groups.
Weaknesses: Only 9 speed. Hoods are quit long and narrow for those with short hands.
To begin this review with I have to say that I have a mixed 105 and Tiagra groupset. The brake caliphers and FD are 105, the crankset, RD, shifters, cassette and hubs are Tiagra.
I have been reading some negative about Tiagra but honestly, the Tiagra pieces I have work flawlessly. For above mentioned reasons, I can't judge the brake caliphers and FD, but the RD is very good. The crankset, I am almost sure uses the same chainrings as 105 and the integrated spindle design offers the stiffness you find in high end cranksets.
The shifters have the same features as other Shimano STIs, but are 9 speed. You can shift from the drops or the hoods without problem. Shifting is smooth and once set up well, does not miss a cog.
Weaknesses: Shifters are junk, derailleurs are sluggish and inconsistent.
Absolute rubbish. Rear shifter is sluggish and jumpy, front derailleur won't stay adjusted. Front shifter has broken on me twice in six months, leaving me stuck in the large chainring. Both times it has been covered by warranty, but it's ridiculous that I'm on my third shifter in six months. I'm also getting noise from the bottom bracket with less than 1000 miles on the bike.
Is it possible to replace a left tiagra 9s double shifter with a left tiagra 10s double shifter?
The Ratchet inside my left shifter has broken and I have been advised to replace the whole thing. I was quoted £200 for a new pair but given my bike was a bargin secondhand at £300 and only one is broke ... Read More »
I'm not sure why I'm even pointing this out but I noticed they went to a Tiagra rear casette on some of their models, including the full 105 and Rival model Tarmacs.
I actually have a new Tiagra, 5700 105 and 6700 Ultegra cassette on hand (trainer, stock wheels, new wheels). While the 6700 is def ... Read More »
[COLOR=#181818][FONT=arial]I have been looking at the Madone 2 series from Trek. I'm wondering if anyone has any opinions to share. I like how the drivetrain is mostly 105 but the crank is a Shimano R565 and the cassette is a Tiagra 12-30. How do these latter two parts measure up in terms of perform ... Read More »
Hi all, :mad2:
I have a 9 speed Tiagra 4400 Right hand shifter (old generation befroe the "gear selector window" was added to the design), and its in bits!
I got given a set recently by a mate and the plan was to us it on a 1x9 cross bike. the shifter then jammed, it appeared that it had shift ... Read More »
