29 inch bike front derailleur: the BERG 3.0 chainset record has limits
A 29 inch bike front derailleur enquiry can become confused when the crank, shifting control and rear mechanism are described as one Shimano system. Kross's BERG 3.0 lists them separately. Its front derailleur is Shimano Tourney TY300, while the crank entry says Prowheel and leaves the chainring tooth counts unstated.
Find the 29 inch bike front derailleur in its own row
TY300 belongs to the front mechanism in this equipment list. The Altus M310 name belongs to the rear derailleur. Keeping those positions explicit avoids turning a request about front shifting into an order based on the rear component's designation.
The shifter row adds Shimano Altus M315. That is another identifier, rather than an alternative name for TY300 or proof that the crank is made by Shimano. The Kross BERG 3.0 Bike — Black Glossy provides the complete-bicycle identity to carry alongside these individual names.
Keep the missing chainring sizes missing
The crank row supplies Prowheel without a detailed crank model or ring tooth counts. A 3X7 headline explains the front-and-rear arrangement, but it cannot supply the absent tooth numbers. Do not borrow a familiar triple-chainset specification from another entry in the 29-inch bicycle collection.
This matters when the intended comparison concerns gearing or a replacement chainset. Record the markings on the actual crank and rings, then ask which exact assembly is involved. A bicycle advertised under the same model name may also have had parts replaced; the manufacturer's list is an original reference, not an inspection of that example.
Add the chain and bottom bracket without assuming a kit
Kross separately lists KMC HV500 for the chain and FP-B902 for the bottom bracket. Those entries make the component list more informative, but they do not turn it into a pre-approved replacement bundle. The applicable dimensions, installation requirements and compatibility of any proposed change still need confirmation.
The older FOCUS bicycle pictured makes the separation visible: crank, front mechanism and chain occupy different parts of its exposed transmission. It is historical comparison context with a 50-559 rear tyre, not the BERG's Prowheel or TY300 identification evidence. Its visible equipment must not be assigned to the current Kross listing.
For an enquiry, describe the actual task before listing parts: identifying a fitted chainset, investigating front shifting or checking a proposed purchase. The Kross range guide supplies background, while those precise component questions belong with the actual bicycle.
FAQ: The front transmission list
Which front derailleur does the page name?
It names Shimano Tourney TY300 in the front-derailleur field.
Are the chainring tooth counts provided?
No. The inspected crank row says Prowheel without those numerical sizes.
Which chain is listed separately?
The chain field identifies KMC HV500 for this documented build.
