Shimano 105 Groupos Reviews

Price Paid:  $0.00

Favorite Ride:
Colnago Master X

Summary:
The 5700'series is ok. The cassette and chain is subject to accelerated wear in the first 1000 miles. I've got a vintage road bike with the original suntour chain and cassette clocking in at 145,000 miles so to compare with Shimano, I'm not too impressed with Shimano's durability.

Strengths:
Shifts ok and quick and great price point.

Weaknesses:
Accelerated wear for 1000 miles is not greatest. It's about the same wear as Sora and 2300.

Similar Products Used:
Shimano Ultegra, Sora, 2300, Suntour

Price Paid:  $950.00 at Pedal Power--Lexingt

Favorite Ride:
Giant FCR 1

Summary:
Very easy to use, but the Shimano 105 groupset is pretty noisy; the chain chatter is pretty loud, especially in all cogs on the large chainring. I've taken it in several times already, but the shop hasn't been able to remedy the problem. I just hope I don't experience the same problems the other reviewers have had.

Strengths:
easy to pedal, very stable (especially for a non-racer like myself)

Weaknesses:
Noisy rear derailleur

Similar Products Used:
Shimano Deore

I had chain clatter, but only with the big chainring, w/ 2 and 3 on the cassette. It drove me crazy. Took the bike in several times, but always the same result. Finally I put the bike on a stand, and closely watched and listened as I turned the crank. I could see the chain rising up briefly on one tooth of gear 2 and also 3. When the chain came back down, it made a sort of "slap". I figured that the 2 gears were not quite to spec, or had a slight bend in them. I bought a new Ultegra cassette and chain, and that fixed it. Also, the first ride after washing the bike seems to be a little noisy. After a couple of coats of chain lube build up, the bike rides virtually silent. I love it!

Shimano 105 is recognised as a silent and smooth shifting derailleur. There is one simple rule, when you change your chain, change your cassette and your crankset gear...

Price Paid:  $0.00 at Amity

Favorite Ride:
Bantam Lake

Bike Setup:
Specialized Allez (stock)

Summary:
Bad experience so far. While on a ride, I lost the ability to shift into high gear. Shimano 105 front shifter is graciously being replaced by the nice fellows at Amity Bikes, however, this is not something you expect to be dealing with on a new bike. Hopefully this is a one time thing... Nice weather has arrived in CT, and I'm without my bike :(

Strengths:
Comfortable bike so far

Weaknesses:
Shimano 105 shifter

Price Paid:  $0.00

Summary:
Shimano 105--has jumped off and locked up on me several times-most recently today (March 28 2010) broke off at the deraileur---lodged in the spokes and cracked a fiberglass frame. Shimano will hear from.

Weaknesses:
see abve

Price Paid:  $1300.00 at an NYC bike shop

Favorite Ride:
haven't found it yet

Summary:
so, my experience with 105 has been terrible. it came on my 2010 cannondale caad9 5, and has been back to the shop six times. the problem still hasn't been determined, but basically the shifting is terrible. it skips gears, ghost shifts, or gets stuck between cogs. if you are in the market for a new bike, i would avoid anything with 105 on it. i just purchased the SRAM rival upgrade kit and can not wait to be rid of the headaches.

Strengths:
none

Weaknesses:
see above

Ever think to check the alignment of the frame. esp. the Rear Dera Hanger?

what do you think the shop has been doing each time it's been back? yes, everything has been checked.

You bought a brand new 2010 bike that will not shift properly. You've had it back to the dealer 6 times and they cannot determine the cause of it. My advice is to find another shop to install your new Rival group unless your incompetent shop is paying full parts and labor.
